I want to merge between my code that contains the Web service and the code of WindowsPhoneDataBound Application.Is it possible? and how?
My Code:
private void button1_Click(object sender, RoutedEventArgs e)
{
Uri url = new Uri("http://www.google.com/ig/api?weather=" + textBoxVille.Text, UriKind.Absolute);
WebClient client = new WebClient();
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
client.DownloadStringAsync(url);
}
void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
StringReader stream = new StringReader(e.Result);
XmlReader reader = XmlReader.Create(stream);
reader.MoveToContent();
while (reader.Read())
{
switch (reader.Name)
{
case ("day_of_week"):
{
listBox1.Items.Add(new ListBoxItem()
{
Content = reader.GetAttribute("data")
});
} break;
case ("low"):
{
listBox1.Items.Add(new ListBoxItem()
{
Content = reader.GetAttribute("data")
});
} break;
case ("high"):
{
listBox1.Items.Add(new ListBoxItem()
{
Content = reader.GetAttribute("data")
});
} break;
case ("icon"):
{
listBox1.Items.Add(new ListBoxItem()
{
Content = reader.GetAttribute("data")
});
} break;
case ("condition"):
{
listBox1.Items.Add(new ListBoxItem()
{
Content = reader.GetAttribute("data")
});
} break;
case ("weather"):
break;
}
}
reader.Close();
}
}
Of course it is possible with the help of data binding and observable collections. Instead of adding new list box items every time you get a new element, you can use an ObservableCollection. Set the data source of the listbox to the observable collection.
The benefit of using ObservableCollection is that whenever you add or remove an element from your collection, your listbox will automatically reflect that. So no need to manually add or remove listboxItems. If your listboxItem has custom layout, then you can create a dataTemplate and bind data to the elements which needs to be displayed in the listboxItem.

I'm having an issue changing the workflow state for an item programmatically. The state isn't being changed no matter what I do to the field. I've tried using (new SecurityDisabler()){} and putting the item in editing mode then changing the field manually. I've noticed that the item itself has the Lock set to <r />, could this be causing an issue?
Here is some sample code of what I've tried to do:
[HttpPost]
[MultipleButton(Name = "action", Argument = "Submit")]
public ActionResult Submit(LoI model)
{
if (model.Submitted || !model.Signed)
{
return Redirect("/Profile/LoI");
}
ModifyCandidateInfo(model, true);
Session["message"] = Translate.Text("loi-submitted-message");
Session["messageClass"] = "success";
return Redirect("/Profile/LoI");
}
private static void ModifyCandidateInfo(LoI model, bool isSubmission)
{
using (new SecurityDisabler())
{
var candidateFolder = CBUtility.GetCandidateFolder();
var loi= candidateFolder.GetChildren().SingleOrDefault(loi => loi.TemplateID == LoITemplateId);
if (loi == null) return;
loi.Editing.BeginEdit();
EditFields(loi, model);
EditChildren(loi, model);
//Send emails upon submission
if (isSubmission)
{
loi.ExecuteCommand("Submit",
loi.Name + " submitted for " + model.CandidateName);
using (new SecurityDisabler())
{
loi.Editing.BeginEdit();
loi.Fields["__Workflow state"].Value = "{F352B651-341B-4CCF-89FE-BD77F5E4D540}";
loi.Editing.EndEdit();
}
}
loi.Editing.EndEdit();
}
}
I initalized the item's workflow with the following function:
public static void InitializeWorkflow(Item item, ID workflowId)
{
item.Editing.BeginEdit();
var workflow =
item.Database.WorkflowProvider.GetWorkflow(workflowId.ToString());
workflow.Start(item);
item.Editing.EndEdit();
}
The item starts at the default drafting state and executed a "Submit" command that fires off emails. Through the Sitecore UI if I hit submit it'll go to the next workflow state but not programmatically when I fire off the ExecuteCommand function. Below you'll find the ExecuteCommand function.
public static WorkflowResult ExecuteCommand(this Item item, string commandName, string comment)
{
using (new SecurityDisabler())
{
var workflow = item.Database.WorkflowProvider.GetWorkflow(item);
if (workflow == null)
{
return new WorkflowResult(false, "No workflow assigned to item");
}
var command = workflow.GetCommands(item[FieldIDs.WorkflowState])
.FirstOrDefault(c => c.DisplayName == commandName);
return command == null
? new WorkflowResult(false, "Workflow command not found")
: workflow.Execute(command.CommandID, item, comment, false);
}
}
The command fires off fine and the emails are sent but I can't figure out why the state won't change. Could someone provide me with other suggestions or a solution?
