Custom Button

Hi All,

I would like a button that inserts an Iframe with a predefined link. The reason I would like that is so that in Wiki, I can insert a menu on top of every wiki. When a user create a new page, all he would have to do is press the button to insert the menu (iframe)?

Any Idea?

PanelBar?

Hi!
Prometheus seems to be lacking PanelBar control. Can it be emulated with Sliding Pane? Do you have a example?

Thanks!

Creating Docks - Client Side

Hi there,

one of the examples for the RadSlider shows how to create objects in client side. Can we do the same with RadDock and other Prometheus controls?

<script> 

                function CreateSlider()  

                {  

                    var sliderProps = {  

                        Value : 50                          

        }  

                    var sliderEvents = {}; // we do not need events  

                    var elementToExtend = $get("ClientSlider"); // replace this element with a new RadSlider  

                    $create(Telerik.Web.UI.RadSlider, sliderProps, sliderEvents, null, elementToExtend);  

                }  

            </script>

Multi-Day Appointments without all day events

In the application I'm working on, we need the ability to show appointments that span multiple days. The recent service pack fixed the problem with the month view, but we're still having a problem with the week view.

If we specify an appointment that starts in one day and ends two days later, the middle day only shows up in the all day row. This is confusing the users since they percieve that the middle day is empty. Is there any way to force the appointment to show as an all day appointment in the middle days?

Thanks,
Chris

Using Window without WindowManager

Hey,

I noticed with your examples that you are using the WindowManager. In the overview of the new Window Control with Prometheus, you say you do not need the window manager. Is there anything specific I need to do in order to use it without the Window Manager?

I ran two test using the following code. It works when you have the Window Manager, but does not work without the Window Manager.

<script type="text/javascript">  

function openRadWindow(url, windowname)  

{  

    var oWnd = radopen(url, windowname);  

}  

</script> 

<asp:LinkButton ID="btnEditProfile" runat="server" Text="Edit Profile" OnClientClick="openRadWindow('../IT/EditProfile.aspx', 'Edit Profile'); return false;"></asp:LinkButton></span>  

<telerik:RadWindowManager ID="test" runat="server">  

<Windows> 

<telerik:RadWindow ID="testing" runat="server"></telerik:RadWindow> 

</Windows> 

</telerik:RadWindowManager>

Thanks,
Bob

Ajax Questions

I'm just starting to ajaxify the stuff that we already have working and I'm running into some weird things:

1. I cannot for the life of me get a javascript to force an ajax request from a AjaxPanel. I do this <%=radPnl.ClientID%>.AjaxRequest(null); and it always comes back with a script error that the object doesn't have that method. How do I get it to work?

2. Where did the timer stuff go that was in the original Telerik controls for setting timers? Right now I've made it refresh periodically using a microsoft timer inside the ajax panel which seems to work ok, but I don't think it's optimal. (and it won't display the loading panel.)

3. I'm looking for an example of ajaxifying a multipage. Basically I want to have a tab control that loads the pages dynamically. Further, I don't want the code that loads right now on the Page_Load of my user controls to fire at all until they are requested which is happening right now. I'm a little confused as to how this is supposed to work.

Thanks!

Tooltips never position correctly

I set my tooltip position to the top-left of my elements so that on mouseover the tooltip positions itself away from the element and allows room for the user to still right-click on the element to bring up a context menu. However, the positioning is really poor. I had to disable the callouts as they never lined up with the element, and the tooltips (particulary ones with more height) always seem to cover my element - i.e. drifting down and right. I wanted the bottom-left of the tooltip to be at the top-right of my element as per the examples in the "Positioning" section of the tutorial. I would expect this to happen if a tooltip opened close to the screen boundary but it seems to happen all the time. Is this a recognised problem and is there a workaround?
