Problem with Master Page and Virtual Path Provider

阅读更多关于 Problem with Master Page and Virtual Path Provider

问题 I built a deployable master page into a dll and referenced it in multiple ASP.NET Web Applications using a virtual path provider. The problem I'm having is that this really confuses the source view of my aspx pages. Here is the code inside each of my aspx.cs pages which actually attatches the MasterPage to each content page, but as I said, now, my <asp:Content> tags get really confused and I cant CTRL K + CTRL + D my content pages anymore, it throws validation errors on EVERYTHING. HELP!

Cache Master Page in ASP.NET

阅读更多关于 Cache Master Page in ASP.NET

问题 How can I cache the master page in ASP.NET? 回答1: 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. 回答2: If you use the @OutputCache directive on the

问题 I'm struggling to find a solution for a weird issue with ASP.Net Menu control, when used in conjunction with Master Pages. When the user navigates to a page - via. the menu - which inherits from the Master Page, the entire menu just expands and flashes across the screen. Collapses immediately and the page is rendered.... Causes some flickering on the screen, annoying for the users. Now, there are a few work-arounds suggested for this: - Commenting out the tag from the web.config. - giving IDs

How do I access a DIV from javascript, if ASP.NET mangles its ID?

阅读更多关于 How do I access a DIV from javascript, if ASP.NET mangles its ID?

问题 I have a web page that contains a "div" element. On the page, there is javascript to reference the div: document.getElementById('divId') . This was working fine until another developer redesigned the page to use an ASP master page. Now, document.getElementById('divId') returns null. It appears that ASP.net prepends some characters to the names of elements within contents forms when you use a master page. How can I know what the id of the div is when the page loads? Update Allow me to give a

问题 I'm using strongly typed views and autofac for Dependency Injection under ASP.NET MVC2 and I'm trying to get a common dynamic header via dependency injection.

I can't imagine this is an

问题 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? 回答1: 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
