Setting focus of a control

[Guest]

Hi,

I have a textbox in which in the TextChanged event I check to make sure they
entered in valid data, however if the data isn't entered properly I want the
cursor to go back to that text so they can fix the error.

Any ideas on how to do this?

Regards
Brian

Brian,

Add a hidden input and set it on the server side to the client id of the
control you want to set focus on. On client side, check the input in the
body's onload event and set the focus with

document.getElementById(hiddenInput.value).focus();
