    Hi!

    How to choose radcombobox1 and then clear radcombobox 2  For radcombobox in radgrid

    • I try to put javascript, but it does not work, and then find that find combobox2 not found.
    • Here is my jquery ajax function:

    function OnClientSelectedIndexChanged(sender, eventArgs) {
     
                   var SenderId =  sender.get_id();
                   var RadTextBox1 = $("#" + SenderId).get(0);
                   var RadTextBox2 = $("#" + SenderId.replace("combo_Examtion", "combo_ExamtionCount")).get(0);
                   //// for telerik /radcontrols
                   var RadTextBox2 = $telerik.findTextBox(SenderId.replace("combo_Examtion", "combo_ExamtionCount"));
                   
     
               }
    <telerik:GridTemplateColumn HeaderText="ข้อสอบ" HeaderStyle-Width="200px" UniqueName="NameExaminationID" DataField="NameExaminationID">
     
                               <ItemTemplate>
     
                                   <asp:Label runat="server" ID="lblNameExaminationID" Text='<%# Eval("NameExamination")%>'></asp:Label>
                               </ItemTemplate>
     
                               <EditItemTemplate>
     
                                   <div style="width: 190px; float: left;">
                                       <telerik:RadComboBox ID="Radcombobox1" runat="server" AllowCustomText="True" Filter="Contains" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged"
