For complex data binding, the Type of the items represented by the dataMember in the data source; otherwise, the Type of the item in the list itself.
Remarks
This version of the GetListItemType method is used to determine the type of items used in complex or simple data-binding schemes. This static method may be useful in determining whether a proposed data-binding scheme is appropriate before attempting it.
If dataSource is null, the property descriptors cannot be found for the list items of the specified data member, or the property descriptor for the list item is an ICustomTypeDescriptor, then this method returns the type of the Object class.
If dataMember is null or empty, then this method returns the Type of the items in the data source, if it is a list; otherwise, this method returns the Type of the data source itself.
