CellList<Device> cellList = new CellList<Device>(new ItemCell());
where:
static class ItemCell extends AbstractCell<Device> {
#Override
public void render(Context context, Device device, SafeHtmlBuilder builder) {
if(device == null) {
return;
}
builder.appendHtmlConstant("<div>device.getId()</div>");
builder.appendHtmlConstant("<div>device.getName()</div>");
}
}
And now, I want to make an 'Edit' button, when I'll press on it - I want to see editable selected item. How can I do it? Please answer, who knows.
Use EditTextCell or ActionCell
addColumn(new EditTextCell(), "Name", new GetValue() {
#Override
public String getValue(IData contact) {
return contact.getName();
}
}, new FieldUpdater() {
#Override
public void update(int index, IData object, String value) {
try {
pandingChanges.add(new FirstNameChange(object, value));
} catch (Exception e) {
}
}
});

I followed the simple old way of doing this.
I used a cell list and a form attached to it. Every time you click on a row, row's data is loaded to the form. You can delete or edit the selected row via this form now.

I can't save User Setting of ComboBox like the TextBox or CheckBox? How to do that?
This is a simple example using .NET 5.
I created a form with a ComboBox ("comboBox1") and a Button ("bnAdd") to add a user-entered value to the ComboBox.
I added a setting with a name of "ThepphuongWCombo", type "String", and scope "User".
When the form is closed, the data from the ComboBox is saved, and the saved data is loaded when the app is run.
using System;
using System.Text.Json;
using System.Windows.Forms;
namespace SaveComboBoxToJson
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void bnAdd_Click(object sender, EventArgs e)
{
comboBox1.Items.Add(comboBox1.Text);
}
private void SaveUserData()
{
var json = JsonSerializer.Serialize(comboBox1.Items);
Properties.Settings.Default.ThepphuongWCombo = json;
Properties.Settings.Default.Save();
}
private void Form1_Load(object sender, EventArgs e)
{
// Show the location of the settings file being used in case you want to inspect it.
//var path = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal).FilePath;
//MessageBox.Show(path);
var cbData = Properties.Settings.Default.ThepphuongWCombo;
if (string.IsNullOrEmpty(cbData))
{
// Add some default values.
comboBox1.Items.Add("CCC");
comboBox1.Items.Add("DDD");
}
else
{
var itms = (object[])JsonSerializer.Deserialize(cbData, typeof(object[]));
comboBox1.Items.AddRange(itms);
}
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
SaveUserData();
}
}
}
The glass mapper will return null object or (no items) for SitecoreQuery and SitecoreChildren attribute that are placed on the GlassModels. These attributes don't take any such parameter where I can specify them to return items if they don't exist in the the context lanaguge. The items e.g. exist in EN but don't exist in en-ES. I need to put a lot of null check in my views to avoid Null exception and makes the views or controller very messy. It is lot of boiler plate code that one has to write to make it work.
In Page Editor the SitecoreChildren returns item and content authors can create items in that langauge version by editing any field on the item. This automatically creates the item in that langauge. However the same code will fail in Preview mode as SitecoreChidren will return null and you see null pointer exception.
SitecoreQuery doesn't return any items in page editor and then Content Authors wont be able to create items in Page editor.
To make the experience good if we can pass a parameter to SiteocreQuery attribute so it disable VsersionCount and returns the items if they dont exist in that langauge.
This is actually not possible. There is an issue on GitHub which would make it easy to create a custom attribute to handle this very easy. Currently you need to create a new type mapper and copy all the code from the SitecoreQueryMapper. I have written a blog post here about how you can create a custom type mapper. You need to create the following classes (example for the SitecoreQuery).
