Disable editing child controls of custom DevComponents.DotNetBar control

Question

I have created a new Custom Control inheriting from Bar control of DevComponents.DotNetBar controls. Next, I have created a new dock tab in it and have added my other controls to it.

After I compile my Custom Control and add my created Custom Control in a new Windows Form, Dock Tab Controls are editable at design time.

I don't want that anybody can edit these controls (Dock Tab Controls) in design time. How can I disable editing the controls at design time from the form (not the same as editing the control itself)?

Answer 1

You must extend the design mode behavior by using ParentControlDesigner Class. ParentControlDesigner Class provides a base class for designers of controls that can contain child controls.

So, for achieve to your Goal, you must implement design-time services for a component by DesignerAttribute as the following (Just add below code before the written class):

[Designer("System.Windows.Forms.Design.ParentControlDesigner, System.Design", typeof(IDesigner))]
public partial class barFloorsGrouping : Bar
{
...
}

Answer 2

EDIT: As always I work in asp.net and webforms... This answer is for WebForms

You would need to override the GetDesignTimeHtml of the WebControl.

see MSDN docs

It sounds to me like you haven't done a lot of server control creation so you are in for a lot of fun...
