Make your data access a function like LoadData

E.G

public void LoadData()
{
obj = new Class1();
           Grid_delete_stream.DataSource = obj.getdata("SELECT * FROM stream_tbl");
           Grid_delete_stream.DataBind();

}

Inside your GridView PageIndexChanging event write following

{
LoadData();
gridview1.PageIndex = e.NewPageIndex;
}

See if this helps.
