Questions on UI for ASP.NET AJAX Forum

Probably a really obvious mistake, but I have been scratching my head for a couple of hours now. I can't seem to get javascript to find my tree view, I started off in a splitter area, and then took it out, and have now created the most basic page I can to try and find a tree view with the Javascript API.

When I run this I get a Javascript error telling me

"Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET CLR 1.1.4322; InfoPath.2; OfficeLiveConnector.1.3; OfficeLivePatch.0.0)

Message: 'tree' is null or not an object
Line: 67
Char: 18
Code: 0"

So it's not finding the tree, never mind the nodes. Any suggestions would be gratefully received.

Change Appointment font style

I am trying to change the font size and weight of appointment text shown in scheduler from code behind but it is not taking any effect.

protected void Page_Init(object sender, EventArgs e)

{

List<Appointment> list = (List<Appointment>)this.VacationScheduler.Provider.GetAppointments(this.VacationScheduler);

foreach (Appointment p in list)

{

p.CssClass = "boldy";

p.Font.Italic = true;

}

CSS:

-------

.boldy

{

font-style:italic !important;

font-weight:bold !important;

}

</style>

It is not taking effect.

Any suggestions?

Possible to add onmouseover to appointments?

I'd like to implement my own version of a popup when the user mouses over an appointment on the schedule control. I've tried adding it to the attributes collection on both the Appointment object and the AppointmentControl object, but neither of these has worked. Is there a way to add this attribute to appointments?

radGrid paging shows empty page

Hi,
I have a Rad Grid with enableviewstate=false. It calls all the methods, so it does get data at the backend. I debugged and check all the methods. As there is no view state so i have to generate the Grid and then fill it with new data on pageindexchnaged. It does call all the methods in proper way.
Issue is that it does not show anything, not even header or page, does even say that it does not have data like it usually do first time. I am working inside MS CRM 4 IFrame. SO, no viewstate on the whole app. It may be issue due to ajax ?
So, what could go wrong ?

Regards,

Osman

Web service, OnItemDataBound, No Postback

I am using a radgrid to display some data, and I am trying to figure out which method would be better to use.
Here are my preferences:
I would like to use a webservice to retrieve the data.
I would like to be able to use the server side OnItemDataBound event to process the data, changing date formats, enabling an image column, etc.
I would like to use some form of an AJAX request for the paging and sorting without the postback flashing.

Can I accomplish this with the radgrid?
