RadGrid with Upload In grid Generates PageRequestManagerServerErrorException

I have a RadGrid with an upload copied from the example. When the cancel, edit or delete buttons are pushed I get a Microsoft JScript runtime error with the following data:

Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I have tried several work arounds but none of them work.

Filter Operator dropdown not displaying at the expected location

Hello,

Please take a look at the attached screenshot. When I click on the filter operator selector (this is, the place where I can pick if I want the field to be EqualTo, NotEqualTo, GreaterThan, etc.) the dropdown centers itself in he middle of the screen, instead of showing right down the Filter component expression being entered. This happens also when I click on the Field selector. Is this a CSS issue? please advice, thanks!

500 error when selecting an item

I have a RadComboBox that is populated on demand with a web service with items based off what the user types. It works fine with a basic string as the text value when I add a RadComboBoxItemData object to the array that I pass back with the web service. I would like to have a template format when the RadComboBox is opened though. For example, a name with a formatted address that is a different color than the title and someone dynamically formatted based on what fields exist for each record. I didn't see an example, so I tried to generate a few HTML tags to handle that. It displays fine when expanded, although it has the tags for the textbox area. It would be nice if I could just have the name in the textbox, but the name and formatted address when the RadComboBox is open. When I select one of the items I get a server 500 error. In the event viewer, it states that "A potentially dangerous Request.Form value was detected from the client ". Is there some other way that I should be doing this? Is the functionality I am looking for even possible right now with the RadComboBox?

Schedular save error

I have bound a scheduler to the data source using sqldatasource, following instruction from here http://www.telerik.com/help/aspnet-ajax/scheduler-declarative-data-binding.html, except I did not assign any resources. The code is given below at the end.

Problem is when I press the Save in editor I get below error;

Invalid object passed in, member name expected. (46): {"command":"InsertAppointment","appointment":{,"Subject":"776","Description":"","Resources":[],"RecurrenceState":0},"startDate":"201108020000","endDate":"201108030000"}
