    How do I disable context menus "EditHeader" and "EditFooter", so that they don't show up?

    How do I remove (rather than disable) context menu item "Hyperlink..."?

    Hello, Mihajlo, 

    The following code snippet demonstrates how you can control which items to be visible in the context menu that RadRichTextEditor shows and hide the redundant ones:

    public RadForm1()
    {
        InitializeComponent();
     
        Telerik.WinControls.RichTextEditor.UI.ContextMenu menu =
            this.radRichTextEditor1.RichTextBoxElement.ContextMenu as Telerik.WinControls.RichTextEditor.UI.ContextMenu;
        menu.ContentBuilder = new CustomContextMenuContentBuilder();
          
    }
     
    public class CustomContextMenuContentBuilder : Telerik.WinForms.RichTextEditor.RichTextBoxUI.Menus.ContextMenuContentBuilder
    {
        public override Telerik.WinForms.RichTextEditor.RichTextBoxUI.Menus.ContextMenuGroupCollection Construct()
        {
            Telerik.WinForms.RichTextEditor.RichTextBoxUI.Menus.ContextMenuGroupCollection collection = base.Construct();
     
            foreach (var item in collection)
            {
                Telerik.WinForms.RichTextEditor.RichTextBoxUI.Menus.ContextMenuGroup group = item as Telerik.WinForms.RichTextEditor.RichTextBoxUI.Menus.ContextMenuGroup;
                if (group!=null)
                {
                    foreach (var menuItem in group)
                    {
                        if (menuItem.Text.Contains("Hyperlink") )
                        {
                            menuItem.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
                        }
                    }
                }
            }
            return collection;
        }
     
        private void menuItem_Click(object sender, EventArgs e)
        {
            Console.WriteLine("Clicked");
        }
    }

    I hope this information helps. If you need any further assistance please don't hesitate to contact me.
