Select text in asp:textbox

TJHerman · Sep 5, 2006

I am using Visual Studio 2005 and writing all code-behind in VB. I'm setting
the focus of a textbox after I run some calculations. I want to additionally
select all the text in the textbox that I've set the focus to so that the
user doesn't have to manually select the text and type. Can someone give me
an example of how to do this programmatically using vb?

Hi TJ,

Here's a little code that inserts some JavaScript when the page loads to
select the text in a textbox.

If you can use Atlas, you'll find a really nice technique for creating a
Textbox watermark:

Let us know if this helps?
