DevExpress : Cannot unregister UpdatePanel with ID ‘UpdatePanel1’

I was using the DevExpress tab control and was suddenly came across the error : “Cannot unregister UpdatePanel with ID ‘UpdatePanel1’ since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported. Parameter name: updatePanel”

the solution to the above error instead of the line

tabControl.TabPages['abc"].Visible = false;

//Or setting

tabControl.TabPages['abc"].Enabled = false;

change to

tabControl.TabPages['abc"].ClientVisible = false;

//Or setting

tabControl.TabPages['abc"].ClientEnabled = false;

refer this link for more details.
