    Hi,

    I have added DockTabControl inside C1DockGroup control. When I tried to drag and dock any DockTabControl to right/left of C1DockControl, a blank space is created as mentioned in attached image (Please refer attached image). When clicking that blank space, immediately “Visual is not connected to PresentationSource error is thrown” and application got crashed. Please refer attached solution file.

    Any suggestion please?.

    Thanks and Regards,

    Vinoth Kumar Ravi

    Hello,

    I’m afraid that it is difficult to diagnose this problem based only on the information available. I have attached here a sample project where the C1DockControl has a C1DockGroup with multiple C1DockTabControl placed inside. With this layout, I do not get an exception irrespective of the docking I try.

    So, can you please ensure that you are using the latest packages and if still you face the problem, can you please modify the attached application to demonstrate the problem?

    Regards,

    C1DockControl_WPF.zip

    Hi Ruchir,

    Please find below scenarios to reproduce the issue.

    1. Run Application with MainWindowModified.xaml as startup window
    2. Click Add Button to add controls to C1DockGroup control.
    3. Once added, try to drag and dock any DockTabControl.
    4. Once docked, a blank space will get created in DockGroupControl.

    Thanks and Regards,

    Hello,

    This is just to update you that with your application I can see the blank space and the problem seems specific to your implementation/customizations, so I am investigating on this and will let you know an update soon.

    Hi Ravi,

    Following is the response received from the development team:

    I commented those lines and exception is gone, but the drop position still not correct.

    So, we recommend you to use the attached sample (C1DockTabControl_BindingListObject.zip), which binding List object to C1DockControl: https://www.dropbox.com/s/9avq1s5wypxk7si/C1DockTabControl_BindingListObject.zip?dl=0

    Hello,

    Following is the information received from the team:

    On the sample shared earlier, we have list data model (AllAccounts). From that list, we do the same as you: Create DockTabControl, create DockTabItem with data model. And Dock control takes care the rest.

    On your sample, you tried to Create DockTabControl, create DockTabItem on your way and it causes error.

    We conclude that this issue comes from your sample, not our control, So we attached working sample as reference. Also, we pointed out the error part on attached image on the previous comment.

    Hope this helps.

    Regards,

    Hi Ruchir,

    I want to know one thing. Is the issue occurs because of applying our custom template to your DockTabControl?

    Thanks and Regards,

    Hello,

    In your sample, you tried to create DockTabControl, create DockTabItem in your way and it causes error whereas in the sample shared on Nov7, developers have a list data model (AllAccounts) and from that list, they created DockTabControl, created DockTabItem with data model and dock control takes care the rest.

    That is why I conclude that this issue comes from your sample not from the control.

    I also pointed out the error part on attached image.

    Thanks,

    Hi Ruchir,

    I can understand where that issue occurs. Can you please clarify on the below?

    Shall we change the template of C1DockTabControl?

    By changing the template Is it will affect any default functionality?

    Thanks and Regards,

    Yes, changing the control template can affect interaction behavior of the control.
