Hi,

I am facing the following issue. When I use this approach to bind data on clientside, the datalist is rendered on pageload:

<telerik:RadListView ID="ListViewCarImages" runat="server" AllowPaging="false" PageSize="999">
  <LayoutTemplate>
    <div id="listView">
      <div id="items">
      </div>
    </div>
  </LayoutTemplate>
  <ClientSettings>
    <ClientEvents />  
    <DataBinding ItemPlaceHolderID="items">
      <ItemTemplate>
...
      </ItemTemplate>
      <SelectedItemTemplate>
...
          </SelectedItemTemplate>
          <EmptyDataTemplate>
           ...
      </EmptyDataTemplate>
          <DataService Location="~/AluWebService.asmx" DataPath="CarsImagesList" />
        </DataBinding>
  </ClientSettings>
    </telerik:RadListView>


but when I choose this approach, no data is rendered at all though the data is sent over the wire as seen using httpfox:


            <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
                <Scripts>
.....
                </Scripts>
                <Services>             
                <asp:ServiceReference Path="~/AluWebService.asmx" /> 
                </Services>
            </telerik:RadScriptManager>

and

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
  <script type="text/javascript">
      function pageLoad() {
          listView = $find("<%= ListViewCarImages.ClientID %>");
          var xyz = AluWebService.CarsImagesList();
          listView.set_dataSource(xyz);
          listView.dataBind();
      }
</script>
</telerik:RadCodeBlock>

any idea why the second approach does not work?

I am using Q2 2011 and having some issues with the images for Tabs.
On Page_Load, I am adding tabs to a RadTabStrip. The TabStrip is in an RadAjaxPanel with EnableAjax set to true.




When the page loads, the tabs look great and the images are displayed correctly. The first tab is selected by default. When I click on another tab, the callback occurs and I handle the TabClick server event. During the callback, the tabs are not modified at all. When the page comes back, the images are now broken and the paths have changed.

So I am on a DNN site, on an edit page. The URL of the page is: http://localhost/MyProject/Orders/tabid/54/ctl/EditOrder/mid/363/Default.aspx

After the page loads, the URL of the image is
http://localhost/MyProject/DesktopModules/MyModule/images/ok.gif

After the callback, the URL of the image is
http://localhost/MyProject/Orders/tabid/54/ctl/EditOrder/mid/363/DesktopModules/MyModule/images/ok.gif

Any reason for the change in the ImageURL when the tabs werent modified during the callback? Am I missing something?

Also, if I disable Ajax, the Images work correctly and the ImageURL does not change.

I've been searching the documentation and the forum for a while for this, but haven't been able to find any solid information...

I have an object which contains some fields and a dictionary - I want to bind each value in the dictionary to a column in a radgrid.  I don't know what these keys/values will be until the item comes back, and they'll change depending on the source of the query.

I can create the columns dynamically without a problem, but I need a way to bind their DataMember to the dictionary...what's the best way to achiever this?

Hello,
I'm trying to change the colors (palette) of the skin "telerik".
But nothing seems to work.
Any Ideas ?

Hi all,

I'm a complete beginner with Telerik so I hope I explain this right.  

I have a RadMenu set up where you can mouseover a RadMenuItem and it calls an AJAX method to fetch a description, which then gets displayed in a label at the bottom of the menu.  It's something along the lines of this Telerik demo with the map, except the event is onmouseover and not onclick.  This all works great. 

However, you can imagine if someone is mousing down a menu of say 20 items, you only want the Ajax call to fire when the user rests on a particular menu item e.g. for say at least 0.25 seconds.  That way I'm not sending 20 Ajax calls off unnecessarily.

Is there a way to delay the firing of the Ajax call?

Hi,

I have a RadFilter control hooked up to do advanced filtering on a RadGrid. When attempting to apply a filter on a column which contains NULLS in the DB, I get the infamous "Object reference not set to the instance of an object" error. Since I cannot change my database structure, and the Nulls are required, is there anything I can do to allow my RadFilter to filter on these columns?

Best Regards,
Landon
