Answer : Disable the right mouse button for pasting into a textbox

Instead of ContextMenuStrip use ContextMenu,

so, code in form load event should look like,
TextBox1.ContextMenu = New ContextMenu()

In case of any issue, you can find context menu control listed on the toolbar with other controls like label, buttons, etc.
