Hi,

When I do the following actions:
1. Add a new row 
2. Start to edit a cell
3. Start to tab to the next cell
then I get the following error message:

Hello,

Is it possible today in the GridView to provide a menu in the column header that will turn on and off summary functions for columns? I can provide a way for my users to do this, but if there is built in support I would like to use it.

We're using the radtreeview and on the Selected event we fire off some asyncronous functionality that changes the underlying tree itemsource. The problem we're having is we're getting a null ref exception at the location below (see stack trace at the bottom).  We've tried previewSelected and get the same result there.  Our current workarond (not ideal) is to do our processing on MouseUp.  It appears that as we've removed the selected item the tree code isn't checking whether this is null.

I can’t get this to work. I can bind items to a listbox in the same way without problem…

 

 

 

<telerik:RadDocking DataContext="{Binding Source={StaticResource CustomerViewModel}}">

 

 

 

 

    <telerik:RadSplitContainer ItemsSource="{Binding Path=Customers}">

 

 

 

 

        <telerik:RadSplitContainer.ItemTemplate>

 

 

 

 

            <DataTemplate>

 

 

 

 

                <telerik:RadPaneGroup >

 

 

 

 

                    <telerik:RadPane Header="{Binding Path=CustomerName}">

 

 

 

 

                    </telerik:RadPane>

 

 

 

 

                </telerik:RadPaneGroup>

 

 

 

 

            </DataTemplate>

 

 

 

 

        </telerik:RadSplitContainer.ItemTemplate>

 

 

 

 

    </telerik:RadSplitContainer>

 

 

 

 

</telerik:RadDocking>

 

Hi,

I was told by Evan Hutnick that you were working on a TreeListView for WPF and that it should be made available in a Beta Release around the Q3 release. I cannot find it anywhere so I was wondering if I've missed something or what the status is on that control?

We have a project where such a control is very important and I would consider replacing the one we have with yours if it was good.

Hello,

I have a Bar chart defined where the user can toggle between 2-D and 3-D.  XCategory labels work great in 2-D, but in 3-D pointmark values are displayed instead of labels.  Is there a way to show pointmark labels instead of values in 3-D?

Hello,

I am trying to dynamically add tabs to a TabControl using code behind where the template used for HeaderTemplate includes bound controls. Everything is working as I expected, except I cannot get the bound data to appear on the tab.

This is my header template:

And this is my TabControl declaration:

Here is my code behind for adding a new tab to the TabControl:

And here is a stripped down version of the object I am trying to bind:

I have tried setting the DataContext of the tab item (as shown), the tab control, and the window itself without any change. Changing the order in which the item's properties are set also had no affect. I know the tempate is being used because if I change the binding to static text, the text is displayed on the tab correctly. What am I missing here?
