Form refresh when using RadComboBox with checkbox inside

[johnson lim]

Hi,
I have a RadComboBox with 5 checkbox inside.When user click on the checkbox, my program will perform some business logic checking and feedback to user.

However the problem i face is, everytime user click on the checkbox, the whole page will refresh and all the gui need to reload again.
Even I have set not to refresh the whole page when user click on the checkbox. Below is my code.

<ajax:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server">
      <ClientEvents OnRequestStart="onRequestStart" />
      <AjaxSettings>
       <ajax:AjaxSetting AjaxControlID="chkPoCat">
             <UpdatedControls>
              <ajax:AjaxUpdatedControl ControlID="DdlPoCat" />
              </UpdatedControls>
       </ajax:AjaxSetting>

 <ajax:AjaxSetting AjaxControlID="DdlPoCat">
             <UpdatedControls>
                  <ajax:AjaxUpdatedControl ControlID="DdlPoCat" />
              </UpdatedControls>
       </ajax:AjaxSetting>

      </AjaxSettings>
  </ajax:RadAjaxManager>

  <ajax:RadComboBox ID="DdlPoCat" runat="server" Width="240px"  AllowCustomText="false"  EnableVirtualScrolling="true"  EnableLoadOnDemand="True" Text=" " OnClientKeyPressing="clickButton">
                          <ItemTemplate>
                              <asp:CheckBox runat="server" ID="chkPoCat"  oncheckedchanged="chk_CheckedChangedPoCat" AutoPostBack="True" Text='<%#Eval("ParamDesc")%>' />
                          </ItemTemplate>
                      </ajax:RadComboBox>

Can anyone help? I have search online for few days but no solution on this. HELP PLEASE !!

Hello Johnson,

Have you tired using the RadComboBox's CheckBoxes built-in feature? Using the CheckBox functionality you could still define templates while at the same time you could take advantage of the ItemChecked events on the server as well as on the client.

I hope this will help.
