how to get value from OnClientSelectedIndexChanging using OnItemsRequested in radgrid

[Dhamodharan]

I have radcombobox into my radgrid. i want selected index changed without post back.

using OnClientSelectedIndexChanging with OnItemsRequested. i got value from db. but it is not assigning into label.

here i attached my code

 <telerik:RadComboBox ID="ddlCoverage" AutoPostBack="false" Width="110px" AppendDataBoundItems="true"
                                                runat="server" OnSelectedIndexChanged="ddlCoverage_IndexChanged"  DataTextField="cvg_typ_code" OnClientSelectedIndexChanged="LoadDdlCvg" OnItemsRequested="ddlCoverage_OnItemsRequested"
                                                DataValueField="pln_cvg_id">                                               
                                            </telerik:RadComboBox>


function LoadDdlCvg(combo, eventArqs) {
                      var item = eventArqs.get_item();
                      $find(combo.get_id()).requestItems(item.get_value(), false);            
                  }

   Protected Sub ddlCoverage_OnItemsRequested(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs)
        Dim rcCoverage As RadComboBox = DirectCast(sender, RadComboBox)
        Dim l_pln_id, l_pln_cvg_id, ben_EE_amt, ben_ER_amt As Double
        Dim item As GridDataItem = CType(rcCoverage.NamingContainer, GridDataItem)             
            l_pln_cvg_id = e.Text                   
            Dim lblEEContrib As Label = item.FindControl("lblEEContrib")
            Dim lblERContrib As Label = item.FindControl("lblERContrib")             
                lblEEContrib.Text = String.Format("{0:c}", ben_EE_amt)           
                lblERContrib.Text = String.Format("{0:c}", ben_ER_amt)        
       
    End Sub

Bold value comes from db. but it's not assigning into label
Please give me a tips for this is one.

Thanks in advance,
Dhamu.

Hi Dhamu,

It seems that you are mixing client with server-side events. If you want to load the RadComboBox items on demand on the client, you can consider using a web service for this purpose like shown here:
ADO.NET Service
WCF Web Service
