Grid Value Not showing

[Joby]

Hi, I have one telerik rad grid.Using a method i am filling the grid.I have enabled paging property.I have used itemtemplate-->ImageButton for delete and edit options.I have set page size as 10.Page load time it is working properly and populating the grid.After inserting 11 th row the pagination starts and it will show in next page with one record.But when i am deleting the 11th row the grid become blank.I have used dataset to bind the records. radgrid.DataBind(); dsDataset.Dispose();. But its item.count is 0. What is the reason?

protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            if (!IsPostBack)
            {
                PopulatePackage();
            }
        }
        catch (Exception ex)
        {
            lblMessage.Text = objUtl.GetErrorMessage(ex, this);
            lblMessage.Visible = true;


protected void gvPackage_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    {
        try
        {
            SqlHelper objSQL = new SqlHelper();
            DataSet dsPackage = new DataSet();
            dsPackage = objSQL.ExecuteDataset("AL_PackageType_List_Retrieve",
                                             objUtl.NumericEntry(Session["LocationId"].ToString()));
            gvPackage.DataSource = dsPackage.Tables[0];
            dsPackage.Dispose();
            //PopulatePackage();
        }
        catch (Exception ex)
        {
            lblMessage.Text = objUtl.GetErrorMessage(ex, this);
            lblMessage.Visible = true;
        }
    }





private void PopulatePackage()
    {
        try
        {
            lblMessage.Text = string.Empty;
            SqlHelper objSQL = new SqlHelper();
            DataSet dsPackage = new DataSet();
            dsPackage = objSQL.ExecuteDataset("AL_PackageType_List_Retrieve",
                                             objUtl.NumericEntry(Session["LocationId"].ToString()));
            gvPackage.DataSource = null;
            gvPackage.DataSource = dsPackage.Tables[0];
            gvPackage.DataBind();
            //dsPackage.Dispose();
            if (gvPackage.Items.Count <= 0)
            {
                lblMessage.Text = "No Package Details Found...";
                gvPackage.Visible = false;
            }
            else
            {
                gvPackage.Visible = true;
            }
        }
        catch (Exception ex)
        {
            lblMessage.Text = objUtl.GetErrorMessage(ex, this);
            lblMessage.Visible = true;
        }
    }

Hi Joby,

RadGrid does not support paging and CRUD operations with simple data-binding, so please replace it with advanced data-binding through the NeedDataSource event handler. The articles I linked to explain the differences between the two in more detail.
