RadMenu using the WebService

[Guo Huang]

Hi

I am using RadMenu and binding data with WebService. i would like to call the webservice (or bind data on the clientside) when the radmenu is loaded instead of mouseover, can i do that?

I have done a lot of researches before i ask this question, but i don't see any examples to preload radmenu with webservice.

Thanks

Hello Guo Huang,

Currently there is no public API which would allow you to preload the items. However you can use the private
_loadChildrenFromWebService method of the RadMenuItem client-side object. When the page loads you can traverse the items and call that method:

<script type="text/javascript">
function pageLoad() {
      var menu = $find("<%= RadMenu1.ClientID%>");
      for (var i = 0; i < menu.get_items().get_count(); i++) {
             var item = menu.get_items().getItem(i);
             item._loadChildrenFromWebService();
      }
}
</script>

Hi Albert

if i want to bind the menu using the following code, what javascript method should i call to populate data from the wcf service?

<tlrk:RadContextMenu ID="RadMenu2" runat="server" Flow="Vertical" Skin="Office2007" EnableViewState="false">

<Targets>

<tlrk:ContextMenuElementTarget ElementID="view1" />

</Targets>

<WebServiceSettings Method="LoadData" Path="GetRadMenu.svc" />

<DataBindings>

<tlrk:RadMenuItemBinding Depth="0" ExpandMode="WebService" />

</DataBindings>

</tlrk:RadContextMenu>

Thanks

Hello,

Currently RadMenu and RadContextMenu support Web Service loading only for sub-items. The root items must be created manually.

Root items can be manipulated on the client-side and you can manually populate them from a WS, but the easier option would be to place them in a sub-item. You can then use the code snippet to preload them if needed.