Am I reading the workflow state id correctly? I'm using the item ID for the workflow state.
I think your code is really similar to my implementation. This is my code's background.
All items have the same workflow named "WF" and it has three workflow states (Working, Awaiting Approval, and Approved). One page-item having "WF" has some rendering items and those datasource items. Suppose a content editor is ready to submit and approve the item with its related items. By hitting the "Submit" and "Approval" button in the page, all page-item's related items have the same workflow state as the page-item's one.
Most code are from Marek Musielak and this code is perfectly working in my side.
public class UpdateWorkflowState
{
// List all controls in page item
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;
}
// Return all datasource defined on one item
public IEnumerable<string> GetDatasourceValue(WorkflowPipelineArgs args, Item targetItem)
{
List<string> uniqueDatasourceValues = new List<string>();
Sitecore.Layouts.RenderingReference[] renderings = GetListOfSublayouts(targetItem.ID.ToString(), targetItem);
LayoutField layoutField = new LayoutField(targetItem.Fields[Sitecore.FieldIDs.FinalLayoutField]);
LayoutDefinition layoutDefinition = LayoutDefinition.Parse(layoutField.Value);
DeviceDefinition deviceDefinition = layoutDefinition.GetDevice(Sitecore.Context.Device.ID.ToString());
foreach (var rendering in renderings)
{
if (!uniqueDatasourceValues.Contains(rendering.Settings.DataSource))
uniqueDatasourceValues.Add(rendering.Settings.DataSource);
}
return uniqueDatasourceValues;
}
// Check workflow state and update state
public WorkflowResult ChangeWorkflowState(Item item, ID workflowStateId)
{
using (new EditContext(item))
{
item[FieldIDs.WorkflowState] = workflowStateId.ToString();
}
Sitecore.Layouts.RenderingReference[] renderings = GetListOfSublayouts(item.ID.ToString(), item);
return new WorkflowResult(true, "OK", workflowStateId);
}
// Verify workflow state and update workflow state
public WorkflowResult ChangeWorkflowState(Item item, string workflowStateName)
{
IWorkflow workflow = item.Database.WorkflowProvider.GetWorkflow(item);
if (workflow == null)
{
return new WorkflowResult(false, "No workflow assigned to item");
}
WorkflowState newState = workflow.GetStates().FirstOrDefault(state => state.DisplayName == workflowStateName);
if (newState == null)
{
return new WorkflowResult(false, "Cannot find workflow state " + workflowStateName);
}
unlockItem(newState, item);
return ChangeWorkflowState(item, ID.Parse(newState.StateID));
}
// Unlock the item when it is on FinalState
public void unlockItem(WorkflowState newState, Item item)
{
if (newState.FinalState && item.Locking.IsLocked())
{
using (new EditContext(item, false, false))
{
item["__lock"] = "<r />";
}
}
}
}
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();
I have written code to filter out new XML elements that have been introduced as part of web service enhancements. The transformation seems to work with small XML but as soon as I increase the size its stops working. Using SoapUI, it simply returns a blank response.
Can anyone help? Do i need to alter the code below to handle large XML?
public void Dispose()
{
//clean-up code here.
}
public void Init(HttpApplication context)
{
context.BeginRequest += new EventHandler(context_BeginRequest);
context.PreRequestHandlerExecute += new EventHandler (context_PreRequestHandlerExecute);
}
void context_PreRequestHandlerExecute(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
State state = (State)app.Context.Items["VersionManagerState"];
if (state.ProcessRequest)
{
Stream xslres = Assembly.GetExecutingAssembly().GetManifestResourceStream(string.Concat("TestService.VersionManager.",state.Version, ".xslt"));
if (xslres != null)
{
state.Xsl = new XslCompiledTransform();
state.Xsl.Load(XmlReader.Create(xslres));
app.Context.Response.Filter = new OutputFilterStream(state, app.Context.Response.Filter);
}
}
}
void context_BeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
State state = new State();
app.Context.Items["VersionManagerState"] = state;
if (app.Context.Request.Url.AbsolutePath.EndsWith(".asmx") && app.Request.RequestType == "POST")
{
state.ProcessRequest = true;
app.Context.Request.Filter = new InputFilterStream(state, app.Context.Request.Filter);
}
}
I have tried for days but I couldn't reach any successful result. I need to post images with their information (s.t. created user name).
