Telerik WPF RadGridView DataTemplate button binding-CodePudding

I want to bind a Button click event to my viewModel

Currently I have the following.

 <UserControl.Resources>
        <vm:PlannerOverviewViewModel x:Key="ViewModel"/>
    </UserControl.Resources>

 <telerik:RadGridView x:Name="ViewResponsibleOrganisationUnits" Grid.Row="1" ShowGroupPanel="False" CanUserFreezeColumns="False" FrozenColumnsSplitterVisibility="Collapsed"

The binding to the viewmodel is not working Command="{Binding Path=DeleteOrganisationUnitCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type vm:PlannerOverviewViewModel}} }"

ViewModel

   public IDelegateCommand DeleteOrganisationUnitCommand
        {
            get
            {
                return deleteOrganisationUnitCommand ?? (deleteOrganisationUnitCommand = DelegateCommand.CreateAsync(ExecuteDeleteOrganisationUnitCommandAsync, CanExecuteDeleteOrganisationUnitCommand));
            }
        }

Any help would be appriciated

In your case you can do this:

Command="{Binding Path=DeleteOrganisationUnitCommand, Source={StaticResource ViewModel}, Mode=OneWay}"

CodePudding user response：

PlannerOverviewViewModel is not a visual - but RadGridView is.

The following should work if DeleteOrganisationUnitCommand is a property of the DataContext of the RadGridView, i.e. if DeleteOrganisationUnitCommand is defined in the same class as ResponsibleForOrganisationUnits:

Command="{Binding Path=DataContext.DeleteOrganisationUnitCommand,
    RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}} }"
