Question

我一直试图在我的程序中添加一个功能，允许您使用OpenFileDialog选择文件（双击DataGridView单元格时）并将该单元格的值更改为文件的路径选择。我不知道命令是做什么的。我试图猜测，我在网上查了一下，找不到任何东西。

Private Sub dgSound_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgSound.CellDoubleClick

    If e.ColumnIndex = 3 Then 'Index of "file" column
        Dim file As String = ""
        OpenFileDialog1.ShowDialog()
        file = OpenFileDialog1.FileName

        'Contents of cell that was clicked = file          

    End If


End Sub

我使用CellClick而不是CellContentClick，如下所示......

  Private Sub dgSound_CellClick(sender As Object, e As DataGridViewCellEventArgs) Handles dgSound.CellClick
    If e.ColumnIndex = 3 Then 'Index of "file" column
      Dim file As String = ""
      OpenFileDialog1.ShowDialog()
      file = OpenFileDialog1.FileName

      'Contents of cell that was clicked = file          
      dgSound.Rows(e.RowIndex).Cells(e.ColumnIndex).Value = file

    End If

  End Sub

如何更改特定DataGridView单元格的值？
