Hello Telerik Team,

I Converted code VB to C#. In VB it is alreday tasted & worked perfectly but in C# Rebind is not working properly.

While loading window am setting like below:

  rgvSet.ItemsSource = DataModule.objSets;
  rgvOrders.ItemsSource = DataModule.objOrderList;
  rgvTour.ItemsSource = DataModule.objTourList;
  rgvTruck.ItemsSource = (from p in DataModule.objTruckList where p.Status == DataModule.Cons_Status_Available select p).ToList<clsTruck>();
  rgvTrailer.ItemsSource = (from p in DataModule.objTrailerList where p.Status == DataModule.Cons_Status_Available select p).ToList<clsTrailer>();
        rgvDriver.ItemsSource = (from p in DataModule.objDriverList where p.Status == DataModule.Cons_Status_Available select p).ToList<clsDriver>();

"rgv... " are RadgridView and all List are ObservableCollection. After doing such operation adding/removing/updating in collection am rebinding appropriate grid. Grid which having itemsource as LINQ query will not Rebind but Grid which have collection as Itemsource will rebind correctly.

What could be a reason? any idea?

Thanks...!!!

Customizable Legend

Hello!
Assuming that I have 6 different SeriesMapping in a chart but in the chart's legend I want to show only 4 of them how should I do this??
I've tried to set their LegendLabel to null but this only puts the default "Series x" label in Legend which is not the desired behavior.

Thank you!

DataContext = from i in Enumerable.Range(0, 10)

select new MyObject()

{

ID = i,

Name = String.Format("Name{0}", i)

};

}

public class MyObject

{

public int ID { get; set; }

public string Name { get; set; }

public IEnumerable<MyObject2> Items

{

get

{

return from i in Enumerable.Range(0, 10)

select new MyObject2()

};

}

public class MyObject2

{

public IEnumerable<MyObject2> Items

{

get

return from i in Enumerable.Range(0, 10)

select new MyObject2()

{

x = i

};

}

private void SubGrid_DataLoading(object sender, GridViewDataLoadingEventArgs e)

{

var grid = (GridViewDataControl)sender;

var d = new GridViewTableDefinition();

d.Relation = new PropertyRelation("Items");

grid.TableDefinition.ChildTableDefinitions.Add(d);

grid.AutoGenerateColumns = false;

grid.Columns.Add(new GridViewDataColumn() { DataMemberBinding = new Binding("x") });

}

For the firs time it is child one and then it becomes self-hierarchical. Everything is OK, but in the real programm we use WCF service and MyObject and MyObject2 are DataContracts, and we need to call a WCF service in the get-methods of the Items property.
So, I ask you for help: How could I call the WFC method or maybe there is another way to make such hierarchy.

How do I hide a row?

I try to hide a row that have a specific status, When I do like the code below. the row is not shown, but there is space left "blank" in the grid where the row should be. I also tested with Height=0

private void radGrid_RowLoaded(object sender, RowLoadedEventArgs e)

{

GridViewRow row = e.Row as GridViewRow;

if (row != null)

{

MyClass _MyClass = row.DataContext as MyClass;

if (row != null && _MyClass != null)

{

row.IsExpandable = _MyClass.Category.Equals(5);

}

else

{

row.IsExpandable = false;

}

if (_MyClass.MediaCategory.Equals(5) && _MyClass.Status.Equals(-1))

{

row.Visibility = System.Windows.Visibility.Collapsed;

}

Any suggestions?

Controls / Textboxes within RadTreeItem

Ok, i have a RadTreeView with an Item Source of List<ActivityControl> which is a user control that has a text box, a canvas and a text box in it... my problem is that because the text box is within the RadTreeView whenever i try and click and drag to select text it tries to drag and drop the Selected item!?! this is going to be a pain for users to try and edit text if they cant drag to highlight....

i've uploaded a video to give you an idea!

http://www.screencast.com/users/kevinrhynas/folders/Jing/media/8fb40a9e-c5ce-4c6f-83ba-20054a6d466f

Also on a side note... i pressume that it is the header of each RadTreeItem that sets the "preview" in the draggable bit... how can i set this if i've simply set the "itemsource" to be a list.. as opposed to manually adding these items??
