Modify grid filter menus from client side

[Lynn]

I need to modify the filter menus on the grid selectively by data type (and possibly even by specific data column).  There is some discussion of this on http://www.telerik.com/help/aspnet-ajax/grid-reducing-filtermenu-options.html , but there is no actual example of the client javascript shown.  I am successfully modifying the filter menus from the server side, so I understand the concepts, but I don't have the javascript code samples to understand the properties and values that I have access to on the client side.

Any simple examples that anyone might have would be immensely helpful.

Thanks in advance!

Hello,

The help topic you have pointed out has a JavaScript part that shows how to hide some of the filter options based on specific type. You need to click on the tab labeled JavaScript(check the attached image file).

Here is the code from the help topic:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
var column = null;
function MenuShowing(sender, args) {
  if (column == null) return;
  var menu = sender; var items = menu.get_items();
  if (column.get_dataType() == "System.String") {
    var i = 0;
    while (i < items.get_count()) {
      if (!(items.getItem(i).get_value() in { 'NoFilter': '', 'Contains': '', 'NotIsEmpty': '', 'IsEmpty': '', 'NotEqualTo': '', 'EqualTo': '' })) {
        var item = items.getItem(i);
        if (item != null)
          item.set_visible(false);
      }
      else {
        var item = items.getItem(i);
        if (item != null)
          item.set_visible(true);
      } i++;
    }
  }
  if (column.get_dataType() == "System.Int64") {
    var j = 0; while (j < items.get_count()) {
      if (!(items.getItem(j).get_value() in { 'NoFilter': '', 'GreaterThan': '', 'LessThan': '', 'NotEqualTo': '', 'EqualTo': '' })) {
        var item = items.getItem(j); if (item != null)
          item.set_visible(false);
      }
      else { var item = items.getItem(j); if (item != null) item.set_visible(true); } j++;
    }
  }
  column = null;
}
function filterMenuShowing(sender, eventArgs) {
  column = eventArgs.get_column();
}
</telerik:RadCodeBlock>
