Hi,

I have a gridview using the </gridView:RadGridView.RowDetailsTemplate> to display finer details about the item in the grid row. This works fine. inside this template I also have a button which has an attached command:

<Button Margin="2,2,2,2" Padding="5,5,5,5" Style="{DynamicResource SimpleButton}" HorizontalAlignment="Stretch" VerticalAlignment="Bottom"
                                    x:Name="DeleteTaskButton" FontWeight="Normal" Foreground="#505050" FontSize="14" FontFamily="Corbel"
                                    Content="Delete Task Schedule"
                                    commands:Click.Command="{Binding DeleteTaskCommand}"
                                    commands:Click.CommandParameter="{Binding Id}"/>

Here I can pass the Id of the Item to my backing ViewModel and remove from the collection. However, this currently doesn't work because the DelegateCommand is part of the ViewModel NOT the object being rendered by the DataTemplate. Obviously I could add the command to the object but I don't like it as it gets quite messy, my base object has already had INotifyPropertyChanged added to it. Ideally what I would like is a way have the button command in my ViewModel picking up the command from the DataTemplate, and also if possible I would like to be able to retrieve the SelectedIndex of the GridView.

Thanks, Mark

Hello Mark Westwood,

The element loaded from the RowDetails DataTemplate gets the respective data item (row) as its DataContext. Do this data item should have the command, I guess.

We cannot think of another way to handle your command apart from adding it to your details object. DataTemplates are part of the WPF Framework and we have no control over their behavior. In case you have an idea about how to overcome this limitation, we would be glad to hear it and we might consider implementing it for a future version.

Greetings,
