Um Bem Aja

Existe maneira de apresentar num Datagridview do Vb Net 2013 o efeito de Mergecells como no VB6 via Mshflexgrid ?

Oi Ribeiro

Aproveitando a tua resposta e no seguimento do topico andei a vasculhar pela net e encontrei esta classe.

Mas não sei se serve e não sei como aplicar no meu projecto

//
Public Class GroupByGrid
   Inherits DataGridView
   Protected Overrides Sub OnCellFormatting(ByVal args As DataGridViewCellFormattingEventArgs)
    MyBase.OnCellFormatting(args)
    ' First row always displays
    If args.RowIndex = 0 Then
	    Return
    End If
    If IsRepeatedCellValue(args.RowIndex, args.ColumnIndex) Then
	    args.Value = String.Empty
	    args.FormattingApplied = True
    End If
   End Sub
   Private Function IsRepeatedCellValue(ByVal rowIndex As Integer, ByVal colIndex As Integer) As Boolean
    Dim currCell As DataGridViewCell = Rows(rowIndex).Cells(colIndex)
    Dim prevCell As DataGridViewCell = Rows(rowIndex - 1).Cells(colIndex)
    If (currCell.Value Is prevCell.Value) OrElse (currCell.Value IsNot Nothing AndAlso prevCell.Value IsNot Nothing AndAlso currCell.Value.ToString() = prevCell.Value.ToString()) Then
	    Return True
    Else
	    Return False
    End If
   End Function
   Protected Overrides Sub OnCellPainting(ByVal args As DataGridViewCellPaintingEventArgs)
    MyBase.OnCellPainting(args)
    args.AdvancedBorderStyle.Bottom = DataGridViewAdvancedCellBorderStyle.None
    ' Ignore column and row headers and first row
    If args.RowIndex < 1 OrElse args.ColumnIndex < 0 Then
	    Return
    End If
    If IsRepeatedCellValue(args.RowIndex, args.ColumnIndex) Then
	    args.AdvancedBorderStyle.Top = DataGridViewAdvancedCellBorderStyle.None
    Else
	    args.AdvancedBorderStyle.Top = AdvancedCellBorderStyle.Top
    End If
   End Sub

   Private Sub InitializeComponent()
    CType(Me, System.ComponentModel.ISupportInitialize).BeginInit()
    Me.SuspendLayout()
    CType(Me, System.ComponentModel.ISupportInitialize).EndInit()
    Me.ResumeLayout(False)
   End Sub
End Class

tenho um este form com uma datagridview que vai buscar os dadoa a uma tabela access

//
Public Class frmRoscasTabelaComposta

   Private Sub frmRoscasTabelaComposta_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    'TODO: This line of code loads data into the 'RoscasDataSet.TabRoscas' table. You can move, or remove it, as needed.
    Me.TabRoscasTableAdapter.Fill(Me.RoscasDataSet.TabRoscas)
   End Sub
   Private Sub btnSair_Click(sender As Object, e As EventArgs) Handles btnSair.Click
    Me.Close()
   End Sub
End Class
