PagedDatasource for gridview paging

Question

I use PagedDataSource for custom gridview paging. Here is the code:

PagedDataSource dataSource = new PagedDataSource(); int virtualRowCount = Convert.ToInt32(dataset.Tables[1].Rows[0]["TotalRows"]); dataSource.AllowCustomPaging = true; dataSource.PageSize = 15; dataSource.VirtualCount = virtualRowCount; dataSource.DataSource = dataset.Tables[0].DefaultView; gvTaxPayerLoginDetail.DataSource = dataSource; gvTaxPayerLoginDetail.DataBind(); 

I return "totals" from my stored procedure (which is set in virtualRowCount) and the actual rows in tables[0] of the data set. I get results, but my pager is gone. The pager is no longer displayed. How can I show gridview to get value from PagedDataSource?

Work with ASP.Net 4

ASP.NET Version 2.0+

This post here http://www.codewrecks.com/blog/index.php/2008/02/09/aspnet-20-gridview-custom-sorting-with-pageddatasource/ extends the standard GridView and provides plumbing code to achieve PagedDataSource integration .

ASP.NET Version 4.5

Set the AllowPaging attribute and AllowCustomPaging attribute in the GridView, as well as the page data source property?

 PagedDataSource dataSource = new PagedDataSource(); int virtualRowCount = Convert.ToInt32(dataset.Tables[1].Rows[0]["TotalRows"]); dataSource.AllowCustomPaging = true; dataSource.PageSize = 15; dataSource.VirtualCount = virtualRowCount; dataSource.DataSource = dataset.Tables[0].DefaultView; gvTaxPayerLoginDetail.AllowPaging = true; // See this line here gvTaxPayerLoginDetail.AllowCustomPaging = true; // and this line here gvTaxPayerLoginDetail.DataSource = dataSource; gvTaxPayerLoginDetail.DataBind();
