创建一个带标题的DataGridView（嵌入到GroupBox中）

Question

I have a DataGridView and I want to put it into a GroupBox. In VB6 it looked like this:

So it is just a MsFlexGrid wrapped by a GroupBox. I've absolutely no idea, how to implement that in VB.NET.

I'd let it inherit from DataGridView, so it is a Control, and it has every Property of the DataGridView by default.

Public Class CaptionedDataGridView
    Inherits DataGridView

There would also have to be a GroupBox:

Private xGroupBox as GroupBox

The text property would be overrided by the text of the group box as well as some size and placement properties (Top, Left, Width, Height)

Public Overrides Property Text As String
  Get
    Return xGroupBox.Text
  End Get
  Set(ByVal value As Integer)
    xGroupBox.Text = value
  End Set
End Property

Finally, if I'd create a new CaptionedDataGridView somewhere it should draw itself with the GroupBox sorrounded. How do I get from where I am right now to where I want to be?

Answer 1

I think you have to do that the other way around. Inherit from the GroupBox and add the DataGridView to it.

Simple example:

Public Class MyGrid
  Inherits GroupBox

  Private _Grid As DataGridView

  Public Sub New()
    _Grid = New DataGridView()
    _Grid.Dock = DockStyle.Fill
    Me.Controls.Add(_Grid)
  End Sub

  ReadOnly Property Grid As DataGridView
    Get
      Return _Grid
    End Get
  End Property

End Class

Of course, you don't have to do this as a custom control. You can just put a GroupBox on your form and add the DataGridView to it with that same DockStyle.Fill property.
