Hi,

I am using the last internal build.

I am setting up a combo box using the following xaml:

<telerik:GridViewDataColumn DataMemberBinding="{Binding TrueType.Name}"
    <telerik:GridViewDataColumn.CellEditTemplate> 
        <DataTemplate> 
            <ComboBox SelectedItem="{Binding TrueType}" DisplayMemberPath="Name" ItemsSource="{Binding TrueTypeValues}"/>    
        </DataTemplate> 
    </telerik:GridViewDataColumn.CellEditTemplate> 
</telerik:GridViewDataColumn> 
 

What happens after that is quiet random.  On some computer, the combobox will work fine for a couple of tries.  And on some computer, the combobox simply refuse to open.  We click on it and nothing happens.  We can notice a tiny window that flash for .1 second on the top left corner of the screen when that happens the first time.

Hi,

Do you have such problems if the combo is outside of the grid?

The problem doesn't occure without the grid.

But i tried to create a sample outside of our application and i can't reproduce the problem.  So it might be something in our application that we will need to identify.

That being said, when creating my sample, I identified something else.

1- Drop the combobox, select an item in the combobox.
2- The row in the grid that was behind the selected item in the combobox get selected.

Hello Eric,

I tried to reproduce your problem but unfortunately without success. Could you please send us a small project where the problem can be seen?

Hi,

I've tried to reproduce the problem, but to no avail. You can check the attached sample project for a reference. May I ask you to modify it in order to reproduce the issue and resend it back to me?

Regards,
