Can I show custom Confirm dialog before some operation
<p>I am using <code>ASP.NET/C#</code>.In one of my page I have a requirement where before <code>inserting data</code> into <code>database</code> I need to check if the <code>ApplicationNo</code> is unqiue.If it is not unique I need to show a <code>confirm dialog</code> which will inform the user that the <code>ApplicationNo</code> is not unique.Can I use custom <code>confirm dialog</code> for this purpose.
Thanks.</p>
