dropdownlist赋值问题
<asp:DropDownList ID="depNo" runat="server" Width="160px" AutoPostBack="True" />
要怎么把MSSQL的值塞进depNo这个控件里?

SQL查询命令:
Dim mySQL As String = "SELECT DepartmentNo, DepartmentName FROM tblMstDepartment Where DepartmentNo Like '72%' And DeptLevelNo In (50, 80) Order By DepartmentNo"

自己找出来了...

程序代码:
Private Sub GetDepNo()
        Dim dbCmdSQL As SqlCommand
        Dim mySQL As String = "SELECT DepartmentNo, DepartmentName FROM tblMstDepartment Where DepartmentNo Like '72%' And DeptLevelNo In (50, 80) Order By DepartmentNo"
        depNo.Items.Clear()
        depNo.Items.Add(New ListItem(""))
        Try
            Using mySqlDS = New SqlConnection(ConfigurationManager.ConnectionStrings(strCnnType & "DbBTA").ToString)
                dbCmdSQL = New SqlCommand(mySQL, mySqlDS)
                mySqlDS.Open()
                Using dbDRSQL = dbCmdSQL.ExecuteReader
                    While dbDRSQL.Read
                        Dim str As String = dbDRSQL("DepartmentNo").ToString & " " & dbDRSQL("DepartmentName").ToString
                        depNo.Items.Add(New ListItem(str))
                    End While
                End Using
            End Using
        Catch ex As Exception
            Dim strErr As String = "●●● 程式错误讯息如下 ●●●" & "\n\n" & Replace(Replace(Replace(Replace(Trim(ex.ToString()), Chr(10), ""), Chr(13), ""), "\", "\\"), "'", "\'")
            ScriptManager.RegisterStartupScript(Me, Me.GetType(), "alert", "alert('" & strErr & "');", True)
        End Try
    End Sub

连动也OK了...

程序代码:
Protected Sub depNo_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles depNo.SelectedIndexChanged
        Dim DepNo As String = sender.SelectedValue : DepNo = Mid(DepNo, 1, 4)
        Dim dbCmdSQL As SqlCommand
        Dim mySQL As String
        UserNo.Items.Clear() : UserNo.Items.Add(New ListItem(""))
        ClassNo.Items.Clear() : ClassNo.Items.Add(New ListItem(""))
        Try
            mySQL = "SELECT EmployeeNo, EmployeeName FROM tblMstEmployee Where DepartmentNo = '" & DepNo & "' AND Active = 'Y'"
            Using mySqlDS = New SqlConnection(ConfigurationManager.ConnectionStrings(strCnnType & "DbBTA").ToString)
                dbCmdSQL = New SqlCommand(mySQL, mySqlDS)
                mySqlDS.Open()
                Using dbDRSQL = dbCmdSQL.ExecuteReader
                    While dbDRSQL.Read
                        Dim str As String = dbDRSQL("EmployeeName").ToString & " (" & dbDRSQL("EmployeeNo").ToString & ")"
                        UserNo.Items.Add(New ListItem(str))
                    End While
                End Using
            End Using

            mySQL = "SELECT ClassID, SubClassID, FileID FROM tblClassList"
            Using mySqlDS = New SqlConnection(ConfigurationManager.ConnectionStrings(strCnnType & "DbBTA").ToString)
                dbCmdSQL = New SqlCommand(mySQL, mySqlDS)
                mySqlDS.Open()
                Using dbDRSQL = dbCmdSQL.ExecuteReader
                    While dbDRSQL.Read
                        Dim str As String = GetClassName(0, dbDRSQL("ClassID").ToString, dbDRSQL("SubClassID").ToString, dbDRSQL("FileID").ToString)
                        ClassNo.Items.Add(New ListItem(str))
                    End While
                End Using
            End Using
        Catch ex As Exception
            Dim strErr As String = "●●● 程式错误讯息如下 ●●●" & "\n\n" & Replace(Replace(Replace(Replace(Trim(ex.ToString()), Chr(10), ""), Chr(13), ""), "\", "\\"), "'", "\'")
            ScriptManager.RegisterStartupScript(Me, Me.GetType(), "alert", "alert('" & strErr & "');", True)
        End Try
    End Sub