This is my method;
[HttpPost]
public Task<HttpResponseMessage> PostFile(string createdByName)
{
HttpRequestMessage request = this.Request;
if (!request.Content.IsMimeMultipartContent())
{
throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
}
string root = System.Configuration.ConfigurationSettings.AppSettings["TempUploadDir"];
var provider = new MultipartFormDataStreamProvider(root);
var task = request.Content.ReadAsMultipartAsync(provider).
ContinueWith<HttpResponseMessage>(o =>
{
AddImages(provider.BodyPartFileNames);
string file1 = provider.BodyPartFileNames.First().Value;
// this is the file name on the server where the file was saved
return new HttpResponseMessage()
{
Content = new StringContent("File uploaded.")
};
}
);
return task;
}
And this my TypeFormatterClass which is added global.asax
public class MultiFormDataMediaTypeFormatter : FormUrlEncodedMediaTypeFormatter
{
public MultiFormDataMediaTypeFormatter()
: base()
{
this.SupportedMediaTypes.Add(new MediaTypeHeaderValue("multipart/form-data"));
}
protected override bool CanReadType(Type type)
{
return true;
}
protected override bool CanWriteType(Type type)
{
return false;
}
protected override Task<object> OnReadFromStreamAsync(Type type, Stream stream, HttpContentHeaders contentHeaders, FormatterContext formatterContext)
{
var contents = formatterContext.Request.Content.ReadAsMultipartAsync().Result;
return Task.Factory.StartNew<object>(() =>
{
return new MultiFormKeyValueModel(contents);
});
}
class MultiFormKeyValueModel : IKeyValueModel
{
IEnumerable<HttpContent> _contents;
public MultiFormKeyValueModel(IEnumerable<HttpContent> contents)
{
_contents = contents;
}
public IEnumerable<string> Keys
{
get
{
return _contents.Cast<string>();
}
}
public bool TryGetValue(string key, out object value)
{
value = _contents.FirstDispositionNameOrDefault(key).ReadAsStringAsync().Result;
return true;
}
}
}
When I post images and "createdByName" I can reach images but I couldn't parameters. How can I do this?
Thank you.
To get your createdByName field, inside your ContinueWith :
var parts = o.Result;
HttpContent namePart = parts.FirstDispositionNameOrDefault("createdByName");
if (namePart == null)
{
throw new HttpResponseException(HttpStatusCode.BadRequest);
}
string name = namePart.ReadAsStringAsync().Result;
For a more detailed example, see :

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)
{
return ListFactory<TextValueField>.Create(Keys.QAT, "[stats].[GetExternalDataV2]", new object[] { providerId }, TextValueField.Factory);
}
public static List<T> Create(string key, string sp, object[] parameters, FactoryDelegate factory)
{
List<T> list = new List<T>();
Database db = DatabaseFactory.CreateDatabase(key);
string connectionString = db.ConnectionStringWithoutCredentials;
using (DbCommand cmd = db.GetStoredProcCommand(sp, parameters))
{
try
{
using (cmd.Connection = db.CreateConnection())
{
cmd.Connection.Open();
cmd.CommandTimeout = 0;
using (DbDataReader reader = cmd.ExecuteReader())
{
try
{
while (reader.Read())
list.Add(factory(reader));
}
finally
{
if (!reader.IsClosed)
reader.Close();
}
}
cmd.Connection.Close();
}
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
throw new DataAccessException(ex, key, connectionString, sp, parameters);
}
finally
{
if (cmd.Connection != null)
if (cmd.Connection.State == ConnectionState.Open)
cmd.Connection.Close();
}
}
return list;
}
I want to fill TestContext by my stored procedure. Please tell me how can i specify stored procedure name.
This should handle your request.
public static List<TextValueField> ExternalDataGet(int providerId, string storedProc = "[stats].[GetExternalDataV2]")
{
return ListFactory<TextValueField>.Create(Keys.QAT, storedProc, new object[] { providerId }, TextValueField.Factory);
}