New configuration:
public class SitecoreSharedQueryConfiguration : SitecoreQueryConfiguration
{
}
New attribute:
public class SitecoreSharedQueryAttribute : SitecoreQueryAttribute
{
public SitecoreSharedQueryAttribute(string query) : base(query)
{
}
public override AbstractPropertyConfiguration Configure(PropertyInfo propertyInfo)
{
var config = new SitecoreSharedQueryConfiguration();
this.Configure(propertyInfo, config);
return config;
}
}
New type mapper:
public class SitecoreSharedQueryTypeMapper : SitecoreQueryMapper
{
public SitecoreSharedQueryTypeMapper(IEnumerable<ISitecoreQueryParameter> parameters)
: base(parameters)
{
}
public override object MapToProperty(AbstractDataMappingContext mappingContext)
{
var scConfig = Configuration as SitecoreQueryConfiguration;
var scContext = mappingContext as SitecoreDataMappingContext;
using (new VersionCountDisabler())
{
if (scConfig != null && scContext != null)
{
string query = this.ParseQuery(scConfig.Query, scContext.Item);
if (scConfig.PropertyInfo.PropertyType.IsGenericType)
{
Type outerType = Glass.Mapper.Sc.Utilities.GetGenericOuter(scConfig.PropertyInfo.PropertyType);
if (typeof(IEnumerable<>) == outerType)
{
Type genericType = Utilities.GetGenericArgument(scConfig.PropertyInfo.PropertyType);
Func<IEnumerable<Item>> getItems;
if (scConfig.IsRelative)
{
getItems = () =>
{
try
{
return scContext.Item.Axes.SelectItems(query);
}
catch (Exception ex)
{
throw new MapperException("Failed to perform query {0}".Formatted(query), ex);
}
};
}
else
{
getItems = () =>
{
if (scConfig.UseQueryContext)
{
var conQuery = new Query(query);
var queryContext = new QueryContext(scContext.Item.Database.DataManager);
object obj = conQuery.Execute(queryContext);
var contextArray = obj as QueryContext[];
var context = obj as QueryContext;
if (contextArray == null)
contextArray = new[] { context };
return contextArray.Select(x => scContext.Item.Database.GetItem(x.ID));
}
return scContext.Item.Database.SelectItems(query);
};
}
return Glass.Mapper.Sc.Utilities.CreateGenericType(typeof(ItemEnumerable<>), new[] { genericType }, getItems, scConfig.IsLazy, scConfig.InferType, scContext.Service);
}
throw new NotSupportedException("Generic type not supported {0}. Must be IEnumerable<>.".Formatted(outerType.FullName));
}
{
Item result;
if (scConfig.IsRelative)
{
result = scContext.Item.Axes.SelectSingleItem(query);
}
else
{
result = scContext.Item.Database.SelectSingleItem(query);
}
return scContext.Service.CreateType(scConfig.PropertyInfo.PropertyType, result, scConfig.IsLazy, scConfig.InferType, null);
}
}
}
return null;
}
public override bool CanHandle(AbstractPropertyConfiguration configuration, Context context)
{
return configuration is SitecoreSharedQueryConfiguration;
}
}
And configure the new type mapper in your glass config (mapper and parameters for the constructor):
container.Register(Component.For<AbstractDataMapper>().ImplementedBy<SitecoreSharedQueryTypeMapper>().LifeStyle.Transient);
container.Register(Component.For<IEnumerable<ISitecoreQueryParameter>>().ImplementedBy<List<ItemPathParameter>>().LifeStyle.Transient);
container.Register(Component.For<IEnumerable<ISitecoreQueryParameter>>().ImplementedBy<List<ItemIdParameter>>().LifeStyle.Transient);
container.Register(Component.For<IEnumerable<ISitecoreQueryParameter>>().ImplementedBy<List<ItemIdNoBracketsParameter>>().LifeStyle.Transient);
container.Register(Component.For<IEnumerable<ISitecoreQueryParameter>>().ImplementedBy<List<ItemEscapedPathParameter>>().LifeStyle.Transient);
container.Register(Component.For<IEnumerable<ISitecoreQueryParameter>>().ImplementedBy<List<ItemDateNowParameter>>().LifeStyle.Transient);
You can then simply change the SitecoreQuery attribute on your model to SitecoreSharedQuery:
[SitecoreSharedQuery("./*")]
public virtual IEnumerable<YourModel> YourItems { get; set; }
For the children you could either use the shared query mapper and querying the children or create the same classes for a new SitecoreSharedChildren query.
Edit: Added bindings for IEnumerable<ISitecoreQueryParameter> as they are missing and therefor it threw an error.
I am quite new at Android.
So I am a bit confused of working with fragments.
I have found a very great tutorial.
So I have working code. But it is the layout oft a normal activity.
Then I tried to include it into a navigation drawer.
So the list view with data will only be shown when the menu item has been selected.
On the fragment View there is a never ending loading Dialog.
While debugging I have figured out that the code loads still the data and inserts it into feedItems.
So feedItems is filled correctly.
Now after listAdapter.notifyDataSetChanged() there happens nothing.
