Validate between 2 textboxes

[light of mind. heavy of belly]

Hi,

I need to validate that at one of 2 textboxes has some data in it. Is it
possible to hook the validation system to do this bearing in mind that empty
textboxes are not evaluated?

Thanks for your ideas.

I'm not sure of any way you can use the validator controls in this
scenarios. It would be much easier to write a small Javascript that
check the values of those controls.

a single IF statement would actually do the trick.

Hmm, I really wanted to hook this stuff to the validation bits for
consistency's sake.

OK, so how would I go about doing that exactly?

Heres my first attempt at calling some client script:

protected void Page_Load(object sender, EventArgs e)

{

string script = @"

<script language=JavaScript>

function doEmailOrPhoneCheck(){

alert('here');

return false;

}

</script>";

RegisterClientScriptBlock("onSubmitCheck", script);

SubmitButton.Attributes.Add("onsubmit", "onSubmitCheck");

}

What am I doing wrong?

Thanks

A CustomValidator would give you what you need on both the server and
client sides. Check out this example:
