Custom User Control in ToolTip

Hi, I am trying to use RadToolTipManager to create on demand tooltip content which is dependant on the value of a particular column on mouse over.... as a starting point I am attempting to recreate as much of the example project - (http://demos.telerik.com/aspnet-ajax/tooltip/examples/loadondemand/defaultcs.aspx) in my own as possible. However I'm getting a ' Type 'ProductDetails' is not defined ' error in the following line of the code behind:

Dim details As ProductDetails = DirectCast(ctrl, ProductDetails)

I have tried putting the ascx file in my app_folder, the root, I'm pretty sure I've got all the relevant imports right and registrations at the top of the aspx file... am probably missing something obvious but can't figure out what...

Thanks in advance,

Rudie

Return argument when close (X) clicked

Is there a way I can capture the click of the 'X' close button from within the RadWindow, so I can set a specific argument value to be passed back to the parent window? From what I've seen, the suggested solutions have been to check for a null argument on the parent side which would indicate the X close was used. I want to pass an argument back (such as 'updated' or 'notUpdated') so I know whether to refresh a main grid control based on the actions performed within the window. Thanks.

Integrate RADChart into SharePoint 2010

Hi Telerik,
I tried to integrate the latest assemblies to SharePoint 2010. I follows the steps by adding safe control in web.config,

<SafeControl Assembly="Telerik.Web.UI, Version=2010.3.1317.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Charting" TypeName="*" Safe="True" SafeAgainstScript="False" />

I also add the httphandlers in web.config

<httpHandlers><br> <add path="ChartImage.axd" verb="*" type=

"Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2010.3.1317.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"

validate="false" /><br> </httpHandlers><br>

In my C# code, i also disabled the Session and set the temporary files where the web application have full permission to writes to that file(local administrator right).

After all done, when i tried to generate my chart, it throw exception as attached.

Kindly advise.

Regards.

hierarchical grid

I have requirement for hierarchal data grid. I'm binding the grid's datasource with a collection.
Each of the item within that collection has another collection as a Property.

Is there a way to bind the grid in such a way that , it automatically takes the inner collection as datasource for DetailsTable,
whereas the outercollection as datasource for MasterTableView ?

The telerik eg., i have seen, have datasource provided exclusively for both MasterTableview as well as Detailtable and the relation between them specifed using ParentTableRelation.

In my case, i have the relation between master & detail maintained in my collection. So binding the grid in NeedDatasource event and specifying the DataMember property declaritively should work.
let me know if you think i'm missing something ,
I donot wish to maintain two different datasource , as i have lot of grid operations.

multiline radTextbox doesn't accept ENTER key

I have the following multi-line textbox.

    
            <telerik:RadTextBox ID="txtComment" runat="server"  
        
            ValidationGroup="CommentValidation" CausesValidation="True" MaxLength="4096"  
        
            Skin="Black" Width="450px" TextMode="MultiLine" Height="150px" AcceptReturn="True" />

I want to be able to start typing and when pressing the ENTER key I want to go to the next line. This won't work because now it will trigger the validation of the form.

I tried the solution from this (winforms) thread but that doesn't seem to work here.
How can I fix this?

(I am using the radEditorProvider (2008.2723) in DotNetNuke 4.8.4)
