如何使用VB.Net在datagridview的特定列中设置单元格格式？

Question

我正在使用DatagridView工具。在这里，我正在对列进行手动输入并将其直接保存到数据库中。我有5个列，其中3个是字母数字，2个是数字列。

我已经将条件设置为在EditingControlShowing事件中使用处理程序的数字列。

If grdLedgerDetails.CurrentCell.ColumnIndex = 4 Then 
     AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress 
    ElseIf grdLedgerDetails.CurrentCell.ColumnIndex = 5 Then 
     AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress 
    End If 


Private Sub TextBox_keyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) 
    If Char.IsDigit(CChar(CStr(e.KeyChar))) = False Then e.Handled = True 
End Sub 

此条件适用。但问题是，这种情况适用于所有列。我只是想让它在指定的列上工作。

请帮我解决这个问题。

在此先感谢。

这工作得很好。

Private Sub grdLedgerDetails_EditingControlShowing(sender As Object, e As     System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles grdLedgerDetails.EditingControlShowing 
    Select grdLedgerDetails.CurrentCell.ColumnIndex 
     Case 2, 3 
      RemoveHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress 
     Case 4, 5 
      AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress 
    End Select 
End Sub 



Private Sub TextBox_keyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) 
    If Not Char.IsControl(e.KeyChar) And Not Char.IsDigit(e.KeyChar) And e.KeyChar <> "." Then 
     e.Handled = True 
    End If 
     End Sub

尝试这样

Private Sub dgv_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) 
    RemoveHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress 
    AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress 
End Sub 

Private Sub TextBox_keyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) 
    Select Case grdLedgerDetails.CurrentCell.ColumnIndex 
     Case 4,5 
      If Char.IsDigit(CChar(CStr(e.KeyChar))) = False Then e.Handled = True 
    End Select 
End Sub
