Hello All.

I've a GridView with a checkbox column 

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding IsSelected, Mode=TwoWay, UpdateSourceTrigger= PropertyChanged}" .../>


Now it seems the binding is updated only on lost focus (for example, when clicking on another cell/row) and not according to the UpdateSourceTrigger= PropertyChanged.

This is a problem for me, since I've a menu bar which has commands (like delete) which work on the selected rows, and when the menu item is clicked, the Checkbox binding isn't yet updated. Basically you have to select the checkbox, click on the grid outside the checkbox, and only then click on the menu item.Is there indeed a problem here, or am I doing something wrong? Should I simply use GridViewDataColumn with checkbox instead of GridViewCheckBoxColumn?

Yours,
Roee

I have the following code which uses a boolean type converter and your solution isn't updating the value directly without losing focus.

Can you please help?

<telerik:GridViewDataColumn Header="Status" <br>
                                            DataMemberBinding="{Binding IsActive,Converter={StaticResource ActiveInactiveBooleanConverter}}" IsReadOnly="True"><br>
                    <telerik:GridViewDataColumn.CellTemplate><br>
                        <DataTemplate><br>
                            <CheckBox IsChecked="{Binding IsActive, Mode=TwoWay}"<br>
                                      telerik:StyleManager.Theme="Office_Black"></CheckBox><br>
                        </DataTemplate><br>
                    </telerik:GridViewDataColumn.CellTemplate><br>
                </telerik:GridViewDataColumn>

Hello Ronnie,

Thank you for the provided code snippet.

I tried replicating a similar setup in a small sample project but the value of the IsActive property is directly updated at my end.

Could you please have a look at the attached project and let me know if I'm missing something of importance?
