How to navigate to next item on commit?

[Karl B]

While editing a value I want to be able to tab to the next item in the grid.  Currently this requires two tabs- the first one commits the edit and the second press to navigate. How can I change this behavior?

I am using RenderMode Flat.

I would accept navigating to the next item on Enter key as well as Tab if it makes the solution easier.

Hello Karl,

What I can suggest in order to achieve the desired result is to handle the PreviewKeyDown event of the control in the following manner:

		public void OnPreviewKeyDown(object sender, KeyEventArgs args)
		{
			if (args.Key == Key.Tab)
            {
				this.rpg.CommitEdit();
				(RadPropertyGridCommands.MoveToNext as RoutedUICommand).Execute(null, this.rpg);
				args.Handled = true;
            }
		}

Note that "rpg" refers to the instance of the RadPropertyGrid control. Please let me know whether such an approach would work for you.

This soultion did not work for me. Not only does the commit not happen when I press tab, but the next item in the property grid becomes highlighted but the previous text box still has keyboard focus. 

If it matters my dll version is 2017.2.614

Hi Karl,

Please excuse me for the misunderstanding. The proposed solution will only work when using the Single EditMode.

If you're using the Default EditMode, you can define the handler as follows:

        public void OnPreviewKeyDown(object sender, KeyEventArgs args)
        {
            if (args.Key == Key.Tab)
            {
                (RadPropertyGridCommands.MoveToNext as RoutedUICommand).Execute(null, this.rpg);
                Dispatcher.BeginInvoke(new Action(() =>
                {
                    this.rpg.BeginEdit();
                }), System.Windows.Threading.DispatcherPriority.Input);
                args.Handled = true;
            }
        }

For your convenience, I've prepared a small sample project which demonstrates how to handle both scenarios.

Please have a look and let me know if this provides the desired behavior or if I'm missing something of importance.
