RemovePropertyChildCommand - Grids for WPF Forum

Posted 13 years ago by Mary Fontana - Rudolph Technologies

I have added a command binding for
PropertyGrid.RemovePropertyChildCommand so that I can comfirm the delete of the property child item.

<CommandBinding
Command="{x:Static propgrid:PropertyGrid.RemovePropertyChildCommand}"
Executed="RemovePropertyChild_Executed" />

In my method:
private void RemoveChildProperty_Executed(object sender, ExecutedRoutedEventArgs e)

I can see the item I want to remove in e.Parameter.Value;
But how do you remove the item from the collection holding on to it?

Or is there another way of doing this?

Thanks,
Mary

Hi Mary,

Our default handler in PropertyGrid looks like this:

protected virtual void OnRemovePropertyChild(ExecutedRoutedEventArgs e) {
    if (e == null)
        throw new ArgumentNullException("e");

    if (!this.IsReadOnly) {
        IPropertyDataAccessor propertyDataAccessor = e.Parameter as IPropertyDataAccessor;
        if (propertyDataAccessor != null && propertyDataAccessor.CanRemove) {
            e.Handled = true;
            propertyDataAccessor.Remove();
        }
    }
}

You may want to create a class that derives from PropertyGrid (i.e. MyPropertyGrid) and simply override our OnRemovePropertyChild method. Otherwise, that command will have two handlers, even if one is never called.
