Hello,

I attached event handler for GridViewRow Selected event by eventSetter.
But i getting "Handler type is not valid" exception.


void Row_Selected(object sender, RoutedEventArgs e){} 
<Style TargetType="telerik:GridViewRow">  
     <EventSetter Event="Selected" Handler="Row_Selected"/>  
</Style> 
What should be the right handler type for this event?

Basicly what I'm trying to do is after the data is loaded to set programaticly the second colomn of Grid to current and in edit mode.
Additionaly on arrow navigartion Up/Down current cell should be updated to the up/down cell in the same colomn and always current cell should be in edit mode.

Thank you

Hello masha reznik,

By default it is not possible to have a cell in edit mode and navigate with the keyboard arrow keys since the editor will steal all keyboard events. To be able to move the current cell you should first commit the edit by pressing the Enter key. Once the value is committed you will be able to navigate through the cells.

I have also implemented the functionality that you have requested in a sample project which is attached to this post. Hope it helps.

Thank you Milan for your solution. But i have some strange behavior,
excuting after 

Grid.CommitEdit();
Grid.ItemsGenerator.ContainerFromIndex(rowIndex)
and 
Grid.ItemContainerGenerator.ContainerFromItem(item)
returns null for any index and item.

So thats leeds to exception on second excution of 

 

SetInEditMode

I found out what was the cause of this behavior.
I had a SortDescriptor on another column, i found a work around for this, but  i think you have a bug.

thanks anyway

Hello masha reznik,

Currently this is expected behavior since all items will be recreated when "Grid.CommitEdit();" is called. We are working on improving this behavior but for the time being you could just use a dispatcher to execute the code after CommitEdit.

Thank you for your feedback.


All the best,
