Hi All,

I am using RadGridView in WPF application with MVVM light. In celltemplate i am able to bind relay command for button but i am getting null argument on click event.

Sample Code:

<UserControl

                      ..

                       DataContext="{Binding SearchControlVM, Source={StaticResource Locator}}"

</UserControl>

..

 <telerik:RadGridView

  ..
                        <telerik:GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <telerik:RadButton Content="View" Command="{Binding Path=DataContext.ViewCommand,
                                                    RelativeSource={RelativeSource FindAncestor,AncestorType=telerik:RadGridView}}"  />
                                ..

 </telerik:RadGridView>

How to pass argument to MVVMlight relay command. Any help would be appreciated.

 

Thanks,

Prashant

Hello Prashant,

Thank you for the provided code snippet. 

May I ask you to try setting the CommandParameter property of the RadButton? Please, give this a try and let me know how it goes. 

On a side note, you can also check out Telerik's EventToCommandBehavior, which allows for handling an event with a command from the viewmodel.

I hope you find this helpful. Let me know, if I can be of any further assistance.

Hi Vladimir,

Thanks for reply,

CommandParameter and EventToCommandBehavior  really helped me to understand behavior for command binding but unfortunately not working with MVVM light.

But i tried below code and that worked with my project architecture,

   <telerik:GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <telerik:RadButton Content=" View" >
                                        <i:Interaction.Triggers>
                                            <i:EventTrigger EventName="Click">
                                                <glevnt2cmd:EventToCommand Command="{Binding Path=DataContext.ViewAssetCommand,RelativeSource={RelativeSource FindAncestor,AncestorType=telerik:RadGridView}}" 
                                                                       PassEventArgsToCommand ="True"/>
                                            </i:EventTrigger>
                                        </i:Interaction.Triggers>
                                    </telerik:RadButton>
                                </DataTemplate>
                            </telerik:GridViewColumn.CellTemplate>

Really appreciate your help,

Prashant
