That makes sense. Then the control goes into edit mode, it displays a TextBox control over itself to allow editing. It is at this point that it copies it's ContextMenu or ContextMenuStrip to the TextBox. So if you put the control into edit mode before it goes into edit mode, it will never get the new context menu.

Thank you for your reply... I got it.... My issue is related with the AlwaysInEditMode property. Quite a strange behaviour, I don't if it is because still using v7.3 (We will upgrade next month)

If you use the following code you can reproduce my issue.

this.TextBox1.AlwaysInEditMode = true;
this.TextBox1.ContextMenuStrip = new ContextMenuStrip();
this.TextBox1.ContextMenuStrip.Items.Add("Print");

Everything works fine when you write

this.TextBox1.ContextMenuStrip = new ContextMenuStrip();
this.TextBox1.ContextMenuStrip.Items.Add("Print");
this.TextBox1.AlwaysInEditMode = true;

This works fine for me. I'm attaching a sample that uses your code.

Hi Mike

Here is what I'm doing, but that doesn't work. It keeps showing me the default context menu.

What am I missing?

this.tbxMessage.ContextMenuStrip = new ContextMenuStrip();
this.tbxMessage.ContextMenuStrip.Items.Add("Print");
