Cache Master Page in ASP.NET

阅读更多关于 Cache Master Page in ASP.NET

How can I cache the master page in ASP.NET? Unlike user controls, you can't OutputCache a Master page by itself--only as part of a Page. Also, OutputCaching won't help the performance of a toolbar with lots of images anyway. The kind of things that would help include image sprites, client-side caching, using a CDN, using multiple domains for static files, etc. In case it's helpful, I cover those strategies in my book: Ultra-Fast ASP.NET . If you use the @OutputCache directive on the page that uses the master page, then the master page will be cached along with the rest of the page. 来源： https:/

how to change title of aspx page dynamically on page load

阅读更多关于 how to change title of aspx page dynamically on page load

问题 I had set of ASPX pages in which each page had different titles, but I want to put default title for pages which don't have a title. The default title must be configurable. 回答1: If this is classic ASP.NET (not MVC) and you are using MasterPage then you can set default title in Page_Load event in MasterPage : protected void Page_Load(object sender, EventArgs e) { if (string.IsNullOrEmpty(Page.Title)) { Page.Title = ConfigurationManager.AppSettings["DefaultTitle"]; //title saved in web.config }

Why doesn't my jQuery UI datepicker work for postbacks when it works fine on initial page loads?

阅读更多关于 Why doesn't my jQuery UI datepicker work for postbacks when it works fine on initial page loads?

I've been trying to integrate the jQuery UI Datepicker into our ASP.NET WebForms application. The application uses master pages to provide a common look to all pages, and all of the content pages are built inside the ContentTemplate of an UpdatePanel. I've created a user control to wrap the datepicker's functionality and allow setting of the minDate, maxDate, validators, etc. for each date from the codebehind at runtime. I also need to deal with the way ASP.NET generates client element IDs. Over the last week, I've searched high and low, and found lots of tips for getting it to work. Here is a

Can I Include different javascript/css files per Content Page using ASP.NET WebForms Master Pages?

阅读更多关于 Can I Include different javascript/css files per Content Page using ASP.NET WebForms Master Pages?

I have several Content Pages using the same Master Page, that don't all need the same javascript and css files included in the <head> tag. Is it possible to change the contents of the <head> tag from the Content Pages? it is, but I recommend doing it a bit different. I place a content place holder right above the close body tag. Then I populate the required JS scripts per content page. This will allow you to place the scripts at the bottom, but you could also do the same with the placeholder in the header. You can also do so programmatically: HtmlGenericControl js = new HtmlGenericControl(

ASP.NET MVC Master Page Data

阅读更多关于 ASP.NET MVC Master Page Data

The more I use ASP.NET MVC, the more I love it. However, in the case of showing model data on master pages there seems several ways of doing it. I am unsure as to the best solution. My example would be a commerce site where I want to output a list of product categories on every page and also show the status of the visitors cart. In asp.net web forms I would typically do this using user controls each doing their own databinding to retrieve the required data. In MVC all data should be passed by the controller. So regarding the categories the simplest solution would seem to be to pass this in

阅读更多关于 How to dynamically change master page's master page?

I am trying to change the master page dynamically, and although it's easy to do from a content page (overriding OnPreInit ), there is no such event for a master page. Is it possible to introduce this event somehow? UPDATE: I got halfway there by going via the PreInit of the pages at the bottom of the ladder, turns out you can do things like base.Master.MasterPageFile = "/master.Master"; , but for some reason this doesn't load the stuff in the header of the top-most master page, namely stylesheets.
