Hi,

 I have a SplineChart displaying a monthly number of customers. Now I'd like to have a tool-tip showing for each month the increase or decrease of customers since previous month. 

I've seen this page : http://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/clienttemplates/defaultcs.aspx, but since my telerik version is outdated (2012.3.1016.35)  I can't use <ClientTemplate> token inside of  <TooltipsAppearance>  </TooltipsAppearance>.

Instead I used :
 <TooltipsAppearance  ClientTemplate = "#=dataItem.MonthlyIncrease#"    BackgroundColor="Red"> </TooltipsAppearance>

Where MonthlyIncrease is a column of the dataTable binded to my chart. However this isn't working, the tooltip only show the monthly number of customers, not the increase (and the background is still white). 

Thank you very much for your help,
Pierre. 

Bellow more of my code:

 <telerik:RadHtmlChart runat="server" ID ="SplineChartVehiculesSixMois" Skin="Simple" Transistions = "true" ToolTip = "true">

    <PlotArea>

        <Series>                                     

            <telerik:BarSeries>                                         

                <TooltipsAppearance  ClientTemplate = "#=dataItem.NombreVehi#" BackgroundColor="Red">  

                </TooltipsAppearance>

            </telerik:BarSeries>

         </Series>

     </PlotArea> 

</telerik:RadHtmlChart>

I have a RadPanelBar inside of a RadAjaxPanel. When an item is clicked on the RadPanelBar, I dynamically load a user control that uses a ModalPopupExtender. After a button is clicked on the user control and it causes a postback, everything works as intended and I can click another item on the RadPanelBar and everything works. When the user control is closed by the CancelControlID property of the ModalPopupExtender however, it doesn't cause a postback and the next time I click an item on the RadPanelBar, the RadAjaxLoadingPanel persists.

What the page looks like on load before any clicks: http://i.imgur.com/drnCcNO.png

What the rad panel bar looks after click on an item: http://i.imgur.com/czikveQ.png

Modal Control is loaded: http://i.imgur.com/rDT07Yw.png

After Modal control is closed without causing a postback, when clicking on an item in RadPanelBar again, it seems to be even more dim: http://imgur.com/YZNmRpM

 Now when user control is loaded again, the loading panel persists: http://i.imgur.com/TAXnRH4.png

We are using telerik old version which was using dll of rad controls.Now we are upgrading these controls to latest version of telerik and getting  skin's defined name issue i.e.previously which skin is used after updating dll it shows error skin name(exp. Skin="Arrows/3DBlueAppt" ) does not exits. 

My following code is not working , So please let us know How we can fixed this issue.

on aspx page:

<telerik:RadTreeView ID="rtvTopTreeview" Skin="Arrows/3DBlueAppt"  AutoPostBackOnCheck="False"
                                                                                                AfterClientCheck="AfterCheck" CheckBoxes="true" runat="server" AutoPostBack="True"
                                                                                                OnNodeClick="rtvTopTreeview_NodeClick">
</telerik:RadTreeView>

On .cs page:

rtvTopTreeview.imagesBaseDir= "~/RadControls/TreeView/Skins/Arrows/3DBlueAppt";​              

also it shows error that rtvTopTreeview does not contain a definition of imagesBaseDir.

please help .

I am just getting started with learning the Telerik products and I see there is info on Radgrid for ASP.net AJAX which indicates it is the newest version.  How can I tell which version I am using so I don't waist my time reading documentation on the wrong product.

Thanks

Perry

How do I control a RadButton's visibility state from the codebehind?

For example, if a user is not yet logged-in, then I want to hide the logout button.
