How do I set the Size of a DockPanel in a docked state at runtime?  Here's my simple code.

panel = new Telerik.WinControls.Docking.DockPanel();

panel.DockState = Telerik.WinControls.Docking.

DockState.Docked;
panel.Size = new Size(250, 250);

For some reason the Size is not set.  It just remains the same.

Thanks,
Ryan

Hello Ryan,

Please attach the created DockPanel to the DockingManager before you set its Size property:

 panel = new Telerik.WinControls.Docking.DockPanel(); 
 dockingManager1.SetDock(panel, DockPosition.Left); 
 panel.Size = new Size(250, 250);

Thanks for the quick reply. 

The DockPanel is already attached to a DockingManager and I already call SetDock.  The Size still does not get set.

I have a form with a dockManager that contains 3 dockPanels.  dockPanel1 is docked on the left.  dockPanel2 is docked on the right.  dockPanel3 is docked on the bottom.  When the code below runs the width of dockPanel3 does not change to half its current width as expected.  Is there a way to set the size?

//This code is in the windows Form
protected

override void OnLoad(EventArgs e)

{

    base.OnLoad(e);

    dockPanel3.DockState = Telerik.WinControls.Docking.

DockState.Docked;

    dockPanel3.DockManager.SetDock    
(dockPanel3,     Telerik.WinControls.Docking.

DockPosition.Bottom);

    dockPanel3.Size =

new Size(dockPanel3.Width / 2, dockPanel3.Height);

}

Ryan,
     If you set dockPanel3 to dock on the bottom it will fill the entire bottom of the DockingManager, so you cannot set the size.  I am assuming you are wanting to have a three panel layout where dockPanel1 and dockPanel3 share the same vertical area while dockPanel2 fills the remaining area, or some variation of this layout.  If that is correct, I have provided an XML layout below.  An easy way to build your layout is to use the Advanced Layout Designer which is accessible from the DockingManager SmartTag menu.  You can call the SaveXML and LoadXML methods once you have the layout how you like it.  I hope this helps. 

dockingManager1.LayoutTree = "<?xml version=\"1.0\" encoding=\"utf-8\"?><DockingTree xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><Sites Type=\"Telerik.WinControls.Docking.AutoHideContent\" Assembly=\"Telerik.WinControls.Docking, Version=7.1.1.0, Culture=neutral, PublicKeyToken=5bb2a467cbec794e\"><Sites Orientation=\"Horizontal\" Size=\"501;395\" HidePosition=\"0\"><Dockables /><Rigth Orientation=\"Horizontal\" Size=\"501;395\" HidePosition=\"0\"><Dockables /><Left Orientation=\"Vertical\" Size=\"236;395\" HidePosition=\"0\"><Dockables /><Left Orientation=\"Horizontal\" Size=\"236;192\" HidePosition=\"Left\"><Dockables><XmlDockable Text=\"dockPanel1\" DockState=\"Docked\" DockPosition=\"Left\" PreferredDockSize=\"100;200\" PreferredFloatSize=\"150;300\" Guid=\"07d9e734-e472-4926-950d-f32f00d3cb6f\" Type=\"Telerik.WinControls.Docking.DockPanel\" Assembly=\"Telerik.WinControls.Docking, Version=7.1.1.0, Culture=neutral, PublicKeyToken=5bb2a467cbec794e\" CaptionVisible=\"True\" TabStripVisible=\"True\" CloseButtonVisible=\"True\" HideButtonVisible=\"True\" DropDownButtonVisible=\"True\" /></Dockables></Left><Rigth Orientation=\"Horizontal\" Size=\"236;199\" HidePosition=\"Left\"><Dockables><XmlDockable Text=\"dockPanel3\" DockState=\"Docked\" DockPosition=\"Bottom\" PreferredDockSize=\"100;200\" PreferredFloatSize=\"150;300\" Guid=\"73a56b8e-759b-435c-b206-f0e02d58366d\" Type=\"Telerik.WinControls.Docking.DockPanel\" Assembly=\"Telerik.WinControls.Docking, Version=7.1.1.0, Culture=neutral, PublicKeyToken=5bb2a467cbec794e\" CaptionVisible=\"True\" TabStripVisible=\"True\" CloseButtonVisible=\"True\" HideButtonVisible=\"True\" DropDownButtonVisible=\"True\" /></Dockables></Rigth></Left><Rigth Orientation=\"Horizontal\" Size=\"261;395\" HidePosition=\"Right\"><Dockables><XmlDockable Text=\"dockPanel2\" DockState=\"Docked\" DockPosition=\"Right\" PreferredDockSize=\"100;200\" PreferredFloatSize=\"150;300\" Guid=\"a1696d86-ad3a-42b1-bdff-4416c33bfb20\" Type=\"Telerik.WinControls.Docking.DockPanel\" Assembly=\"Telerik.WinControls.Docking, Version=7.1.1.0, Culture=neutral, PublicKeyToken=5bb2a467cbec794e\" CaptionVisible=\"True\" TabStripVisible=\"True\" CloseButtonVisible=\"True\" HideButtonVisible=\"True\" DropDownButtonVisible=\"True\" /></Dockables></Rigth></Rigth></Sites></Sites></DockingTree>";

Hi Ryan,

The solution provided by John is absolutely correct. Thank you, John!

When you dock DockPanel to the Top or Bottom zone, you can change the Height, but not the Width. For Left- and Right-docked DockPanels you can change the Width only.

Feel free to contact us if you have additional questions.
