Hi,
I am trying to put a form with a radcombox in a sticky tooltip.
This is the tooltipo that I want to use: Centred and Modal.

      
<telerik:RadToolTip runat="server" ID="RadToolTip2" Modal="true" Animation="Fade" Skin="Windows7"  HideEvent="ManualClose" 
         TargetControlID="Button_Add" Position="Center" RelativeTo="BrowserWindow" > 
    </telerik:RadToolTip> 
 

The radcombobox use the load on demand feature because it allows the user to look into a very large DB. this Combobox will send a postback when an element is selected.
<telerik:RadComboBox Skin="WebBlue" ID="RadComboBox1" runat="server" Height="190px" 
                                Width="250px"    
                                MarkFirstMatch="true"   
                                EnableLoadOnDemand="true"   
                                HighlightTemplatedItems="true" 
                                DropDownWidth="350px"   
                                ItemRequestTimeout="500"    
                                AutoPostBack="true"    
                                EnableViewState="true"     
                                OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"

The problem is that the RadComboBox is not loading anything, just empty.
When I put the same RadCombobox outside the Tooltip it works just fine.
Am I missing something?

Thanks for your help.
Mohamed

Hello Mohamed,

I am not sure how exactly you load the content of the combo box - with the provided code snippet there will not be anything loaded in the combo box. I also examine the tooltip declaration but I could not see anything that might be influencing the RadComboBox. That is why I strongly recommend to examine the ways to load on demand content in a RadComboBox below:

http://demos.telerik.com/aspnet-ajax/combobox/examples/loadondemand/automaticloadondemand/defaultcs.aspx

http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx

If the issue persists, please prepare a sample, fully runnable reproduction demo which has only a RadToolTip with the RadComboBox inside it configured the same way as in your original application (use a fake programmatic datasource for the combo box), open a new support ticket and send it to us along with detailed explanations and we will do our best to help.
