It's hard to see what happens when you don't provide any code sample.

Hi write binding of gridview in one function and call it like

C#

Private void BindNews();
{
 //Binding code
}
protected void grdShowNews_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
  grdShowNews.PageIndex = e.NewPageIndex;
  BindNews();
}

Solution 2

After clicking the Page Number link, your DataSource

C#

news.ListArchive();

will lose its data, so do like this,

In PageIndexChanging Event,

C#

grdShowNews.PageIndex = e.NewPageIndex;

//Method to Load your GridView

Bind_Grid();
