You're welcome :)

No problem. You are welcome. :) I Love T-SQL "Don't torture yourself,let the life to do it for you."

Well, if you check what events are available, you will see MouseEnter and MouseLeave for when the mouse moves over the control in question. So in the MouseEnter event you would have this.Text = this.fullValue; or something and in MouseLeave i guess you would restore the text. My current favourite word is: Bacon! -SK Genius

yeh...when it display. i connect it to the datagrid, but i couldn't find a way to set the width of the column in there.

I'm not 100% sure what you mean... can you be a bit more descriptive/specific? Are you saying you want one MdiParent with child forms that can access each other? (Close each other etc)? Matthew Butler

Well, I just want an expander function like how WPF have it, but not sure how to create that in WinForm?
