Pageindexchanged nicht funktioniert

Question

Ich bin mit RadGrid mit Pager. Wenn auf einen Pager auf der nächsten Seite Nummer klicken die Daten nicht (unverbindlich die Daten) angezeigt wird. Kann jemand mir helfen, dieses Problem zu beheben. hier ist mein Code.

protected void Page_Load(object sender, EventArgs e)
{
    try
    {
        if (!IsPostBack)
        {
            Session["SearchRes"] = null;
            if (Session["TaskName"] != null)
                lblTskName.Text = Session["TaskName"].ToString();
            Session["FilColms"] = null;
            Session["SortExp"] = null;
            Session["FilExp"] = null;
            Session["ViewAll"] = null;
            BindGrid();
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

private void BindGrid()
{
    try
    {
        DataSet dsResult = new DataSet();

        clsSearch_BL clsObj = new clsSearch_BL();
        clsObj.TaskID = (string)Session["TaskID"];
        clsObj.CustName = (string)Session["CustName"];
        clsObj.MarketName = (string)Session["MarketName"];
        clsObj.HeadendName = (string)Session["HeadendName"];
        clsObj.SiteName = (string)Session["SiteName"];
        clsObj.TaskStatus = (string)Session["TaskStatus"];
        clsObj.OrdType = (string)Session["OrdType"];
        clsObj.OrdStatus = (string)Session["OrdStatus"];
        clsObj.ProName = (string)Session["ProName"];
        clsObj.LOC = (string)Session["LOC"];
        clsObj.QuoteID = (string)Session["QuoteID"];
        clsObj.CMNumber = (string)Session["CMNumber"];

        if (Session["SearchRes"] == null)
        {
            dsResult = clsObj.getSearchResults_BL(clsObj);
            Session["SearchRes"] = dsResult;
        }
        else
            dsResult = (DataSet)Session["SearchRes"];

        DataView dataView = dsResult.Tables[0].DefaultView;
        rg200.DataSource = dsResult;
        rg200.DataBind();
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

{

    if (Session["TaskID"] != null)
    {
        string strTaskID = (string)Session["TaskID"];
        if (strTaskID != string.Empty)
        {
            clsTaskUpdates_BL objBL = new clsTaskUpdates_BL();

            GridEditableItem editedItem = e.Item as GridEditableItem;
            //Get the primary key value using the DataKeyValue.      
            string OrdID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["orderId"].ToString();
            //Access the textbox from the edit form template and store the values in string variables.

            string ClarifyAccountNbr = ((GridTextBoxColumnEditor)editedItem.EditManager.GetColumnEditor("Clarify Account Nbr")).TextBoxControl.Text;

            string SiteID = ((GridTextBoxColumnEditor)editedItem.EditManager.GetColumnEditor("Site ID")).TextBoxControl.Text;
