Is that possible to set a multi-line textbox a background image?

I have a textbox co开发者_Go百科ntrol (multi-line enabled). Is that possible to assign it a background image?

I'm assuming this is a WinForms application?

There is no 'built-in' way of doing this. You can override the controls paint method (onPaintBackground - I believe) and draw the image yourself.

If it's Web based or WPF - you're in luck.

It's possible. Just add the image location to the text box styling:

<asp:TextBox id="TextBox1" runat="server" style="background-image: url( images/myTextboxImage.jpg ); border: none;" />

EDIT: As Rob pointed out in his answer: this is only if you're doing it on the web.
