  I am looking to find the last focused tab when having multiple docked windows, as shown in the screenshot below.

  For instance, suppose I have 5 tabs within DockedWindow1 and 3 tabs within DockedWindow2. If my most recent interaction was with Tab 7 in DockedWindow2, I’d like to be able to identify the current active DockedWindow.

  Hi Rambabu,

  You can create a variable to store the C1DockTabControl instance that fires the most recent SelectionChanged event. We have created a sample application that shows the implementation.

  Please check LastFocusedTab.zip for full implementation.

  Thanks & Regards,

  Hello Aastha,
  
  Thank you for the solution, but this doesn’t work as expected when you have only 1 tab in the Dockedwindow2.

  please refer to the video.

  Hi Rambabu,

  As per our understanding, you want to fetch the C1DockTabControl associated with the last clicked C1DockTabItem. It should not be dependent on whether the selection is changed or not.

  In order to achieve the desired requirement, you can handle C1DockTabControl’s GotFocus event. Please refer to the following code snippet for the same:

  private void DockWindow_GotFocus(object sender, RoutedEventArgs e)
  {
      var ele = sender as C1DockTabControl;
      if (ele != null)
      {
          var focussedEle = ele.InputHitTest(Mouse.GetPosition(ele));
          if (focussedEle.GetType() == typeof(Border) && ((Border)focussedEle).TemplatedParent.GetType() == typeof(C1TabItemBorder))
          {
              _activeWin = ele;
          }
          else if (focussedEle.GetType() == typeof(TextBlock) && ((TextBlock)focussedEle).TemplatedParent.GetType() == typeof(ContentPresenter))
          {
              var parentEle = ((TextBlock)focussedEle).TemplatedParent as ContentPresenter;
              if (parentEle.TemplatedParent.GetType() == typeof(C1DockTabItem))
              {
                  _activeWin = ele;
              }
          }
      }
  }

  Kindly refer to the attached sample for full implementation. (See LastFocusedTab_Mod.zip)

  Thanks & Regards,
