我有一个详细信息视图，其中启用了“编辑/新建”。在“新”上，连同将进入数据库行的其他额外信息，我也在尝试发送当前登录的用户名。目前，它保持为空。

这是我的代码：

<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="700px" 
        AutoGenerateRows="False" DataKeyNames="ID" 
        DataSourceID="AccessDataSource2" AllowPaging="True" CssClass="mdtlstblwithhlines">
        <Fields>
            <asp:TemplateField HeaderText="Rating" SortExpression="Rating">
                <EditItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Rating") %>'></asp:TextBox>
                </EditItemTemplate>
                <InsertItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Rating") %>'></asp:TextBox>
                </InsertItemTemplate>
                <ItemTemplate>
                 <asp:Rating ID="Rating1" CurrentRating= '<%# Bind("Rating") %>'
                        runat="server" EmptyStarCssClass="EmptyStar" 
                        FilledStarCssClass="FilledStar" StarCssClass="Star" 
                        WaitingStarCssClass="WaitingStar" AutoPostBack="True" Enabled="True" 
                        EnableTheming="True" ReadOnly="True">
                    </asp:Rating>

                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField="TheGood" HeaderText="TheGood" 
                SortExpression="TheGood" />
            <asp:BoundField DataField="TheBad" HeaderText="TheBad"

尝试这个

  Public Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs )

        SqlDataSource1.InsertParameters("UserName").DefaultValue = User.Identity.Name

  End Sub

使用会话变量将用户名存储在后面的代码中，如下所示

Dim crntuser As String = ""
crntuser = Login1.UserName.ToString
Session.Add("User", crntuser)


<InsertParameters>
    <asp:Parameter Name="ItemID" Type="Int32" />
    <asp:Parameter Name="UserID" Type="String" />
    <asp:SessionParameter Name="UserName" SessionField="User" Type="String" />
    <asp:Parameter Name="Rating" Type="Int32" />
    <asp:Parameter Name="TheGood" Type="String" />
    <asp:Parameter Name="TheBad" Type="String" />
    <asp:Parameter Name="TheBottomLine" Type="String" />
    <asp:Parameter Name="DatePosted" Type="DateTime" />
    <asp:Parameter Name="LastUpdate" Type="DateTime" />
</InsertParameters>
