I'm persisting the GroupBy expressions for a grid. The grouping is set by the end-user.

I have a problem in that I have a column like this...

Now, when I save the GroupBy expression, I save the value returned by the GroupByExpression's .Expression property.

When I try adding that that as a new GroupByExpression when the user revisits the page, the GroupBy header displays "Name" rather than the column's defined HeadterText of "Template".

Now, I did try serializing the whole of the GroupByExpression, but when I tried deserializing it to recreate the object, it complained that Only Field object can be in the Frieds collection, or something like that.

So, to the question. How can I serialize the GroupByExpression so that I can recreate the grouping with a) the correct field and b) the correct header text for the item in the GroupBy area of the grid?

                </telerik:GridTemplateColumn>
            </Columns>

I use the Batch Edit Mode and in function SetEditorValue() I hide all the controls first and show only a specific one, but the RadDatePicker does not hide, i have tried everything and does not work. Can you help me please!

   function SetEditorValue(sender, args) {
       if (args.get_columnUniqueName() === "Valor") {
           args.set_cancel(true);
           //Obtem o conteúdo pretendido
           var container = args.get_container(), editarValor = args.get_value();
           //Esconde todos os controladores existentes na celula
           var rddlValor = $telerik.findControl(container, "boolValor");
           rddlValor.set_visible(false);
           var rtbValor = $telerik.findControl(container, "strValor");
           rtbValor.set_visible(false);
           var rnitbValor = $telerik.findControl(container, "intValor");
           rnitbValor.set_visible(false);
           var rnftbValor = $telerik.findControl(container, "floatValor");
           rnftbValor.set_visible(false);
           var rdpValor = $telerik.findControl(container, "dateValor");
           rdpValor.set_visible(false);
           //Obtem o ID do TipoValor
           var celulaTipoValor = sender.get_masterTableView()._getCellByColumnUniqueNameFromTableRowElement(args.get_row(), "TipoValor");
           var IDTipoValor = sender.get_batchEditingManager().getCellValue(celulaTipoValor);
           //Passa o valor para o respetivo controlador
           switch (IDTipoValor) {
               case "1":
                   rddlValor.set_visible(true);
                   if (editarValor === "Sim")
                       rddlValor.findItemByValue("1").select();
                   break;
               case "2":
                   rtbValor.set_visible(true);
                   rtbValor.set_value(editarValor);
                   rtbValor.focus();
                   break;
               case "3":
                   rnitbValor.set_visible(true);
                   rnitbValor.set_value(editarValor);
                   rnitbValor.focus();
                   break;
               case "4":

                   floatValor = (editarValor !== null) ? editarValor.toString().replace(".", ",") : "";
                   rnftbValor.set_value(floatValor);
                   rnftbValor.focus();
                   break;
               case "5":
                   rdpValor.set_visible(true);
                   dataValor = (editarValor !== null) ? new Date(editarValor.replace(/(\d{2})-(\d{2})-(\d{4})/, "$2/$1/$3")) : "";
                   rdpValor.set_selectedDate(dataValor);
                   rdpValor.get_dateInput().focus();

Hello, we  are using 2014.1.403.40 version.

My source was published 2 each server. also same source and version.

One server did working that I expected, but another server didn't work.

Scheduler display appointment  that title is user name on timeslot.

Correct working  should be display alphabetical sort for username

Incorrectly working server display  Steve, Jason, Hassan.

I have no idea, why same source shouldn't be same working just.

Could you let me know any idea?

   <MasterTableView  AllowPaging="true" AutoGenerateColumns="false"> 
    <Columns>
    <telerik:GridBoundColumn DataField="Inno_ID_Key" HeaderText="userid" Visible="true">

            SqlConnection sqlCon = new SqlConnection(strConnString);
            sqlCon.Open();
            SqlCommand CMD = new SqlCommand(" SELECT Inno_ID_Key from DimAhiEvent ", sqlCon);

            dr = CMD.ExecuteReader();
      
            radgrdidemo.DataSource = dr;
            radgrdidemo.DataBind();
           



        }
        protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