So here that is my code:
public class FragmentNews extends ListFragment {
private static final String TAG = FragmentNews.class.getSimpleName();
private ListView listView;
private FeedListAdapter listAdapter;
private List<FeedItem> feedItems;
private String URL_FEED = "http://address.com";
public FragmentNews(){}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
loadDataForNews();
}
private void loadDataForNews(){
listView = this.getListView();
feedItems = new ArrayList<FeedItem>();
listAdapter = new FeedListAdapter(getActivity(), feedItems);
listView.setAdapter(listAdapter);
// We first check for cached request
Cache cache = AppController.getInstance().getRequestQueue().getCache();
Entry entry = cache.get(URL_FEED);
if (entry != null) {
// fetch the data from cache
try {
String data = new String(entry.data, "UTF-8");
try {
parseJsonFeed(new JSONObject(data));
} catch (JSONException e) {
e.printStackTrace();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
} else {
// making fresh volley request and getting json
JsonObjectRequest jsonReq = new JsonObjectRequest(Method.GET,
URL_FEED, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
VolleyLog.d(TAG, "Response: " + response.toString());
if (response != null) {
parseJsonFeed(response);
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
// Adding request to volley request queue
AppController.getInstance().addToRequestQueue(jsonReq);
}
}
// List View Feed
private void parseJsonFeed(JSONObject response) {
try {
JSONArray feedArray = response.getJSONArray("feed");
for (int i = 0; i < feedArray.length(); i++) {
JSONObject feedObj = (JSONObject) feedArray.get(i);
FeedItem item = new FeedItem();
item.setId(feedObj.getInt("id"));
item.setName(feedObj.getString("name"));
// Image might be null sometimes
String image = feedObj.isNull("image") ? null : feedObj
.getString("image");
item.setImge(image);
item.setStatus(feedObj.getString("status"));
item.setProfilePic(feedObj.getString("profilePic"));
item.setTimeStamp(feedObj.getString("timeStamp"));
// url might be null sometimes
String feedUrl = feedObj.isNull("url") ? null : feedObj
.getString("url");
item.setUrl(feedUrl);
feedItems.add(item);
}
// notify data changes to list adapater
listAdapter.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
}
Can the problem be that the inflater of listAdapter is null?
Thanks for help!
Sometimes listAdapter.notifyDataSetChanged() does not work properly.
Try removing
listAdapter = new FeedListAdapter(getActivity(), feedItems);
listView.setAdapter(listAdapter);
from loadDataForNews() and adding in
place of listAdapter.notifyDataSetChanged();
When I manually archive an item which is referenced by other items Sitecore popup dialog box with Actions – how to handle the links.
If the item is configured for automatic archiving with “Set Archive Date” and it is archived seems that Sitecore is choosing by default “Leave Links” action, so all links to the archived item will be broken.
How/Where could I hooked up in order to stop archiving of item (scheduled archiving) which is referenced by other items? I would like to stop archiving and create some rapport that that archiving was not successful.
In order to prevent Sitecore from archiving linked items, you need to overrider 2 classes.
First of them is ArchiveItem so it's checking whether item is linked before archiving it:
namespace My.Assembly.And.Namespace
{
public class MyArchiveItem : Sitecore.Tasks.ArchiveItem
{
public MyArchiveItem(System.DateTime taskDate) : base(taskDate)
{
}
public override void Execute()
{
using (new Sitecore.SecurityModel.SecurityDisabler())
{
lock (SyncRoot)
{
Sitecore.Data.Items.Item item = GetItem();
if (item != null && HasLink(Sitecore.Globals.LinkDatabase, item))
{
Sitecore.Diagnostics.Log.Error(string.Format(
"Item {0} or one of its descendants are linked from other items. "
+ "Remove link before scheduling archive.", item.Paths.FullPath), this);
// uncomment next line if you don't want to retry archiving attempt
//Sitecore.Globals.TaskDatabase.Remove(this);
return;
}
}
}
base.Execute();
}
private static bool HasLink(Sitecore.Links.LinkDatabase linkDatabase, Sitecore.Data.Items.Item item)
{
Sitecore.Links.ItemLink[] referrers = linkDatabase.GetReferrers(item);
if (referrers.Length > 0)
{
if (referrers.Any(link => link.SourceFieldID != Sitecore.FieldIDs.Source))
{
return true;
}
}
