PageIndexChanged ne fonctionne pas

Question

J'utilise RadGrid avec téléavertisseur. En cliquant sur le numéro de page sur un téléavertisseur les données n'affiche (pas lier les données). aide Quelqu'un peut-il me résoudre ce problème. voici mon 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"];

        rg200.DataSource = dsResult;
        rg200.DataBind();
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

protected void rg200_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{

    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;

Votre code montre que vous utilisez de liaison avec les appels DataBind (). De cette façon, vous devez modifier manuellement l'index de page crochetage source de données PageIndexChanged, assign au réseau et le lier. Vous pouvez également utiliser NeedDataSource liant à certains de rechange codage manuel.
