從SqlDataSource設置會話變量

Question

我想從SqlDataSource的返回中設置一些會話變量。我能夠將值設置爲標籤/文本框/隱藏字段，但我似乎無法設置會話變量。

我正在使用page_load函數來嘗試設置它們。

protected void Page_Load(object sender, EventArgs e) 
{   
     this.Session["UserName"] = User.Identity.Name; 
     this.Session["EmplID"] = Eval("EmplID"); 
} 

我有一個SqlDataSource：

<asp:SqlDataSource ID="SQLGetEmplID" runat="server" 
      ConnectionString="<%$ ConnectionStrings:MAFapp %>" 
      SelectCommand="SELECT DISTINCT EmplID, Status FROM Employees WHERE (intLogin = @UserName) AND (Dept = N'Eng' OR Dept = N'IS') AND (Status = N'Active')"> 
    <SelectParameters> 
     <asp:SessionParameter Name="UserName" SessionField="UserName" /> 
    </SelectParameters> 
</asp:SqlDataSource>

你在做什麼，如果你User.Identity.Name

string fullUserName = null; 
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain)) 
{ 
    using (UserPrincipal user = UserPrincipal.FindByIdentity(pc,User.Identity.Name)) 
    { 
     if (user != null) 
     { 
      fullUserName = user.DisplayName;//this can be what ever you like 
     } 
    } 
}
