I have some code on my ASP page which looks like this: <asp:UpdatePanel runat=server

  • 0

I have some code on my ASP page which looks like this:

<asp:UpdatePanel runat="server" id="updatepanel1" UpdateMode="Conditional" onload="updatepanel1_Load" ChildrenAsTriggers="false">
<ContentTemplate>
<asp:HiddenField id="sendingRequest" runat="server" Value="0" />
....
</ContentTemplate>
</asp:UpdatePanel>

I also have some javascript on my page which does this, to trigger the update of the updatepanel:

var sendingRequest = document.getElementById("<%=sendingRequest.ClientID%>");
sendingRequest.value = "1";
__doPostBack('<%= updatepanel1.ClientID %>', '');

Everything works fine up to now, but in my updatepanel1_Load event, I try to set the value back to “0” :

sendingRequest.Value = "0";

This value never gets updated and set back to 0 on the client after the postback, and I can’t figure out why!

Can anyone help? Thanks

    If you’re having problems with a hidden field, you could use a TextBox instead. Hide the textbox with css (display: none;) to achieve similar results to a hidden field. Its not exactly pretty, but its a workable workaround.
