问题 Anyone know of a link to a good article/tutorial for getting started using jQuery for AJAX calls rather than ASP.NET AJAX? I'm trying to avoid using UpdatePanels entirely in this app, which I haven't been able to accomplish in the past. 回答1: The most complete article I've ever found about this topic http://www.codeproject.com/KB/ajax/AjaxAndAspNET.aspx It avoids update panel, script manager and viewstate. 回答2: Here are few links: A Look Into JQuery API http://gridviewguy.com/Articles/407_A

问题 Can anyone recommend a dropdownlist control for asp.net (3.5) that can render option groups? Thanks 回答1: I've used the standard control in the past, and just added a simple ControlAdapter for it that would override the default behavior so it could render <optgroup>s in certain places. This works great even if you have controls that don't need the special behavior, because the additional feature doesn't get in the way. Note that this was for a specific purpose and written in .Net 2.0, so it

问题 For efficiency purposes I am wondering if a file or text in a textarea still gets transferred to the server if you omit the name attribute or set it to null. eg <input type="file" id="file" name=""> <textarea id="text" name=""> I notice that the data is not available at the server if you do this. 回答1: The W3C specification, if I understand it correctly, mandates that every form input element has a name attribute specified. Otherwise that element will not be processed. Source 回答2: No. I

问题 I am working on rewriting URLs Urlrewriting.net, and have run into what seems to be a common problem but I can seem to fix it. I'll present a simplified case. The URL rewriting is working perfectly with the rule: <urlrewritingnet rewriteOnlyVirtualUrls="true" defaultPage="default.aspx" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07"> <rewrites> <add name="catalog" virtualUrl="^~/catalog/(.*)/(.*).aspx" rewriteUrlParameter="ExcludeFromClientQueryString"

问题 I have a specific page (sitecore content item) in my web application composed of a sitecore layout and many sublayouts. One of those sublayouts is a user control that I would like to have refreshed once a certain button is clicked. I would like only that sublayout to be refreshed and the rest of the page to remain unchanged (typical ajax situation here). How do I accomplish this with sitecore when all of my sitecore content items are directly related to a full page in my web application
