How to use? that is not an acceptable title. Hidden has 2 'd's not 3. Hi has one 'i' and I take it Frds is meant to be Friends?

Hey there,

If you don't assign a value to the hidden control then it won't return a value on postback. Simple as that :)

ASP.NET

<input id="Item_ID" type="hidden" name="Item_ID" runat="server" value="2" />

Please, See the value attribute I've set.

What DaveAuld is trying to tell you is that, this is a professional forum, not a SMS service. So use correct spellings to the best of your strength.

@DaveAuld: Perhaps, he might not be fluent in using his english. Just in case, cut him some slack :)

Hope this helps, regards

Hi,

You can bind value to hidden field directly like,
value = '<%= YourServerSideVariable%>'

Here note that "YourServerSideVariable" must be public.

Thanks
