Hi,

I am doing POC on RADGrid with Slider paging.
But I am getting an exception as "Input string was not in a correct format." when I move / drags slider for paging. It's not working for me. I am attaching my ASPX and VB.Net code along I will appreciate if I can get feedback as early as possible.

We are planning to incorporate Telerik controls in our application for rich feel and high performance but only if I get rid of these kind of minor error which eats lots of head.

Hello Avinash,

I tested the setup in question, and the control behaved as expected.
Attached to this message, is the code, which I used for testing. Take a look at it and let me know if this is the expected behavior.
