Appointment styles

Hi

I need a requirement like ,I need to show a particular duration having appointment in a particular color.I mean I dont want to show the appointment name or I dont want to see it like a projected section.I just want to show a light green color to indicate that an appointment has beed scheduled in the particular duration.

For eg : If an appointment is given for 9 to 9.20 I dont want to show it as a projection.I just need the section as such empty ,but with a different colour.Just to indicate that the particular timing has an appointment scheduled.

I searched a lot .But all search ends with giving cssclass/colour to the appointment given.I dont want that type.I just want to show the given appointment duration with different colour.I dont want to show a projected appointment block.Just need a colour change in the whole duration or time slot.This must be shown whether the user selects day,week or month type view.

Any help is appreciated..
Regards
Chinnu :)

RadPanelBar, ViewState off and PostBack problem

Hi
My app has ViewState disabled.
I have a panel bar with multiple items. Depending on some server side logic, I may hide some panel items.
The PanelBar loads fine.
However, on postback the wrong panel item opens.
Let's say I have 5 panel items and the server side logic hides the first one.
If I click Edit on the 4th item, on postback the 3rd item would open.

In the example below, no panel would be open on postback.
How can I fix it?

Thanks
Chen

Upload.UploadedFiles empty after failed validation fails

Server-side validation finds an error in some other user's entries when they attempt to upload a file they've selected.

After the PostBack, the Upload file list is empty again. How do I preserve the list so the user need not enter it again? Do I have to programmatically save and restore it myself?

RadTreeView.DataBind() not working

The data binding event in this code isn't working any longer. I was testing a custom node template and using the code from this page (add and edit templates Runtime), but then removed all the code specific to the custom node template. At that point, the data stopped binding. I have added the code back, moved all of it to another page, but the data binding event doesn't seem to fire. Even with all the test code from the linked page above in my page, if I set a breakpoint in the DataBinding function it never gets hit. If I manually place a RadTreeView on the .aspx page it will display, but anything set on the server side will not.

I have checked to make sure List used to populate the tree has data, and this line (radTree.DataSource = treeNodes) works correctly. But the databind is still failing.

Any suggestions?

Thanks,
Peter

Update:
From additional digging and messing around, the problem relates to converting a Guid to a string to be used as the ID field. I'm not sure why it won't accept the Guid as a string, but using an int instead of string fixes the problem. Any reason convertinting a Guid to a string would cause the data to fail to bind without any errors?
