You can force your Pager to remain visible !
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridView1.BottomPagerRow.visible = True
BTW you have already defined pageSize and set Paging to true so i think this will do
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}
private void BindGrid()
{
GridViewDBEntities model = new GridViewDBEntities();
var query = from p in model.userTbls select p;
GridView1.DataSource = query;
GridView1.DataBind();
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
// GridViewDBEntities model = new GridViewDBEntities();
// var query = (from p in model.userTbls orderby p.id ascending select //p).Skip((e.NewPageIndex) * GridView1.PageSize).Take(GridView1.PageSize);
GridView1.PageIndex = e.NewPageIndex;
// GridView1.DataSource = query;
//GridView1.DataBind();
BindGrid();
}
Removing !IsPostback will cause problems later if you have to implement some functionality where you have to edit grid or insert records , Either way better will be to create a Bind method and use it according to requirements .
