Answer 1

In your web.config file, add a parameter like GridViewPageSize. Then in your code write the following:

gvTable.PageSize= int.Parse(ConfigurationManager.AppSettings["GridViewPageSize"]);

You need to import the namespace System.Configuration for ConfigurationManager class.

Answer 2

There are two solutions for this issue

first of them is to build your pager control and override render method . the other solution is to implementing IPageableItemContainer in gridview then use DataPager control. Check the following link for last solution:
