How to validate textarea?

[brett]

If I try to use a RequiredFieldValidator control to make sure a
textarea isn't empty, I get an error similar to

Unable to find control id 'comment' referenced by the
'ControlToValidate' property of 'rvfComment'.

I'm guessing this control does not validate a textarea. What else can
I do for this besides checking its length on postback?

Thanks,
Brett

By textarea do you mean the non-.NET <textarea> or the appropriate
<asp:TextBox TextMode="MultiLine">?

You need to be using the latter...

You are right. I was using the wrong element.

This is what I had:
<TEXTAREA id="txtcomment" name="comment" rows="5" wrap="soft" cols="50"
runat="server"></TEXTAREA>

You can see it is runat="server". I grabbed it off the VS.NET toolbar.
If this is a regular HTML textarea, how can it runat server?

Thanks,

For some reason, the validation works on my local machine but not on
the server. It will validate everything but once all of the fields are
valid and I click submit, nothing happens. The submit seems to be
disabled on the server after valid data has been entered. What may be
happening?

Thanks,

Hi Brett,

Check .NET Framework version in your server. It might be different from the
version in your developing machine. And installing framework sp1 may solve
the problem.

I see in my FTP folder the same version of 1.1 is there. 2.0 is also
there.

What I mean is that in both server and your local machine you have
Framework Version:1.1.4322. But they might be little bit different. For
example, in server it’s Framework Version:1.1.4322.573. But in local machine
it’s Framework Version:1.1.4322.2XXX.

If that really is the problem, what is the resolve for that? I don't
have access to the ASP.NET admin on the share.

Thanks,

In our case, we installed .NET Framework 1.1 SP1 on server. The version info
is like:

Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET
Version:1.1.4322.2032

That solved the problem.
