Question

I have a HiddenField which changes value depending on what the user clicks. On the same page I have an invisible Panel with a User Control inside of it. I want to pass this value to the control when the Panel becomes visible.

The code:

<asp:HiddenField ID="hfdSelectedDeliveryAddressID" runat="server" Value="0" />
<asp:Panel ID="pnlOrder" runat="server" Visible="false">
    <uc3:AddressBook ID="AddressBook1" runat="server" AddressID="[value]" />
</asp:Panel>

I guess I’m asking what the syntax is to insert $("#<%= hfdSelectedDeliveryAddressID.ClientID %>").val() where “[value]” is. Help?

With Visible="false" set, you must be going back to the server to set Visible = true, right? When you set Visible = true, set the property as well:

AddressBook1.AddressID = hfdSelectedDeliveryAddressID.Value;
AddressBook1.Visible = true;
