Hi,
I've been struggling a bit with the radgridview since the Itemssource can be updated somewhere else, but the thing is, it's the full collection that gets updated, and when this happens, the entire sorting/filter is lost.
I assume I have to make sure that only one specific item in the collection gets modified, but not quite sure what the best approach is here, since the collection is filled with Telerik DataAccess entities and if I'm not wrong there is not Inotifyproperty on the entities.

I'm using a RadToolBar in an Excel task pane. When the task pane is sized to move controls to the overflow, the overflow button will enable but clicking the overflow button will not display the controls. I've further narrowed the problem to when the WPF user control is converted to an INativeControlHandle and back before adding it to the task pane.
I've built a sample project to demonstrate the problem. The sample also includes a regular WPF ToolBar which does not have the same problem. (remove the .jpg extension from the .zip file)
Note that the same code hosted in a Word addin will function correctly as will a generic WinForms application.
Any advice would be appreciated.

Hi Forum,
I'm trying to trying to open Excel and populate the worksheet with data without actually saving a *.xlsx a file first from WPF. When the user clicks on save within Excel, he/she should be prompted with file location selection prompt as no file exists.
The closest example I've found so far is Telerik's xlsxformatprovider, which is not exactly what i'm looking for.

Does anyone know how to do this?

I have added a button to some cell edit template. When I click on it, I open a file dialog to select some file. However, as soon as I click on the button, the edit mode is left. How can I stay in the edit mode?

I have to react to a key-down-event in a datacell of a GridView. So in XAML I have defined the following:
<telerik:GridViewDataColumn Header="Bezeichnung" DataMemberBinding="{Binding Bezeichnung}"> <i:Interaction.Triggers> <i:EventTrigger EventName="KeyDown"> <GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}, Path=DataContext.OpenNachschlagText}" /> </i:EventTrigger> </i:Interaction.Triggers></telerik:GridViewDataColumn>
With this snippet of code there are no errors in the output-console (no "DataContext.OpenNachschlagText not found" or so). But my ICommand (RelayCommand in my case) is not called when I press a key on the keyboard.
What is wrong or better: how can I react on a key, for example the F5 key?
Thanks in advance

Hello,
When I update a named range programmatically I am forced to remove the name and re-add it with the updated value. This is fine as a workaround but any cells that referred to the name can have strange visuals depending on the new value. For example, I have a named range 'Test' in which RefersTo ​is '=1'. I set A1 to be =Test and it displays 1 as expected. If I remove the name and re-add a new name 'Test' with RefersTo '=1000', A1 will extend into the neighboring cell.

Hi,
We are still using .net version 3.5 and I need to use a RichTextBox that supports the spell checker for this version. Since I have purchased my license recently, I do not see that version in the current downloads. Is there a way for me to obtain a version that will work in 3.5?
Thanks in advance,
Laura
