Tab Key Deselects my selected rows

[Chet Watkins]

I have a gridview that is using the selection checkbox column. The problem we are running into is that if someones selects rows with the checkboxes, then hits tab, the tab key will cause the row in focus to check (if not checked) and unselect all the other rows. Is there a way to disable this from happening?

Hello Chet Watkins,

First of all, please excuse me for the delay.
The default behavior of the Tab key is to perform the commands RadGridViewCommands.MoveNext and RadGridViewCommands.SelectCurrentItem. The result is that all selected items are deselected, leaving only the CurrentItem selected. In order to change that you need to create additional class in our project - CustomKeyboardCommandProvider and to predefine that behavior as follows:

public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
        {
            List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();
            if (key == Key.Tab)
            {
                commandsToExecute.Remove(RadGridViewCommands.SelectCurrentItem);
            }
            return commandsToExecute;
        }

Furthermore, you need to set the Property of the grid - IsSynchronizedWithCurrentItem to "false".
I am sending you a sample project so that you can see and test the proposed solution.
