GridView Records are inserted / not
<p>I have a 3 GridvViews : <strong>To</strong>, <strong>Cc</strong>, and <strong>Bcc</strong>. After entering the values to Grids, I want to save those Records.</p>

<p>My question is: at the time of saving, how do I check if there is there in 3 Grids or not?
e.g. If I insert records for <strong>To</strong>, but not for <strong>Cc,Bcc</strong> , then I would like it to show an error message:</p>

<pre><code>"error enter at least one record..."
</code></pre>

<p>I tried the following script hooked into the <strong>Save</strong> button by using the <strong>OnClientClick</strong> callback. But it isn't working.</p>
