请问如何在DBGrid中添加ComboBox？

[jenniefang]

是一个用C＃编写的Windows应用程序，想在点击DBGrid的一个单元格时，其以ComboBox的形式供选择内容。之前有贴过一篇，用了RustemSoft DataGrid Columns library 的DataGrid Combobox column Style - .NET，但只是个演示版，不知有没其他方法或免费的控件，或已经破解的版本？
谢谢！

本实例利用Paint方法添加一个下拉框到DataGrid1上

1、新建一个Visual Basic Project 。
2、添加一个DataGrid control到窗体上。
3、加入以下代码



Imports System.Data.SqlClient



Public Class Form1

Inherits System.Windows.Forms.Form



#Region " Windows 窗体设计器生成的代码 "



Public Sub New()

MyBase.New()



'该调用是 Windows 窗体设计器所必需的。

InitializeComponent()



'在 InitializeComponent() 调用之后添加任何初始化



End Sub



'窗体重写处置以清理组件列表。

Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing Then

If Not (components Is Nothing) Then

components.Dispose()

End If

End If

MyBase.Dispose(disposing)

End Sub



'Windows 窗体设计器所必需的

Private components As System.ComponentModel.IContainer



'注意：以下过程是 Windows 窗体设计器所必需的

'可以使用 Windows 窗体设计器修改此过程。

'不要使用代码编辑器修改它。

Friend WithEvents DataGrid1 As System.Windows.Forms.DataGrid

<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()

Me.DataGrid1 = New System.Windows.Forms.DataGrid()

CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).BeginInit()

Me.SuspendLayout()

'

'DataGrid1

'

Me.DataGrid1.DataMember = ""

Me.DataGrid1.HeaderForeColor = System.Drawing.SystemColors.ControlText

Me.DataGrid1.Location = New System.Drawing.Point(72, 56)

Me.DataGrid1.Name = "DataGrid1"

Me.DataGrid1.Size = New System.Drawing.Size(416, 184)

Me.DataGrid1.TabIndex = 0

'

'Form1

'

Me.AutoScaleBaseSize = New System.Drawing.Size(6, 14)

Me.ClientSize = New System.Drawing.Size(552, 285)

Me.Controls.AddRange(New System.Windows.Forms.Control() {Me.DataGrid1})

Me.Name = "Form1"

Me.Text = "Form1"

CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).EndInit()

Me.ResumeLayout(False)



End Sub



#End Region





Public MyCombo As New ComboBox()

Dim con As New SqlConnection("server=lihg;uid=sa;pwd=sa;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





End Class

4、修连接字符串Dim con As New SqlConnection("server=lihg;uid=sa;pwd=sa;database=northwind")，使能连接上数据库
5、F5运行

有没C＃的版本啊？
