Hi Limor,
I was able to reproduce the issue. It has fixed internally in the final release of Essential Studio V3.3. If you are interested in upgrading a latest release, please let me know.
I have created a workaround for this issue. Please use the following statement in your sample.
private void DelControls()
{
foreach (Control c in m_buttons)
{
//Gets the current AutoHide state of the control.
if(dockingManager1.GetAutoHideMode(c)==true)
dockingManager1.SetAutoHideMode(c,false);
//Disabled docking for the control
dockingManager1.SetEnableDocking(c, false);
}
}
Please refer the attached sample and let me know if this is helps you. Thanks for using Syncfusion Products.
Regards,
Vijay
