SetEnableDocking exception

Question

Hi,

I have a form with DockingManager. I add controls to the DockingManager and at some point i want to remove the controls. I get an exception when one of the controls is hidden (AutoHide):

public class Form1 : Form
{
private DockingManager dockingManager1;
...
private ArrayList m_buttons = new ArrayList();

private void AddDockingControl()
{
Button b = new Button();
m_buttons.Add(b);
dockingManager1.SetEnableDocking(b, true);
}

private void DelControls()
{
foreach (Control c in m_buttons)
{
dockingManager1.SetEnableDocking(c, false);
}

I''m using version 3.0.1.0

Thanks,

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
