Concatenate Forename +姓氏SelectCommand

我試圖將TeacherForename + TeacherSurname的字段連接到我的下拉列表中，以便更清楚地向他們選擇的教師的用戶顯示。Concatenate Forename +姓氏SelectCommand

但是TeacherForename + TeacherSurname將保存TeacherID的值。

<div class="fields"> 
    <p> 
     <asp:Label ID="TeacherIdentification" runat="server" Font-Bold="True" 
      Width="150px">Teacher ID:</asp:Label> 
     <asp:DropDownList ID="DropDownList2" runat="server" 
      DataSourceID="SqlDataSource2" DataTextField="TeacherForename" 
      DataValueField="TeacherID" Height="29px" Width="155px" 
      CssClass="Dropdownlist"> 
     </asp:DropDownList> 
     <asp:SqlDataSource ID="SqlDataSource2" runat="server" 
      ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
      ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" 
      SelectCommand="SELECT Class.TeacherID, Teacher.TeacherForename, Teacher.TeacherSurname FROM (Class INNER JOIN Teacher ON Class.TeacherID = Teacher.TeacherID)"> 
     </asp:SqlDataSource> 
    </p> 
</div>

我試圖做這自己，但我不能選擇命令權，它在我的下拉列表中不會顯示，任何人都可以點我在正確的方向？

我想補充AS子句...的SelectCommand = 「SELECT Class.TeacherID，（Teacher.TeacherForename +」「+ Teacher.TeacherSurname）作爲TeacherFullName FROM（類INNER JOIN教師ON Class.TeacherID =教師。 TeacherID）「並在您的數據源中更改DataTextField =」TeacherFullName「 – Mych

謝謝！但顯然服務器標籤是不正確的，我看不到任何錯誤... – Callum

感謝您的升級，現在我將更新並檢查它 – jainvikram444
