如何更改特定DataGridView单元的值？

Question

I've been trying to add a feature to my program that allows you to choose a file using OpenFileDialog (when you double click on a DataGridView cell) and change the value of that cell to the path of the file you chose. I have no idea what the command is to do that. I've tried to guess and I looked up on the internet and couldn't find anything.

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

I'd use CellClick rather than CellContentClick as follows...

  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
