在數據庫中發送用戶名

我有一個詳細信息視圖，在其中啓用了「編輯/新建」。在「新的」，以及將在數據庫行中的其他額外信息，即時通訊也試圖發送當前用戶名登錄。目前，它保持爲空。在數據庫中發送用戶名

這裏是我的代碼：

<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>

使用一個會話變量的用戶名在後面的代碼存儲這樣

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>

如何修改我的查詢根據會話變量？我的意思是，我將它存儲在變量中後，如何將其發送回數據庫？ –

從後面的代碼中添加插入參數，就像這個'AccessDataSource2.InsertParameters.Add（「User Name」，Session（「User」））' – scc

或者你可以在插入參數中使用'SessionParameter'而不是'Parameter'用戶名這將是最簡單的方法 – scc

試試這個

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

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

    End Sub
