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 :)
<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
