Problem with dockingManager

Hi,

I have a dockingmanger.I t contains a treecontrol.
it is docked to the left side of the window.
On the right side i have a GDBG.
On the load of the page i dont want the treecontrol on the window and i want it when i clicks some button.So i did like this

private void Exp_Load(object sender, EventArgs e)
{
this.dockingManager1.SetDockVisibility(this.loctree, false);
}

But this not working

And also i want one more thing.
I want the GDBG to be docked to the left initially and when i click the button which displays the treecontrol i want the GBDG to be shifted to the right for providing space for the treecontrol to display.
And when i close the dockmanager,i want the GDBG again to be docked to the left side.
Please help me..

Hi Janesh,

You can hide the treeview control during loading of the form by setting the HideonLoad property of docking manager.

[C#]
this.dockingManager1.SetHiddenOnLoad(this.treeViewAdv1, true);

Please refer to the attached sample and let me know if you need more assistance with this incident.
