  Hi Rambabu,

  Thank you for providing the screenshot. We could observe the behavior you mentioned when the DockTabControl.SelectedIndex property is set through XAML or code. We have reported it to the development team for further investigation and will let you know the updates soon.

  If this the case on your end as well, then as a workaround, you can handle the DockTabControl.Loaded event and set the SelectedIndex in the event handler instead. Please see the attached sample project for reference.

  If you still face this issue with a different implementation, please update the attached project to reproduce the issue, so we can investigate further and assist you in the best way possible.

  Hello,
  
  I created a sample to replicate the issue.
  
  this issue happens very randomly and unable to find a specific pattern.

  here is the video that illustrates the issue.https://www.awesomescreenshot.com/video/30004374?key=b5423f52e085782d5adb17bddd61aa69 DockControlTabs.zip

  Hi Rambabu,

  We previously reported a similar issue related to the measurement of TabItems to the development team. They have internally fixed the issue, and the ETA for the fix is the upcoming 2024v1 Hotfix2 release. We will let you know as soon as the release is available for download.

  Unfortunately, we were unable to reproduce the issue you just described, as it appears to be uncertain. We noticed that you are using an older version of the DockTabControl. Could you please test with the latest version (8.0.20241.854) and see if the issue persists? If so, please share another video showing the version used and the issue occurring, so we can confirm it with the development team.

  Thanks, and Kind Regards,

  Hi Rambabu,

  The development team researched your sample project and were able to reproduce the issue. They suggested a workaround that fixed the issue on their end by adding the following code at the end of the Add_Tab method:

  private void Add_Tab(object sender, RoutedEventArgs e)
  {
   	//........
    	if (docTabControl.Items.Count > 1)
          {
          	docTabControl.ScrollIntoView(docTabControl.Items[0]);
                  docTabControl.ScrollIntoView(dockTabItem);
           }
  }

  Please refer to the updated sample project for reference - DockControlTabs_Workaround.zip

  Best Regards,
