Hi all,
I made a Master/detail page with 2 Radgrids (Persons and their Cars). When I start the page everything is ok. I get Persons and the Cars of the first person. After selecting the second row in the person grid (the row is clientside selectable and there is a postback with AJAX), I expect the cars of the second person, but I receive an error:
An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll
It is impossible for me to debug this error.
Ì am using ADO.NET entities. When a person is selected in the first grid, the id of the person is passed to the EntityDataSourceCar Datasource with a Control parameter in the Where parameters. The first time works because of the default values...
Has anybody a clue? Downhere is the code of the aspx. The aspx.cs is empty.
Thanks in advance,
Joost
