RadAjaxLoadingPanel only firing once after entering page.

I have the following RadAjaxLoadingPanel that I am using to show a loading image when doing a search.

<asp:Panel ID="PanelUpdateProgress" runat="server">

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" MinDisplayTime="2000" >

<asp:Label ID="LabelLoadingText" CssClass="labelloading" runat="server" Text="Loading Data..."></asp:Label>

</div>

</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">

<telerik:AjaxSetting AjaxControlID="buttonSearch">

<telerik:AjaxUpdatedControl ControlID="divTitle2" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

</asp:Panel>

When I first come into the page and click the search button(buttonSearch), which is included in a separate div not shown here with other code, the loading image comes up covering the whole page just as I would like. However, when I do additional searches without leaving the page, the search itself executes, but the loading image does not come back up. Am I missing a property that must be set in order to have the loading image come up again.

Thanks for any help that anyone may have.

error with url mapping

In a website I'm developing, I'm mapping URL paths to specific files with query strings. This was working great with the non-Ajax controls (both Q1 and Q2) but when I put in the AJAX Manager, or Panel, it breaks. Each time a page starts the request, an error will pop up saying the following:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 404

If I replace <telerik:RadAjaxPanel></telerik:RadAjaxPanel> with <radA:RadAjaxPanel></radA:RadAjaxPanel> everything goes back to working as expected.

Is there a way to get the AJAX version to work with URL mapping like the non-AJAX version? I can use the standard <radA:RadAjaxPanel> but I'd like to swap it out if at all possible.

Thanks!

HeaderDateFormat

Dear Telerik-team,

When we installed the latest hotfix (2009.2_817), it seems that the HeaderDateFormat became broken.

They look like this in the TimeLineView: http://bart.nimio.info/images/fora/scheduler3.JPG, while we have the HeaderDateFormat set to "H:mm" (also notice the alignment of the two appointments. One is always standing a little lower than the other one. Would it be possible to keep all the appointments on the same level, except for the ones that overlap eachother?)

The same problem for the WeekView: http://bart.nimio.info/images/fora/scheduler4.JPG (HeaderDateFormat="dd/MM/yyyy").

Rad grid Command Events not firing

I have this strange problem. I have been using telerik controls for about 1 year now. i used extensively Rad Grid, never had problems.
I am migrating a project from .net 1.1 to 3.5 version. I created a new usercontrol which contains Rad Grid. on hitting Commnad Item "Add new record" which is automatically created. it is hitting initInsert Command, but when i enter the data and press insert or change the data and press update its not hitting item command. I have checked it many times.

            End Class

There is no code as of now. but i am not able to hit the break points on command events to go forward.
Any help would be appreciated.
Thanks

[Solved] validation display differences

I noticed in the validation example found here:
http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/validation/defaultcs.aspx

That the display is different in IE6 vs firefox 3.0

The following steps illustrate the point
1. Use the picker to choose a valid date.
2. Edit the date in the field so that the year has 5 digits
3. remove focus form the field
The result is that in firefox, the entered data is read, a read border appears around the input field, an error icon is displayed within the field and an error message is shown. If IE, the only thing shown is the error message. Is there away to get these to behaving consistently? The firefox option is my preferred display.

Thanks

are we all mad?

I'm sorry but I just can't get my head around what Telerik is trying to do to the world. I just tried the Visual Skinning tool and, though it looks flashy, ... what's this all about?

Look:
I don't want to create "custom skins" for anything. I want the code that telerik generated to simply BE VOID OF STYLING. Nothing. Rien. Nada .. and whatever.

I want it to have NO BUILT-IN CLASSES, NO INLINE STYLES. I want it to know exactly what its supposed to look like by having it react to the CSS that already exists on its page. I want telerik grids to look JUST LIKE the non-telerik grids on the rest of the website.

I thought / hoped we were rid of the pre-thunked (as in thinked) "we know better than you" nonsense that plagues microsoft controls (gridview, formview, etc). But no we see Telerik has taken this mad idea to a whole new level ..

the gods of the internet bless MVC .. and death to blobbous unbeliveably overcomplex self-styling non-confirming controls.

Its only because my company is forcing me to use telerik that, unfortunately, I continue to use telerik.

RadAjaxManager ignores first click and does a postback on second click

I have a RadAjaxManager wired up to a button control that upates an asp:panel. Ignored meaning that the postback occurs and the button click event handler fires, but the page isn't uploaded. This is inside a user control that is hosted inside an aspx page. The ajax settings are set inside the usercontrol itself.

What's even wierder is that the loading panel displays. It just won't update the panel.
