DataGridTemplateColumn Event Behavior

[Perry]

I want to have the Checked Event Binded to my RelayCommand in the ViewModel. I try to do this via an behavior but every possible implementation I try isn't working.
Do I miss something?

<grid:DataGridTemplateColumn.CellContentTemplate>
                                        <DataTemplate>
                                        <StackPanel>
                                            <CheckBox IsChecked="{Binding InCollection}">
                                                <interactivity:Interaction.Behaviors>
                                                    <core:EventTriggerBehavior EventName="Checked">
                                                        <core:InvokeCommandAction
                                                            Command="{Binding InCollectionCommand, Mode=OneWay}"
                                                            InputConverter="{StaticResource CheckBoxEventArgsConverter}"/>
                                                    </core:EventTriggerBehavior>
                                                </interactivity:Interaction.Behaviors>
                                            </CheckBox>
                                        </StackPanel>
                                    </DataTemplate>
                                </grid:DataGridTemplateColumn.CellContentTemplate>
                            </grid:DataGridTemplateColumn>

Thank you in advance.

Hi Perry,

Thank you for contacting us.

The problem is that the context of the cell template is the item from the ItemsSource collection, not the ViewModel. You can either define the command in the data item, or you can define the ViewModel as a static resource in order to be able to bind to its properties in the cell template. I have attached a sample project that demonstrates the second scenario.

I hope this helps. Please, let us know if you have further questions.
