I'm going through the articles in the DevNet section, and would like to know how to use the TNxCalcColumn column and the TNxGuidColumn column.
CODE
NextGrid1.Columns.Add(TNxCalcColumn,'My Calc');
//E2003 Undeclared identifier: 'TNxGuidColumn'
NextGrid1.Columns.Add(TNxGuidColumn,'My GUID');
//E2003 Undeclared identifier: 'TNxGuidColumn'
NextGrid1.Columns.Add(TNxGuidColumn,'My GUID');
Would someone have a small sample handy?
Thank you.
