I am using WebDataTree to display menu like below:
+First Node
+first childNode
+Second Node
+Second childNode
+Third Node
+Third childNode
From the above webdataTree menu, how can I set "+ First Node" as selected (default selected) when the page loads?
Thanks
I achieved this by the below code:
protected void WebDataTree1_PreRender(object sender, EventArgs e)
{
foreach (var item in WebDataTree1.AllNodes)
{
DataTreeNode treeNode = (DataTreeNode)item;
if (treeNode.Text.Equals("Chocolate")) {
treeNode.Selected = true;
WebDataTree1.SelectedNodes.Add(treeNode);
}
}
}

How to make first row of combobox not-selectable? (https://learn.microsoft.com/en-us/uwp/api/Windows.UI.Xaml.Controls.ComboBox?view=winrt-19041)
Combox first row not selectable
You could detect DropDownOpened event and find the fist item with ContainerFromIndex then disable it like the following. Because Combobox dropdown is lazy load, so we need add the task delay in DropDownOpened event.
private async void MyCb_DropDownOpened(object sender, object e)
{
await Task.Delay(100);
var item = MyCb.ContainerFromIndex(0) as ComboBoxItem;
if (item != null)
{
item.IsEnabled = false;
}
}
Is it possible to get __Rendering control's template field value on content item?
Especially, I'd like to get "Data Source" field value defined in control on page item, like below screenshot.
As shown in screenshot, I have some controls in page item and I'd like to get control's "Data Source" field value.
I used this code and I could list all controls using on the page item. But, I don't know how to get the control's browsed data-source information on the page.
public RenderingReference[] GetListOfSublayouts(string itemId, Item targetItem)
{
RenderingReference[] renderings = null;
if (Sitecore.Data.ID.IsID(itemId))
{
renderings = targetItem.Visualization.GetRenderings(Sitecore.Context.Device, true);
}
return renderings;
}
public List<RenderingItem> GetListOfDataSource(RenderingReference[] renderings)
{
List<RenderingItem> ListOfDataSource = new List<RenderingItem>();
foreach (RenderingReference rendering in renderings)
{
if (!String.IsNullOrEmpty(rendering.Settings.DataSource))
{
ListOfDataSource.Add(rendering.RenderingItem);
}
}
return ListOfDataSource;
}
RenderingReference[] renderings = GetListOfSublayouts(targetItem.ID.ToString(), targetItem);
List<RenderingItem> ListOfDataSource = GetListOfDataSource(renderings);
This is exactly what I wanted.
Perfectly working!!!!!!
public IEnumerable<string> GetDatasourceValue(Item targetItem)
{
List<string> uniqueDatasourceValues = new List<string>();
Sitecore.Layouts.RenderingReference[] renderings = GetListOfSublayouts(targetItem.ID.ToString(), targetItem);
foreach (var rendering in renderings)
{
if (!uniqueDatasourceValues.Contains(rendering.Settings.DataSource))
uniqueDatasourceValues.Add(rendering.Settings.DataSource);
}
return uniqueDatasourceValues;
}
}
Here is a blog post that can help: Using the Data Source Field with Sitecore Sublayouts
Here's the relevant code you can call from within a single control:
private Item _dataSource = null;
public Item DataSource
{
get
{
if (_dataSource == null)
if(Parent is Sublayout)
_dataSource = Sitecore.Context.Database.GetItem(((Sublayout)Parent).DataSource);
return _dataSource;
}
}
Accesing the DataSource property defined above will give you the item that is assigned as the Data Source from the CMS.
How do i create a Field value for a Particular Item in a Particular Language? I have an Excel that has all the item Names inside the RootItem .These Items exist in a en-US language Already. i need add values for a particular field for other languages.. Like en-GB, nl-NL, it-IT.
I have a List like
ItemName Language Translation
TestItem en-GB Hello
TestItem nl-NL Hallo
and so on..
The only problem is, when i do item.Add, it creates a new item rather than adding the value to the existing item. How can i handle this?
My code is as follows:
foreach (DataRow row in dt.Rows)
{
Language language = Language.Parse(languageId);
var rootItem = currentDatabase.GetItem(RootItemPath, language);
var item = rootItem.Add(itemName, templateItem);
if (item != null)
{
item.Fields.ReadAll();
item.Editing.BeginEdit();
try
{
//Add values for the fields
item.Fields["Translation"].Value = strTranslationValue;
}
catch (Exception)
{
item.Editing.EndEdit();
}
}
}
Try This:
var rootItem = currentDatabase.GetItem(RootItemPath);
foreach (DataRow row in dt.Rows)
{
Language language = Language.Parse(languageId);
var itemInCurrentLanguage = rootItem.Children.Where(i=>i.Name == itemName).FirstOrDefault();
if(itemInCurrentLanguage == null){
itemInCurrentLanguage = rootItem.Add(itemName, templateItem);
}
var itemInDestinationLanguage = currentDatabase.GetItem(itemInCurrentLanguage.ID, language );
if (itemInDestinationLanguage != null)
{
itemInDestinationLanguage.Fields.ReadAll();
itemInDestinationLanguage.Editing.BeginEdit();
try
{
//Add values for the fields
itemInDestinationLanguage.Fields["Translation"].Value = strTranslationValue;
}
catch (Exception)
{
//Log any error
}
finally
{
itemInDestinationLanguage.Editing.EndEdit();
}
}
}
You need to switch the language before you get the root item:
using (new LanguageSwitcher(language))
{
var rootItem = currentDatabase.GetItem(RootItemPath);
var item = rootItem.Add(selectedItem.Name, CommunityProjectTemplateId);
// Add new item here...
}
Does anyone know how to get a list of all the items protected (and unprotected them after) in sitecore?
I've googled around but I didn't find any relevant results.
Thanks in advance
This is what I have so far...
var homeItem = Sitecore.Context.Database.GetItem(Sitecore.Context.Site.StartPath);
foreach (Item item in homeItem.Children)
{
if (item.Locking.IsLocked())
{
//to do
}
}
Unfortunately the item.Locking.IsLocked is not returning if the item is protected or not.
When you press protect or unprotect item this command is called:
item:togglereadonly
This is the part of the method who protect or unprotect item:
public override void Execute(CommandContext context)
{
if (context.Items.Length != 1)
return;
Item obj = context.Items[0];
obj.Editing.BeginEdit();
obj.Appearance.ReadOnly = !obj.Appearance.ReadOnly;
obj.Editing.EndEdit();
Log.Audit((object) this, "Toggle read only: {0}, value: {1}", AuditFormatter.FormatItem(obj), MainUtil.BoolToString(obj.Appearance.ReadOnly));
}
Found the solution
var homeItem = Sitecore.Context.Database.GetItem(Sitecore.Context.Site.StartPath);
foreach (Item item in homeItem.Children)
{
if (item.Appearance.ReadOnly)
{
//stuff here
}
}
Cheers
I have a simple app, in one activity I take name and date of birth. I store it in the database. and in the main activity I have linearlayout which will show all the names.
When I click on any of the name in the main activity, it should delete that name from the database and also refresh the view.
I am able to delete the entry from database, but my linear layout view is not being updated. Can some one pls help.
public class child extends Activity {
private Intent intent;
private LinearLayout layout;
private LayoutInflater linflater;

