paging count error asp.net - asp.net

Question

I have a data list with paging which works fine locally debugging but doesn't work on my deployment server provided by my hosting company.
Line 151: TotalRowCount = pagedData.DataSourceCount;
I'm using the same remote database for both local and on deployment server.
Error message:
Server Error in '/' Application.
Object reference not set to an instance of an object.

Answer 1

This implies the connection to your database from the server isn't working, as the pagedData object is null.
Check you can access your datasource, with the correct identity.
