q2 2009 radgrid: index [pagesize] is either negative or above rows count.

[Terry Hoiness]

After sorting with the radgrid then changing pages (or the reverse), I get: "index [pagesize] is either negative or above rows count."

The code is quite simple

    protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
        DataTable dt = dm.GetDtFromSQL(string.Format(SQLTemplate, ViewState["showID"]), "", ViewState["showID"].ToString(), false);
        if (dt.Rows.Count > 0)
        {
            DataView dv = dt.DefaultView;
            dv.RowFilter = ViewState["filter"].ToString();
            dv.Sort = string.Format("{0} {1}", ViewState["sort"], ViewState["order"]);
            RadGrid1.DataSource = dv;
        }
        else
        {
            RadGrid1.DataSource = null;
        }
    }

DISREGARD.  I was sorting the datatable on every NeedDataSource() call...
