Solution 1: Use the SAP GUI scripting recorder
Start the script recording via the SAP GUI options:

Then change the width of each column for which you want to find out the name. Stop the recording and display the generated .vbs file; it will contain the internal column names. Example:

session.findById("wnd[0]/usr/cntlGRID1/shellcont/shell").setColumnWidth "AUFNR",14
session.findById("wnd[0]/usr/cntlGRID1/shellcont/shell").setColumnWidth "AUART",6
session.findById("wnd[0]/usr/cntlGRID1/shellcont/shell").setColumnWidth "GSTRP",11
session.findById("wnd[0]/usr/cntlGRID1/shellcont/shell").setColumnWidth "KTEXT",43 

The column names in this example are AUFNR, AUART,GSTRP, KTEXT.

Solution 2: Use a SAP GUI trace
Switch on the "GridView control" trace in the SAP GUI options:

Then start the transaction so that the grid is displayed. Switch off the trace and display the trace file. It will contain lines of the following kind:

...
<41=GridView Control : SetInfoTable: ColumnOutputLength(pInfoTableLineStretched->m_nOutputLength)=2
<41=GridView Control : F=1, T=1, nwidth=21
<41=GridView Control : SetInfoTable: ColumnNo=2
<41=GridView Control : SetInfoTable: ColumnID=AUFNR
<41=GridView Control : SetInfoTable: ColumnText=Order
<41=GridView Control : SetInfoTable: ColumnOutputLength(pInfoTableLineStretched->m_nOutputLength)=12
<41=GridView Control : F=2, T=2, nwidth=91
<41=GridView Control : SetInfoTable: ColumnNo=3
<41=GridView Control : SetInfoTable: ColumnID=AUART
<41=GridView Control : SetInfoTable: ColumnText=Order Type
<41=GridView Control : SetInfoTable: ColumnOutputLength(pInfoTableLineStretched->m_nOutputLength)=4
...

Here you see the internal column names and the corresponding column titles.


Solution 3: Use the GuiXT "Native control Interface"

The "Native conrol interface" is available in GuiXT Controls version 2019 Q1 1 and above. You can use it to write a small helper function that returns the column names and titles.

Add the following Visual Basic function in one of your VB.NET dlls in a suitable class, e.g. dll "utilities.dll" and class "grid":

  ' return internal column names
    Public Function DevHelpColumnNames() As String

        Dim gridview As GridView = guixt.getcontrol("grid")

        If gridview Is Nothing Then
            Return "Grid not found"
        End If

        Dim msg As String = ""

        For k As Integer = 1 To gridview.GetColCount()
            msg &= "// " & gridview.GetColIDFromPos(k) & vbTab _
                    & OCXUTF8(gridview.GetColText(k)) & vbCrLf
        Next

        Return msg

    End Function

    Private Function OCXUTF8(str As String) As String
        Return System.Text.Encoding.UTF8.GetChars  _
                  (System.Text.Encoding.Default.GetBytes(str))
    End Function

Add a GuiXT button in the SAP grid screen which calls up the "DevHelpColumnNames" function via an InputScript:


GuiXT script

pushbutton (toolbar) "Show column names" process="show_column_names.txt"


 




The InputScript (see below) will also insert the column names into the Windows clipboard so that you can paste the names into your script or VB program:






InputScript

/ Development only: show internal column names
CallVB column_names = utilities.grid.DevHelpColumnNames
Message "&V[column_names]" title="Column names Insert via Ctrl+V"

// copy to Windows clipboard for script insertion
Set text[column_names] "&V[column_names]"
CopyText fromText="column_names" -toClipboard

Return
