[Solved] Menu under custom control in Firefox

I am using a radmenu on the same page as a custom control. The custom control shows a PDF reader in the web page.
In IE 6 and 7, the menu choices will overlay the custom control when you roll the mouse over them as expected. In Firefox 3.0, the radmenu choices open but they are underneath the custom control.
Here is what the HTML looks like:

    
                <asp:Panel ID="pnlShowPDFDocument" runat="server" CssClass="NonCatalogData"> 
        
                    <telerik:RadMenu ID="RadMenu1" runat="server" Width="1000px" > 
        
                    <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
                    <Items>

Virtual scrolling problem

I'm evaluating Telerik's Rad Controls for my company. We are currently using ComponentArt but aren't satisfied with it. I've been looking into the Rad controls. I really like what I've been able to accomplish using the RadControls with minimal effort. However, I'm having trouble getting the virtual scrolling to work at all. I can get the scroll bar to appear. If I use paging the scroll bar will work for a single page, but not for the whole returned data set and it will not automatically go back and pull the next set of data like the yahoo-style example. I'm sure I'm doing something wrong but haven't figured it out.

I'm using .net 3.5 and c# and asp.net AJax Rad Grid Control. My datasource is a collection List.
I've been using the demos: Virtual scrolling and paging as guidance. My final goal would be to have my app use the Yahoo-style scrolling. However, I'd like to get both types to work.

Any guidance on this would be appreciated.

Drag & Drop with Nodes Templates

I defined a RadTreeView using a template for nodes.
Every node must contain a dropDownList and a Label, filled from a DataTable.

I have 2 problems:
1) When i try Drag & Drop nodes i get an error derived from the DropDownList;
2) if i don't put the DropDownList in the Template (so only the Label) after the drag & drop i lost the template and data fails.

How can i solve this 2 problems?
Above the code.
Thanks a lot.

header within header in grid

i want to have a grid that has a format like this
                             Student 1                                            Student 2
              Point            Total           percent           Point          Total          Percent
rank
score
sport
Total

so every three columns there is a student header, also each column has its own header, and the rank, score are also header. and last is total of all the points for column point. can we do this with telerik grad?

[Solved] F2 not enter edit mode

Hi
I have a rad tree with allowEdit = true, I add this line of code

    
            protected override void OnInit(EventArgs e)  
        
                    {  
        
                        base.OnInit(e);  
        
                        RadTreeView1.NodeClick += new Telerik.Web.UI.RadTreeViewEventHandler(RadTreeView1_NodeClick);  
        
                    }

Now, if I select a node and press the F2 key the node doesn't enter an edit mode.but if I select a node and click on it second time the node enter a edit mode.
If i remove "RadTreeView1.NodeClick +=..." F2 work fine.

any idea or work around to solve it will be great because I have to use nodeClick

Thanks

when does the TimeSlotCreated event get fired?

Hi,
I am trying to set backcolor of every timeslot according to working hours in a day. This means that if the slot comes between 0800 hrs and 1700hrs, the backcolor of the timeslot is white and if it falls beyond the given range i'm setting the backcolor to gray. This I am doing in the RadScheduler_TimeSlotCreated event. But it is not working.

protected

void RadScheduler_TimeSlotCreated(object sender, TimeSlotCreatedEventArgs e)

{

if (e.TimeSlot.Start.Hour < 8)

{

e.TimeSlot.CssClass =

"extended_business_hrs";

}

I am not even sure if the event is getting fired or not

_EVENTTARGET is null or not an object

hi

i have a webcustomcontrol that dynamically adds a file upload, a submit button, an image and various links to update the image via Ajax. all of these are wrapped in an RadAjaxPanel. The ajax bits owrk fine and the image gets updated and all via ajax. The upload button is registered with the ScriptManager on the parent page (which is passed into constructor of cusotmcontrol) as being a postback control rather than an ajax callback control - when user hits upload gets the above javascript message - any ideas?

thanks
