推荐答案

您可以为组合框定义ItemsSource。



这是一个例子 http://blogs.msdn.com/b/vinsibal/archive/2008/10/31/wpf-datagrid-datagridcomboboxcolumn-v1-intro.aspx [ ^ ]

You define the ItemsSource for the combo box.

Here's one example http://blogs.msdn.com/b/vinsibal/archive/2008/10/31/wpf-datagrid-datagridcomboboxcolumn-v1-intro.aspx[^]

公共属性Warehouse（）As ObservableCollection（Of String）

函数loadWarehouse（）

Dim a As String

Dim dbConn As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection（ConfigurationManager.AppSettings（ConnectionString））

Dim ConString As String = ConfigurationManager.ConnectionStrings（CompuTrakwpf.MySettings.CompuTrakDBConnectionString）。ConnectionString

dbConn.ConnectionString = ConString：dbConn.Open（）

Dim DS et As New DataSet，SQLStr As String

Dim cmd As System.Data.SqlClient.SqlCommand

Dim dbAdaptr As System.Data.SqlClient.SqlDataAdapter = New System.Data。 SqlClient.SqlDataAdapter

Dim tRow As DataRow，tTbl As DataTable

尝试

使用dbAdaptr

.TableMappings.Add （表，仓库）

SQLStr =按[仓库]顺序从[仓库]中选择[仓库]

cmd =新的System.Data.SqlClient .SqlCommand（SQLStr，dbConn）

cmd.CommandType = CommandType.Text

.SelectCommand = cmd

.Fill（DSet）

.Dispose（）

结束

DSet.AcceptChanges（）

tTbl = DSet.Tables.Item（0）

DSet.Dispose（）：dbConn.Close（）

仓库=新的ObservableCo llection（Of String）（）来自{}

每个tRow in tTbl.Rows

a =（tRow（仓库）。ToString）

Warehouse.Add（a）

下一页

返回0

Catch ex As Exception

MsgBox （错误描述）

结束尝试

结束功能

Public Property Warehouse() As ObservableCollection(Of String)
Function loadWarehouse()
Dim a As String
Dim dbConn As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(ConfigurationManager.AppSettings("ConnectionString"))

For Each tRow In tTbl.Rows

Next
Return 0
