Script

<script type="text/javascript">
          function FilterCreated(sender, eventArgs) {
              var filterMenu = sender.get_contextMenu();
              filterMenu.add_showing(FilterMenuShowing);
          }
          function FilterMenuShowing(sender, eventArgs) {
              var filter = $find("<%= RadFilter2.ClientID %>");
              var currentExpandedItem = sender.get_attributes()._data.ItemHierarchyIndex;
              sender.findItemByValue("Between").set_visible(false);
              sender.findItemByValue("DoesNotContain").set_visible(false);
              sender.findItemByValue("EndsWith").set_visible(false);
              sender.findItemByValue("GreaterThan").set_visible(false);
              sender.findItemByValue("GreaterThanOrEqualTo").set_visible(false);
              sender.findItemByValue("IsEmpty").set_visible(false);
              sender.findItemByValue("IsNull").set_visible(false);
              sender.findItemByValue("LessThan").set_visible(false);
              sender.findItemByValue("LessThanOrEqualTo").set_visible(false);
              sender.findItemByValue("NotBetween").set_visible(false);
              sender.findItemByValue("NotEqualTo").set_visible(false);
              sender.findItemByValue("NotIsEmpty").set_visible(false);
              sender.findItemByValue("NotIsNull").set_visible(false);
              sender.findItemByValue("And").set_visible(false);
              sender.findItemByValue("NotAnd").set_visible(false);
              sender.findItemByValue("NotOr").set_visible(false);
              sender.findItemByValue("Or").set_visible(false);
              }
          }
      </script>

Aspx

<telerik:RadFilter runat="server" ID="RadFilter2" FilterContainerID="RadListView1"
   ClientSettings-ClientEvents-OnFilterCreated="FilterCreated"
      ExpressionPreviewPosition="Bottom">
   <FieldEditors>
      <telerik:RadFilterTextFieldEditor FieldName="ItemName" DisplayName="ItemName" DataType="System.String" />
              <telerik:RadFilterTextFieldEditor FieldName="ItemCode" DisplayName="ItemCode" DataType="System.String" />
  </FieldEditors>
 </telerik:RadFilter>

Rad Ajax Update:

<telerik:AjaxSetting AjaxControlID="RadFilter2">
  <UpdatedControls>
     <telerik:AjaxUpdatedControl ControlID="RadListView1" LoadingPanelID="RadAjaxLoadingPanel1" />
      <telerik:AjaxUpdatedControl ControlID="RadFilter2" LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
 </telerik:AjaxSetting>

Code

Protected Sub RadFilter2_AppyExpressions(ByVal sender As Object, ByVal e As RadFilterApplyExpressionsEventArgs)
       Dim provider As New RadFilterListViewQueryProvider(New List(Of RadFilterGroupOperation)())
       provider.ProcessGroup(e.ExpressionRoot)
       RadListView1.FilterExpressions.Add(provider.ListViewExpressions(0))
       RadListView1.Rebind()
   End Sub

 when i try to select the menu of the filter control that time am getting the error like "Microsoft JScript runtime error: Unable to get value of the property 'set_visible': object is null or undefined"

Please fix my issue...

Hi Prassin,

Can you specify which version of RadControls for ASP.NET AJAX you are using? If you are not using the latest version, please download it and see if the problem still persists.
