我是一名新的ASP.NET开发人员,并尝试使用GridView控件显示数据库中employee表中的所有员工.我现在正在努力更新GridView中的信息.我面临以下问题,我不知道为什么:

**

除非指定了UpdateCommand,否则数据源'SqlDataSource1'不支持更新.

**

仅供参考,我有以下数据库设计:

Employee Table: Username, Name, JobTitle, BadgeNo, IsActive, DivisionCode
Divisions Table: SapCode, DivisionShortcut

(IsActive就像一个标志(位数据类型)来指示员工是否在某个任务中)

ASP.NET代码:

<asp:GridView ID="GridView1" runat="server" AllowSorting="True" 
            AutoGenerateColumns="False" DataKeyNames="Username" 
            DataSourceID="SqlDataSource1" BorderWidth="1px" BackColor="#DEBA84" 
             CellPadding="3" CellSpacing="2" BorderStyle="None" 
             BorderColor="#DEBA84" OnRowEditing="GridView1_RowEditing" 
             OnRowCancelingEdit="GridView1_RowCancelingEdit" 
             OnRowUpdating="GridView1_RowUpdating">
            <FooterStyle ForeColor="#8C4510" 
              BackColor="#F7DFB5"></FooterStyle>
            <PagerStyle ForeColor="#8C4510" 
              HorizontalAlign="Center"></PagerStyle>
            <HeaderStyle ForeColor="White" Font-Bold="True" 
              BackColor="#A55129"></HeaderStyle>
            <Columns>
                <asp:CommandField ButtonType="Button" ShowEditButton="true" ShowCancelButton="true" />

                <asp:TemplateField>
                    <ItemTemplate>
                        <%# Eval("DivisionShortcut")%>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:DropDownList ID="DivisionsList" runat="server" DataSourceID="DivisionsListDataSource"
                                            DataTextField="DivisionShortcut" DataValueField="SapCode"></asp:DropDownList>
                    </EditItemTemplate>
                </asp:TemplateField>

                <asp:BoundField DataField="Username" HeaderText="Network ID" ReadOnly="True" 
                    SortExpression="Username" />

                <asp:TemplateField>
                    <ItemTemplate>
                        <%# Eval("Name")%>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox ID="txtEmployeeName" …
