Hi Chiranthan,
Thanks for using Syncfusion products.
We have created a simple sample to illustrate To show/Hide the AutoHidden window in DockingManager which you can download below.
In this sample, we have used the “SelectTab” method to Show the Auto-hidden window and “AutoHideTab” method to Hide an Auto-hidden window.
Please let us know if the sample helps.
Regards,
Surya Narayana