foreach (Sitecore.Data.Items.Item item2 in item.Children)
{
if (HasLink(linkDatabase, item2))
{
return true;
}
}
return false;
}
}
}
Second class which you need to override is SqlServerTaskDatabase so it schedules the overriden MyArchiveItem task instead of the original Sitecore ArchiveItem:
namespace My.Assembly.And.Namespace
{
public class MySqlServerTaskDatabase : Sitecore.Data.SqlServer.SqlServerTaskDatabase
{
public MySqlServerTaskDatabase(string connectionString) : base(connectionString)
{
}
public override void UpdateItemTask(Sitecore.Tasks.Task task, bool insertIfNotFound)
{
Sitecore.Data.Sql.SqlBatch batch = new Sitecore.Data.Sql.SqlBatch(true);
BindTaskData(task, batch);
string sql = GetUpdateSql() +
" WHERE [ItemID] = #itemID AND [Database] = #databaseName AND [taskType] = #taskType";
batch.AddSql(sql);
if (insertIfNotFound)
{
AddInsertTask(batch, true);
}
batch.Execute(ConnectionString);
}
protected new virtual void BindTaskData(Sitecore.Tasks.Task task,
Sitecore.Data.Sql.SqlBatch batch)
{
System.DateTime taskDate = task.TaskDate;
if (taskDate == System.DateTime.MinValue)
{
taskDate = (System.DateTime)System.Data.SqlTypes.SqlDateTime.MinValue;
}
batch.AddParameter("taskID", task.ID);
batch.AddParameter("nextRun", taskDate);
if (task is Sitecore.Tasks.ArchiveItem)
{
batch.AddParameter("taskType",
Sitecore.Reflection.ReflectionUtil.GetTypeString(typeof(MyArchiveItem)));
}
else
{
batch.AddParameter("taskType", ReflectionUtil.GetTypeString(task.GetType()));
}
batch.AddParameter("parameters", task.Parameters);
batch.AddParameter("recurrence", task.RecurrencePattern);
batch.AddParameter("itemID", task.ItemID);
batch.AddParameter("databaseName", task.DatabaseName);
if (string.IsNullOrEmpty(task.InstanceName))
{
batch.AddParameter("instanceName", System.DBNull.Value);
}
else
{
batch.AddParameter("instanceName", task.InstanceName);
}
}
}
}
The last thing you need to do is to update Sitecore config to point at MySqlServerTaskDatabase:
<TaskDatabase type="My.Assembly.And.Namespace.MySqlServerTaskDatabase, My.Assembly">
<param connectionStringName="core"/>
</TaskDatabase>
The information about failed archiving attempt will be stored in log files. You may want to update this part to store it in your custom reports.
Below goes additional information which is not necessary for your original problem to work.
You can also hook before the schedule is set as described below to inform user that the item won't be archived.
First create the class that will override ArchiveDateForm class:
namespace My.Assembly.And.Namespace
{
public class MyArchiveDateForm
: Sitecore.Shell.Applications.Dialogs.ArchiveDate.ArchiveDateForm
{
protected override bool SetItemArchiveDate
(Sitecore.Data.Items.Item item, string value)
{
if (HasLink(Sitecore.Globals.LinkDatabase, item))
{
Sitecore.Web.UI.Sheer.SheerResponse.Alert(
"Item or one of its descendants are linked from other items. "
+ "Remove link before scheduling archive.", new string[0]);
return false;
}
return base.SetItemArchiveDate(item, value);
}
private static bool HasLink(Sitecore.Links.LinkDatabase linkDatabase,
Sitecore.Data.Items.Item item)
{
Sitecore.Links.ItemLink[] referrers =
linkDatabase.GetReferrers(item);
if (referrers.Length > 0)
{
if (referrers.Any(
link => link.SourceFieldID != Sitecore.FieldIDs.Source))
{
return true;
}
}
foreach (Sitecore.Data.Items.Item item2 in item.Children)
{
if (HasLink(linkDatabase, item2))
{
return true;
}
}
return false;
}
}
}
Then find the file /sitecore/shell/applications/dialogs/archive item/archive date.xml. Change the 6th line to point at the new class:
<CodeBeside Type="My.Assembly.And.Namespace.MyArchiveDateForm,My.Assembly" />
And that's it. Whenever one will try to schedule archiving of an linked item, Sitecore will display information that the item cannot be archived.
I have a class (Not (DAL)) that get's data from DB and give it to me in required format(in specific class format).
Now i need to write a unit test case, but TestContext Data row always return me single row.
I want to fill TestContext by my stored procedure. Please tell me how can i specify stored procedure name.
Thanks in advance.
Here Is Code.
public static List<TextValueField> ExternalDataGet(int providerId)

I want to fill TestContext by my stored procedure. Please tell me how can i specify stored procedure name.
This should handle your request.
