  I migrate a Windows app from VB6 to VBNET.
  
  I use C1.Win.C1FlexGrid.Classic to design grid.
  
  But I can not merge 2 header columns with the set_MergeCol function

  With flexrKTList
  
              .Clear(ClearWhereSettings.flexClearEverywhere, ClearWhatSettings.flexClearEverything)
              .Cols = 16
              .Rows = 2
  
              .MergeCells = MergeSettings.flexMergeFixedOnly
              .set_MergeCol(0, True)
              .set_MergeCol(1, True)
              .set_MergeRow(0, True)
  
              .set_TextMatrix(0, 0, "開始工程")
              .set_TextMatrix(1, 0, "開始工程")
              For intCnt = 1 To 7
                  .set_TextMatrix(0, intCnt * 2 - 1, Format(DateAdd(Microsoft.VisualBasic.DateInterval.Day, -1 * (7 - intCnt), mdteBaseDay), "M/d(ddd)"))
                  .set_TextMatrix(0, intCnt * 2, .get_TextMatrix(0, intCnt * 2 - 1))
                  .set_TextMatrix(1, intCnt * 2 - 1, "件数")
                  .set_TextMatrix(1, intCnt * 2, "数量")
                  .set_ColWidth(intCnt * 2 - 1, TwipsToPixels(700))
                  .set_ColWidth(intCnt * 2, TwipsToPixels(900))
              Next intCnt
  
              ''.let_Cell(VSFlex7L.CellPropertySettings.flexcpBackColor, 0, 13, 1, 15, &HFFC0C0)
  
              .set_ColWidth(0, TwipsToPixels(3200))
              .set_ColWidth(15, TwipsToPixels(0))
  
              .set_FixedAlignment(-1, AlignmentSettings.flexAlignCenterCenter)
              .set_ColAlignment(-1, AlignmentSettings.flexAlignRightCenter)
              .set_ColAlignment(0, AlignmentSettings.flexAlignLeftCenter)
  
              .set_RowHeight(-1, TwipsToPixels(400))
          End With

  Hello,
  
  Apologies for the delayed response.
  
  C1FlexGridClassic is a wrapper class for C1FlexGrid, designed to facilitate a seamless transition from VSFlexGrid to C1FlexGrid.
  
  You can merge Fixed Columns in C1FlexGridClassic by setting the MergeCells property to MergeSettings.flexMergeFixedOnly and setting the AllowMerge property of each Column to True as follows:

  C1FlexGridClassic1.MergeCells = C1.Win.C1FlexGrid.Classic.MergeSettings.flexMergeFixedOnly
  
  For Each col As C1.Win.C1FlexGrid.Column In C1FlexGridClassic1.ColumnCollection
      col.AllowMerging = True
  Next

  Please refer to the attached sample for implementation. (see FlexGridClassic48_MergeHeaders_VB.zip)
  
  Regards,
  
  Uttkarsh.
