I would like to check if a particular value already exist in the database Gidview row. If the value already exist, tell the user that he has already entered the record and don't save. otherwise save the record. In my case I want to check the "Random number".
<asp:TextBox ID="txtRandomNumber" runat="server"></asp:TextBox>
Maybe it could be done with a foreach loop statement.

I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.

I'm trying out the jQuery Validation plugin jQuery Docs Here is the markup of my form:
<% using (Html.BeginForm("action", "contoller", null, FormMethod.Post, new { id = "sxform" })){%>
<div id="manifest">
Manifest Option:<br />
<%= Html.DropDownList("docid", ViewData["manifests"] as SelectList, new { @class = "required" })%>
</div>
<div id="release">
Release Version:<br />
<%= Html.TextBox("release", null, new { @class = "required" })%>
</div>
<div id="locale">
Localization:<br />
<%= Html.DropDownList("localization", ViewData["localizations"] as SelectList, new { @class = "required" })%>
</div>
<div id="label">
Label:<br />
<%= Html.TextBox("label", null, new { @class = "required" })%>
</div>
<div id="session">
Session ID (optional):<br />
<%= Html.TextBox("sessionInput", null, new { @class = "required" })%>
</div>
<div id="submit"><input type="submit" value="Build" /></div>
<% } %>
JS:
$(document).ready(function(){
$("#sxform").validate();
});
I am using MS MVC HTML Helpers to render this form. The resulting markup looks fine. IE each input and selection element contains the attribute 'class' with the value 'required'. When I submit this form the validation does noting.
