Hi I want pagging datalist with use Entity Framework but the result is just view one page :
This is my code :

testEntities context=new testEntities();
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindDataList(10, 0);
    }
    else
    {
        PlaceHolder1.Controls.Clear();
        CreatePagingControl();
    }
}

private int RowCount
{
    get
    {
        return (int)ViewState["RowCount"];
    }
    set
    {
        ViewState["RowCount"] = value;
    }
}
private void BindDataList(int take, int pageSize)
{


    var query = (from p in context.testTBL orderby p.testID select p).Take(take).Skip(pageSize).ToList();
    PagedDataSource page = new PagedDataSource();
    page.AllowCustomPaging = true;
    page.AllowPaging = true;
    page.DataSource = query;
    page.PageSize = 3;
    DataList1.DataSource = page;
    DataList1.DataBind();

    if (!IsPostBack)
    {
        RowCount = query.Count;
        CreatePagingControl();
    }
}

private void CreatePagingControl()
{
    for (int i = 0; i < (RowCount / 10) + 1; i++)
    {
        LinkButton lnk = new LinkButton();
        lnk.Click += new EventHandler(lbl_Click);
        lnk.ID = "lnkPage" + (i + 1).ToString();
        lnk.Text = (i + 1).ToString();
        PlaceHolder1.Controls.Add(lnk);
        Label spacer = new Label();
        spacer.Text = " ";
        PlaceHolder1.Controls.Add(spacer);
    }
}
void lbl_Click(object sender, EventArgs e)
{
    LinkButton lnk = sender as LinkButton;
    int currentPage = int.Parse(lnk.Text);
    int take = currentPage * 10;
    int skip = currentPage == 1 ? 0 : take - 10;
    BindDataList(take, skip);
}

this is HTML code :

<div>
    <asp:DataList ID="DataList1" runat="server">
        <ItemTemplate>
            <%# Eval("testID")%>
        </ItemTemplate>
    </asp:DataList>
    <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</div>

And this is Output :
