How do I use GetColumnName function of GGC in QTP?

To make use of the GetColumnName, the table name and column index are needed. The table name can be known from GetTableName or GetTableNameByLevel. In GetTableName function, the row index (i.e., the display element index) is passed; for GetTableNameByLevel, only the hierarchy level is passed. The sample script below retrieves the fourth column name of the first child table.

SwfWindow("GridGroupingControl").SwfObject("gridGroupingControl1").SetCurrentCell 5,"parentID"

SwfWindow("GridGroupingControl").SwfObject("gridGroupingControl1").ExpandRecord 5

tablename = SwfWindow("GridGroupingControl").SwfObject("gridGroupingControl1").GetTableName(10)

'tablename = SwfWindow("GridGroupingControl").SwfObject("gridGroupingControl1").GetTableNameByLevel(1)

colIndex = 5 ' just the 4th column but including the +/- button as 1st column, this is 5th column

colname = SwfWindow("GridGroupingControl").SwfObject("gridGroupingControl1").GetColumnName(tablename, colIndex)

MsgBox "The name of the column in thechild table is " & colname
