How can I get it? 回答1: Create a public property inside the ascx and set it at the same time you set in the aspx page.

问题 I have an ascx control bound to a datasource with frequently changing data. Is there a quick way to have an ascx control postback, rebind and refresh itself every X seconds. The ascx control is in an update panel. 回答1: Use a timer control from the AJAX toolkit since you are already using it: <asp:Timer ID="tmrPolling" runat="server" Interval="10000" ontick="tmrPolling_Tick"></asp:Timer> Add a trigger to your update panel like: <Triggers> <asp:AsyncPostBackTrigger ControlID="tmrPolling"

问题 I have a user control ( gallery.ascx ) and I want to use the photo.ascx control in the gallery control. I've added this register at the top of gallery.ascx , but it still can't find photo: <%@ Register TagPrefix="ssctrl" TagName="photo" Src="controls/photo.ascx" %> Any ideas? 回答1: In case anyone is wondering, the Register is correct, my photo user control tag was just not formed properly. I did have it as: <ssctrl:photo ID="Photo" Key="<%# Eval("PageTemplatePK") %>" runat="server" /> and the

问题 I have a user control which uses objects as inner properties (some code is below).

ASPX Page <uc1:StepControl ID=

问题 I'm onto a real head scratcher here ... and it appears to be one of the more frustrating topics of ASP.NET. I've got an assembly that implements a-lot of custom Linq stuff, which at it's core has zero web functionality. I have an additional assembly that extends this assembly with web specific behaviour. The web specific behaviour comes with a couple of user controls marked up inside ASCX templated UserControls. I'm having trouble putting a nice finish on this assembly so that it is simple to
