Q: Modify a TextBox control

[Visual Systems AB \(Martin Arvidsson\)]

Hi!

Can any one point me in direction of modify a TextBox control.

What i want to do is to add a button, like the ComboBox have. with my own
bitmap
and execute an Event when clicked.

I will use this to bring a lookup table when searching for customers.

Regards
Martin Arvidsson

Hi Martin,

just fake it. Create a custum usercontrol.
Place a normal textbox control on it. Then
add a transparent label to the left corner
of the textbox. Add an imagelist to your
control create a gif set this imagelist
as imagelist for your label. At least add
a new textbox and place it over the rest
of the visible underlaying textbox. Set
the second textbox to borderstyle none.
Et voila.

Here is a quick made one. Notice, that you
will have to add your graphics.

Cheers
