How to lock the docked windows on a form to prevent the layout of the form from being altered accidentally?

Platform: WinForms |
Control: DockingManager |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014

 

You can handle the DockingManager’s DragAllow event for this purpose and set the DragAllowEventArgs’ Cancel property to True as shown below:

This will prevent the docking windows from being dragged and the GUI layout being changed accidentally.

C#

private void dockingManager1_DragAllow(object sender,

Syncfusion.Windows.Forms.Tools.DragAllowEventArgs arg) {

arg.Cancel = true;

}

VB

Private Sub dockingManager1_DragAllow(ByVal sender As Object, ByVal arg As

Syncfusion.Windows.Forms.Tools.DragAllowEventArgs) Handles dockingManager1.DragAllow

arg.Cancel=True

End Sub
