Login hidden and updatePanel (ASP.NET AJAX history)

How can I update the input hidden inside the UpdatePanel on the AsyncPostBack?

The user clicks a button outside the panel. The method associated with the click event updates the input value (has a runat = "server" property).

I cannot update the value of this input.

I need to store the value for use in the next postback. Perhaps I can use a session to store this value.

Any advice?

Thanks!

In no case. The only way to update the input is to make a complete post. Better to use the Session object.

Since its postback, you might have to check in the post back event and do an update. If not, you may need to override the previous event. See http://msdn.microsoft.com/en-us/library/dct97kc3.aspx

If you need to update the refresh panel (and its contents) based on a user click on a button that is not on the refresh bar, add a section to the refresh bar as shown below:

<asp:Button ID="btnOK" runat="server"/> 
<asp:UpdatePanel ID="pnlMyPanel" runat="server">
    <ContentTemplate>
        <!-- Content to get updated -->
    </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="btnOK" />
    </Triggers> 
</asp:UpdatePanel>

The triggers section in the example above says to update the refresh panel if a button is clicked.

You might want to try <asp:HiddenField>

instead <input type='hidden' runat='server'>

. I think the asp.net version is more post-back aware.
