Larry,
Where do the docs state that? That would be totally incorrect.

The MemberClass/MemberCLassLibrary properties of the Grid specify the Column class to use. The HeaderClass/HeaderClassLibrary properties of the Column class specify what header to instantiate in the Column container.

HTH.

>I am having trouble instantiating a non-visual custom column class. The docs say to use the HeaderClass (and not the grid's MemberClass) property for custom columns but does show an example. (I don't understand why you wouldn't use the grid's Memberclass, since the only child members in a grid are columns) Can someone pls show me an example?
