vb6 - MSFlexGrid 编辑 VB6

Question

目前我正在开发 vb6 应用程序。我想在 MSFlexgrid 中显示数据但是 MSFlexgrid 控件中没有编辑工具。

有没有办法编辑 MSFlexgrid？

Answer 1

有一种使用隐藏文本框的方法。在单元格上双击文本框将可见并且可以编辑这里是代码片段检查它

Private Sub Form_Load()

   'Setting Col And row

    MSFlexGrid1.Cols = 3
    MSFlexGrid1.Rows = 10
    'First row
    MSFlexGrid1.TextMatrix(0, 0) = "ID"
    MSFlexGrid1.TextMatrix(0, 1) = "Date"
    MSFlexGrid1.TextMatrix(0, 2) = "Voucher Type"
    'some data
    MSFlexGrid1.TextMatrix(1, 0) = "E0000001"
    MSFlexGrid1.TextMatrix(2, 0) = "E0000001"
    MSFlexGrid1.TextMatrix(1, 1) = "01/04/10"
    MSFlexGrid1.TextMatrix(2, 1) = "01/04/10"    
    MSFlexGrid1.TextMatrix(1, 2) = "Jrnl"
    MSFlexGrid1.TextMatrix(2, 2) = "Jrnl"
End Sub

Private Sub MSFlexGrid1_DblClick()

    'If MSFlexGrid1.Col = 3 Or MSFlexGrid1.Col = 6 Or MSFlexGrid1.Col = 7 Then
        GridEdit Asc(" ")
    'End If
End Sub

Private Sub MSFlexGrid1_KeyPress(KeyAscii As Integer)

        GridEdit KeyAscii

End Sub

Sub GridEdit(KeyAscii As Integer)

  'use correct font  
  Text1.FontName = MSFlexGrid1.FontName
  Text1.FontSize = MSFlexGrid1.FontSize

  Select Case KeyAscii

     Case 0 To Asc(" ")
        Text1 = MSFlexGrid1
        Text1.text = Trim(Text1.text)
        Text1.SelStart = 1000

     Case Else
         Text1 = MSFlexGrid1
         Text1.text = Trim(Text1.text)
        Text1.SelStart = 1000

 End Select

  'position the edit box


  Text1.Left = MSFlexGrid1.CellLeft + MSFlexGrid1.Left

  Text1.Top = MSFlexGrid1.CellTop + MSFlexGrid1.Top

  Text1.Width = MSFlexGrid1.CellWidth

  Text1.Height = MSFlexGrid1.CellHeight

  Text1.Visible = True

  Text1.SetFocus

End Sub

Private Sub MSFlexGrid1_LeaveCell()

  If Text1.Visible Then

    If MSFlexGrid1.Col = 6 Or MSFlexGrid1.Col = 7 Then
        If Text1.text = "" Then
            Text1.text = " "
        End If
    End If
     MSFlexGrid1 = Text1
     Text1.Visible = False

  End If

End Sub

Private Sub MSFlexGrid1_GotFocus()

  If Text1.Visible Then

    If MSFlexGrid1.Col = 6 Or MSFlexGrid1.Col = 7 Then

        If Text1.text = "" Then
            Text1.text = " "
        End If

    End If

     MSFlexGrid1 = Text1.text
     Text1.Visible = False

  End If

End Sub

Private Sub Text1_KeyPress(KeyAscii As Integer)

  'noise suppression

  If MSFlexGrid1.Col <> 6 And MSFlexGrid1.Col <> 7 Then

    KeyAscii = 0

  End If

  If KeyAscii = vbKeyReturn Then

    KeyAscii = 0

  End If

End Sub

你也可以试试下面的代码。这不需要文本框。

'Put this code in MSFlexGrid Keypress Event

'===================================================
Private Sub MSFlexGrid_KeyPress(KeyAscii As Integer)
With MSFlexGrid
    Select Case KeyAscii

        Case 8: 'IF KEY IS BACKSPACE THEN
            If .Text <> "" Then .Text = _
             Left$(.Text, (Len(.Text) - 1))
        Case 13: 'IF KEY IS ENTER THEN
            Select Case .Col
                Case Is < (.Cols - 1):
                    SendKeys "{right}"
                Case (.Cols - 1):
                    If (.Row + 1) = .Rows Then
                        .Rows = .Rows + 1
                    End If
                    SendKeys "{home}" + "{down}"
            End Select
        Case Else
            .Text = .Text + Chr$(KeyAscii)
            'write your own keyascii Validations under 
                   'commented lines
            Select Case .Col
                Case 0, 1, 2:
                    'if (your condition(s)) then
                        'accept only charectors
                    'Else
                    '   keyascii=0
                    'End If
                Case Else:
            End Select
    End Select
End With


End Sub
