Telerik RadGrid Throwing an exception when filling an array of objects by their parent type

Question

I just encountered a casting exception when using Telerik RadGrid.

This happens during the DataBind event if I have an array of objects as a data source

radgrid1.DataSource = new BaseObject[] { new ChildObject1(), new ChildObject2() };

where the ChildObject1 and ChildObject2 classes inherit from the BaseObject class.

Just found the answer.

var objects = new BaseObject[] { new ChildObject1(), new ChildObject2() };

radgrid1.DataSource = new List<BaseObject>(objects);
