    Hi all,

    I created RadCombox with  <headerTemplate> and <ItemTemplate>.
    Now I need to select all items by selecting "Check All" option .
    Can anyone tell how to add "check all" option for this.
    Note: I tried with EnableCheckAllItemsCheckBox="true" ,but it is not selecting all items .

    Hi Rev,

     
    Since you are using item templates you will have to use your custom code to check or uncheck all the checkboxes. Here is a sample code how such behavior can be achieved:

    <script>
             function OnClientClicked(sender, args) {
              
                 $telerik.$(".rcbSlide input:checkbox").attr("checked", "checked");
             }
         </script>
         <telerik:RadButton runat="server" ID="Rb1" AutoPostBack="false" OnClientClicked="OnClientClicked"></telerik:RadButton>
     <div>
         <telerik:RadComboBox ID="RadComboBox1" runat="server"
              AutoPostBack="true" 
           >
             <HeaderTemplate></HeaderTemplate>
             <ItemTemplate>
                 <asp:CheckBox runat="server" />
             </ItemTemplate>

    Hope this will be helpful.Greetings,
