Here's a real newbie question --
How can you set the focus to a web control textbox in asp.net server-side code? Depending upon what the user enters in a textbox, I'd like to set the focus to one of two other textboxes.

Client-side javascript works onload to set the focus but I want to set it at runtime and there is no textbox.focus().

Thanks for any help!

Hi Hilda,

There is indeed no TextBox.focus() as it wouldn't make much sense on the server (although I can imagine that a Server-side .focus() method would be able to send JavaScript to the browser. Maybe that's something for ASP.NET 2)

You'll need to emit some JavaScript to the client yourself that sets the focus from a function at the end of the file, or through the onload handler of the page.

Take a look at the RegisterClientScriptBlock and the RegisterStartupScript methods in the MSDN help. These methods allow you to send JavaScript to the browser.

Cheers,

Imar

Yes, I see. Thanks! It's really just a matter of setting the client-side event handler on a web control.

You can also set the handler by writing the client-side script in the html and then in the code behind in the Page_Load write:
webcontrolname.Attributes.Add("eventname","client-side_function();")