//list them on the main screen
final myDBAdapter mydb = new myDBAdapter(getApplicationContext());
mydb.open();
cr = mydb.GetMyData();
if(cr.getCount()>0)
{
cr.moveToFirst();
for (int i=0;i<cr.getCount();i++)
{
cr.moveToPosition(i);
buildList(cr.getString(1),cr.getString(2));
}
}
//Start the login activity which will return the newly added baby name
addBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
startActivityForResult(intent, 1001);
}
});
//Remove all the entries from Database
remBtn.setOnClickListener(new View.OnClickListener() {

for (int i=0;i<cr.getCount();i++)
{

Toast.LENGTH_LONG).show();
mydb.RemoveEntry(cr.getString(1));
cr.moveToPosition(i);
}
}
}
});
mydb.close();
}
private void buildList(final String bname,String bsex)
{
final View customView = linflater.inflate(R.layout.child_view,
null);
TextView tv = (TextView) customView.findViewById(R.id.TextView01);

WHAT IS REQUIRED HERE TO UPDATE THE VIEW???

else
{

Toast.LENGTH_LONG).show();
}
}
});
layout.addView(customView);
}
#Override

if(requestCode == 1001)
{
if(resultCode == RESULT_OK)
{
Bundle extras = data.getExtras();
buildList(extras.getString("bname"),extras.getString("bsex"));
}
}
}
}
Hmm I'm also trying to get this to work, Have you tried looking at maybe refreshing the LinearLayout every say 5 seconds using a game loop? This may prove to be useful as it helped me with my problem http://aubykhan.wordpress.com/2010/04/25/android-game-programming-the-game-loop/
You may also be able to call onCreate(Bundle) function again while this is a terrible terrible way to do this it will work.
