ello I've got some problem wih the paging of Telerik RadGrid Control! When it's first page - there is no problem it loads me three rows as I have givenpageSize property value - "3". But when I try to get to the second page - it gives me an error:
Here is my aspx file
<
And here is my cs File with only one function in which I get the data for datasource from a web service and bind it to the radGrid:
39e - JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 404Here is my aspx file

Hi ,
It seems strange that an error 404 is thrown when paging. This error is generally shown when a requested page was not found.
Would you check the PageIndexChanged handler and ensure that the code there is not the cause for the error? If the issue is not there, would you share your full markup with the code-behind so we could have better understanding of your scenario?
On a side note, the NeedDataSource event is generally used for setting the DataSource for RadGrid. It is fired every time the grid needs to be bound to a data source. You do not need to set the CurrentPageIndex or the VirtualItemsCount properties in this handler. If you would like to use custom paging you would find this online demo interesting.
