I have connected a div tag in javascript to show validation error messages.If there is an error the error msg will appear. If the user clicks the button the user should not be allowed to move to next page so i am checking the visibility of div in codebehind. How to do that.

add runat="server" in your div tag.

As Raje has pointed out, you can access a DIV tag from your code behind by adding the runat="server attribute to the DIV tag on your page:

ASP.NET

<div id="myDivTag"  runat="server" class="someCSS">
     my div
</div>

Then you can access the tag from your code behind to test it's visibility like so:

C#

if (myDivTag.Style["Display"] != "none")
{
     // DIV is visible, so do some stuff
}
