SuspendLayout / ResumeLayout WinForms Designer Support

[Roy Muller]

I was wondering if anyone knows the trick to having the Windows Forms Designer know that a control supports SuspendLayout/ResumeLayout in its InitializeComponents() method. Is there some attribute to use, or an interface to implement?

I apologize for this being slightly off-topic, but I can''t find this information anywhere.

Thanks,

I''ll try this question in the Windows Forms Forum.

Hi Roy, Looking at the code (in Reflector) for the ControlCodeDomSerializer class, it appears that these calls get added in only when the control being serialized has child controls. If you wish to add them in for any other reason, you can derive from CodeDomSerializer to implement a CustomCodeDomSerialzer. This MSDN article has a sample and related information: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/custcodegen.asp

// code from ControlCodeDomSerializer 
  if (this.HasSitedNonReadonlyChildren((Control) value))
            {
                  this.SerializeSuspendResume(manager, (CodeStatementCollection) obj1, value, "SuspendLayout");
                  this.SerializeSuspendResume(manager, (CodeStatementCollection) obj1, value, "ResumeLayout");
            }

Best regards, Daniel
