这文章我也找到了,不过
Public Delegate Sub DataGridCellButtonClickEventHandler(ByVal sender As Object, ByVal e As DataGridCellButtonClickEventArgs)

这句在我机器上报错,提示没有定义,郁闷,调不过去

提示DataGridCellButtonClickEventArgs 没有定义

Public MyCombo As New ComboBox()
Dim con As New SqlConnection("server=myservername;uid=myid;pwd=mypassword;database=northwind")
Dim daEmp As New SqlDataAdapter("Select * From Employees", con)

Public ds As New DataSet()
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AddHandler MyCombo.TextChanged, AddressOf Ctrls_TextChanged
'Fill ComboBox list.
MyCombo.Name = "MyCombo"
MyCombo.Visible = False
MyCombo.Items.Clear()
MyCombo.Items.Add("Sales Representative")
MyCombo.Items.Add("Inside Sales Coordinator")
MyCombo.Items.Add("Vice President, Sales")
MyCombo.Items.Add("Sales Manager")
MyCombo.Items.Add("Flunky")


daEmp.Fill(ds, "Employees")

'Set the RowHeight of the DataGrid to the height of the ComboBox.
DataGrid1.PreferredRowHeight = MyCombo.Height

DataGrid1.DataSource = ds

DataGrid1.DataMember = "Employees"
'Add ComboBox to the Control collection of the DataGrid.
DataGrid1.Controls.Add(MyCombo)
End Sub

Private Sub DataGrid1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles DataGrid1.Paint
If DataGrid1.CurrentCell.ColumnNumber = 3 Then
MyCombo.Width = DataGrid1.GetCurrentCellBounds.Width
End If
End Sub

Private Sub Ctrls_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)
If DataGrid1.CurrentCell.ColumnNumber = 3 Then
MyCombo.Visible = False
If DataGrid1.Item(DataGrid1.CurrentCell) & "" = "" Then
SendKeys.Send("*")
End If
DataGrid1.Item(DataGrid1.CurrentCell) = MyCombo.Text
End If
End Sub

Private Sub DataGrid1_CurrentCellChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.CurrentCellChanged
If DataGrid1.CurrentCell.ColumnNumber = 3 Then
MyCombo.Visible = False
MyCombo.Width = 0
MyCombo.Left = DataGrid1.GetCurrentCellBounds.Left
MyCombo.Top = DataGrid1.GetCurrentCellBounds.Top
MyCombo.Text = DataGrid1.Item(DataGrid1.CurrentCell) & ""
MyCombo.Visible = True
Else
MyCombo.Visible = False
MyCombo.Width = 0
End If
End Sub

Private Sub DataGrid1_Scroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.Scroll
MyCombo.Visible = False
MyCombo.Width = 0
End Sub

Private Sub DataGrid1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.Click
MyCombo.Visible = False
MyCombo.Width = 0
End Sub
原理是一样的
