Hi guys,

I've got a weird problem:

When EnableRowVirtualization = true 

I have a grid with lots of rows like > 100 and I click on the first 10 rows or so the click event of the templated checkbox is handled perfectly. When I scroll down and click again on the checkbox, the click event is not fired.


When EnableRowVirtualization = false

Everything just works.

I hope you can help! (using build: 2013.2.611.1050)


Greetings Edward

Hi Edward,

I tried to reproduce the issue using the provided details but I was not able to. Attached you can find the project used for the test. Are you able to get the problem on it?

Hi Vera

Yes, I see that your example just works.

After extra investigation it appears it is not a click issue but a 'going in edit mode' thing.

Anyway after the change (EditTriggers="CellClick") below our software also works.

Thanks!

<telerik:GridViewDataColumn  UniqueName="checkColumn" IsReadOnly="True" EditTriggers="CellClick">
    <telerik:GridViewDataColumn.Header>
        <CheckBox x:Name="chkSelectAll" Margin="0" Padding="0" VerticalAlignment="Center" IsChecked="True" HorizontalAlignment="Center" Click="ToggleCheckBoxItemsClick"/>
    </telerik:GridViewDataColumn.Header>
 
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
            <CheckBox Content="" IsChecked="{Binding Mode=TwoWay, Path=Checked}" Click="ChkDetailItemClick"  VerticalAlignment="Center" HorizontalAlignment="Center" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>
