I have a radgrid that binds an object stored in the ViewState (Case). When I click on the radgrid's "Add" button (firing the OnInsertCommand) I get the following error: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'LookupValue'.' The specific control I am having problems with is the RadDropDownTree, and only when its definition contains this "SelectedValue='<%# Bind("LookupValue.Code") %>'"
I do not understand why this is happening. What is so different now that my radgrid is binding to a object that contains a subobject?? What do I need to be doing differently?
Just as an fyi, I do not get this error when the OnUpdateCommand fires. Below is my code.
