How to set focus to a tab after double-clicking a DataGrid?

If you want to set focus to a control on another tab after double-clicking a row in a DataGrid, do the following:

• Create a handler for the DataGrid's MouseDoubleClick event.
• Add code to the handler that sets the event arg's Handled property to true.
• Add code to the handler that calls the WindowManager's SetFocus() method with a reference to the control you want to get focus.

For example:

private void grdOrders_MouseDoubleClick(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
	e.Handled = true;
	mmAppWPF.WindowManager.SetFocus(this.FocusOnNewElement);
}
