How to add context menu dynamically to the RichTextBox on right click.

In this article I am going to discuss How to add context menu dynamically to the RichTextBox?  Please check below to implement it.

1- Add mouse up event in RichText Box

<RichTextBox Name="RichTextBoxCommand" MouseUp="RichTextBoxCommand_MouseUp"></RichTextBox>

2- Dynamically add context menu on MouseUp event.

 if (e.RightButton == Mouse.RightButton)
            {
                ContextMenu contextMenu = new ContextMenu();
                MenuItem selectAllmenu = new MenuItem();
                selectAllmenu.Header = "Select All";

                selectAllmenu.Click += (o, a) =>
                 {
                     RichTextBoxCommand.SelectAll();
                 };

                MenuItem copymenu = new MenuItem();
                copymenu.Header = "Copy";
               
                copymenu.Click += (o, a) =>
                {
                    RichTextBoxCommand.Copy();
                };


                contextMenu.Items.Add(selectAllmenu);
                contextMenu.Items.Add(copymenu);
                RichTextBoxCommand.ContextMenu = contextMenu;
            }

Here I added two sub menu Select All and Copy. As you right click on Rich text box. both menus will display there.
