Subclasses that override the GetCell method should override this method as well
protected override Foundation.NSString CellKey { get; }
member this.CellKey : Foundation.NSString
Unique NSString value, typically the underlying value is allocated as a static variable.
This method should return the key passed to UITableView.DequeueReusableCell. If your code overrides the GetCell(UITableView) method to change the cell, you must also override this method and return a unique key for it. This works in most subclasses with a couple of exceptions: StringElement and various derived classes do not use this setting as they need a wider range of keys for different uses, so you need to look at the source code for those if you are trying to override StringElement or StyledStringElement.
