Hi,

I'm currently setting my ItemsSource for my RadGrid to be of type QueryableCollectionView

I also set the selecteditem to be of type IDTO. 

When I use an QueryableCollectionView, by default, SelectedItem is set to the first item in the collection. If I were to use an ObservableCollection, it's completely fine, SelectedItem is empty until an item is selected. May I ask how do I set it so the QueryableCollectionView doesn't set the value by default. 

Hi Team,

I am facing an issue with Ribbonview during design time I can not see the ribbon control.

Scenario:

I have created a user control as a container for my Ribbonview. During design time we need to specify the height of that container user control to more than 250 like 251 in order to see this control during design time.

<telerik:RadGridView.FilterDescriptors>   

     <telerik:CompositeFilterDescriptor LogicalOperator="Or">       

          <telerik:CompositeFilterDescriptor.FilterDescriptors>             

               <telerik:FilterDescriptor Member="Hardcoded" Operator="IsEqualTo" Value="false"/>        

          </telerik:CompositeFilterDescriptor.FilterDescriptors>   

     </telerik:CompositeFilterDescriptor>

</telerik:RadGridView.FilterDescriptors>

When the editor becomes active, the contextualgroup IsActive is set to true and RibbonTab appear visible. When user selects it, it looks like in "before" picture. Everything ok. But when in this time the editor is closed, IsActive is set to false, but no other RibbonTab is automatically selected and in appears like in "after" picture. In the samples, i have not seen any special source code to select to another RibbonTab in this case. What is necessary to do in this case and how to define RibbonTab to be selected when ContextualGroup.IsActive is set to false?

Thanks, Ivo Kovacka

Hi,

I need to hide a RadWindow completely and have tried multiple ways but they do not give the expected result. In fact, I have tried minimizing the window and hiding the icon from the taskbar (but I haven't found such a method in the documentation), or setting the visibility to Hidden but none of those completely hide the Window. How is it possible to hide a window, other than by closing it?

Kind regards,

Alexandre

Check box tick color in GridViewCheckBoxColumn does not react to Expression Dark theme when it is in view mode.

I have a RadComboBox trying out the new AllowMultipleSelection feature but the problem is that it keeps auto-selecting an item in the ItemsSource on first display even though the control was initialized to have nothing selected and the user never had a chance to select anything. The SelectionChanged event doesn't capture this first stealth selection so all my viewmodel selection state is screwed up.

Is there a way to stop it?

In a pivot grid,if I have a numeric field in the "Row Labels", I can use the "Select step" feature to group the values. However, how do I supply a min and a max like I can do in Excel's "Group by" feature? The reason I want this is that my data has some outliers and I want to collapse them into a single group like "> 100" or "< 0" instead of excluding them.

Thanks

Hey,

Am I able to set some spacing or border/brush line between only main tasks?

Hey, 

In my scenario I have one ScheduleView which takes data from 2 places:

a) Google Calandar (iCal)

b) my own database.

I would like to disable delete option for appointments from Google, but allow to delete from my Database.

Is there any chance for me?
