I am facing a problem with the updatepanel.
I am using a ASP menu control. I have a lable control within an UpdatePanel.
Upon clicking the menu , I pick the selectedvalue and display as lable text. My code works but whenever I click I get the previously selected value in the lable and not the latest one.

For ex:I have Item1,Item2,Item3 and Item4 in my menu

Upon loading I click Item1 the lable does not refresh.
Then I click on Item3 this time the lable refreshes but shows the previously selected value i.e:Item1.
Then I click on Item2 this time the lable refreshes but again shows the previously selected value i.e:Item3.:mad: X|

Below is my aspx code

                <asp:MenuItem Text="Item1" Value="Item1"></asp:MenuItem>
                <asp:MenuItem Text="Item2" Value="Item2"></asp:MenuItem>
                <asp:MenuItem Text="Item3" Value="Item3"></asp:MenuItem>
                <asp:MenuItem Text="Item4" Value="Item4"></asp:MenuItem>
            </Items>
        </asp:Menu>
        
         <asp:ScriptManager ID="ScriptManager1" 
                   runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" 
                 UpdateMode="Conditional"
                 runat="server">
                 <Triggers>
                   <asp:AsyncPostBackTrigger ControlID="Menu1" />
                 </Triggers>
                 <ContentTemplate>
                 <fieldset>
                 <asp:Label ID="Label1" runat="server" 
                            ForeColor="White" Font-Size="Large" BackColor="#00447b" Width="700px" ></asp:Label>
                 </fieldset>
                 </ContentTemplate>
</asp:UpdatePanel>
    
    </div>
    </form>
</body>
</html>

this is my code behind

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Menu1.SelectedItem != null)
            Label1.Text = Menu1.SelectedValue;
    }
}

Solution 1

Your menu is not inside your update panel. I believe that means it won't be updated in the AJAX call. The fact that it shows the previous item means that it's rendering, THEN updating the state, instead of vice versa.
