[Solved] Sorting: NullReferenceException

Hi,

my grid displays - for example - organization units: OrgUnit objects. The OrgUnit class has a property "Manager" which contains an instance of the class "Person". This class has, in turn, a property named "FullName".
I want to display names of managers in one of the grid's columns. I bind this column with: "Manager.FullName". And it works perfectly - event for units with no manager.
Then, I want to sort my grid by this column. I put SortExpression="Manager.FullName". It works - but fails (NullReferenceException) when any of displayed units has no manager.
I understand that "Manager.FullName" can raise this exception when "Manager" is null but when displaying data it doesn't.
Can I solve this problem any way?
The workaround: define a special property "ManagerFullName" (return Manager == null ? "" : Manager.FullName) is not acceptable.

RadSplitter width and height not working after upgrade

I had an application, with an outlook sytle menu. It was working fine until upgraded the latest version of RadControlers.

Rad Grid printing losing data

Ok, I am working with a web part that is used in multiple place in our code for reports. The web part has a RadGrid on it. The grid itself is set to take up to 100% of the container it is in. The issue I am having is that for some reason on one of the reports when we print it out or do a print preview, the grid headers and about 10 to 15 rows of data are missing. The first page of the print out has the content above the grid printing and the second page starts between row 11 and 15. Now, when I go into the print preview funtion and change the Zoom percentage to 150% or a custom 200%, I can see more or even all the rows that are missing as well as part of the header rows. The other reports that are using this web part all work fine. The report is also missing about half of a column of data. There is one of the other reports that is missing 1 and a half columns of data, but the the headers and all the data print.

Has anyone else seen an issue like this?

Also trying to set the selected value when the edit command is selected. here is the code below. In the update command i can find the control but for some reason the selected value is blank.
