When the command fires, the CommandArgument comes back unevaluated - it is the string a=<%# Eval("a")%>&b=<%# Eval("b")%>, not a=5&b=6 as I want. What's wrong with how I'm doing this?
I have an aspx page which retrieves messages from a database. One message is an instruction to the user to copy some xml from a file. I'm trying to tell the user that they need to copy the code lying between "<?xml" and "</reports>".
The problem is that when the message is displayed to the user the line containing the quoted code is missing. It appears that the page is taking "<?xml" and "</reports>" as instructions to the page and trying to action the tags. I just want to display these characters on the my page. how I can get these code snippets to display?

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
If I look at the Razor View Engine, then I see a very nice and concise syntax that is not particularly tied to generating html. So I wonder, how easy would it be to use the engine outside asp.net in a "normal" .net environment for example to generate text, code,...
how to fix "Method not found: 'Void System.Web.Mvc.ViewContext..ctor(System.Web.Mvc.ControllerContext, System.Web.Mvc.IView, System.Web.Mvc.ViewDataDictionary, System.Web.Mvc.TempDataDictionary)'." exception.

As ASP.NET MVC has a pluggable view engine architecture, and XAML is an object descriptive mark-up that, given the right processor/ parser, can generate an appropriate UI...are there plans/ efforts to create a view engine that can turn XAML into HTML?
Personally, I think this would help to re-enforce the efforts the WPF/ Silverlight people have gone to in providing a means of seperating the view from the model/ business logic between designers and developers (via Visual Studio and Expression Blend)...
Seems like a logical step to me, but not knowing XAML as well as I should, I'm wondering if feasable, or even relevant.
I have used the xslt code from Steven Sandersons book 'Pro ASP.NET MVC2 Framework' for the xslt view engine and that is working perfectly. However I am now looking at using a master page for the header, footer, and navigation sections and only need to use my other xslt files to populate the content part.
I'm working trying to realize a requirement where the pages should be 'configurable' at runtime (per client), stored in a database - a requirement that I have no say in Anyway, the current plan is to use the Razor view engine and 'load' the 'pages' dynamically. I have a basic sample working using a VirtualPathProvider and VirtualFile that serves up Raz'pages' on the fly.The question I have if there is a better approach when I have the Razor 'pages' stored in a dB (or any other repository)?
There seems to be some constraints and concerns when I check other postings. For example:'If a Web site is precompiled for deployment, content provided by a VirtualPathProvider instance is not compiled, and noVirtualPathProvider instances are used by the precompiled site.' (from http://msdn.microsoft.com/en-us/library/system.web.hosting.virtualpathprovider.aspx )
I was going through the spark view engine documentation and found a lot of literals showing up in code for which I couldn't find any references. For e.g. ! , #, $ , !$ , ... What are these for? What do the combinations mean? When do they come into use? Am I missing any more literals that precede or comes after {
Is there any way to use placeholder similar to WebForms in NVelocity View Engine (.vm files)? Today I've got a component containing everything for the <head>, but I wish to specify additional tags from each view page like it can easily be done in ASP.NET WebForms / MVC:
If this is not possible directly trough NVelocity View Engine, do I have any other alternatives other than using a blank MasterPage and adding all markup in each view page?
Trying out the Razor view engine and for some reason my generic helper methods are breaking. For example:
public static class UrlHelperExtensions { public static string NonGenericHelper(this UrlHelper helper, Type controller) { return controller.Name; } public static string GenericHelper<TController>(this UrlHelper helper) { return typeof(TController).Name; } }
Works as expected:@Url.NonGenericHelper(typeof(ProjectEuler.UI.Models.Home))Breaks with the following exception:
@Url.GenericHelper<ProjectEuler.UI.Models.Home>() "CS1502: The best overloaded method match for 'Microsoft.WebPages.WebPageUltimateBase.Write(Microsoft.WebPages.Helpers.HelperResult)' has some invalid arguments"
The only workaround I could find is treating it as a "multi-token statement":
how do I change the view engine from aspx to razor in an existing project? If I just change the file extension to cshtml I always get "The controller for path '/path/About' was not found or does ..."
How do you modify a ASP.NET MVC 2.0 project to work with the Spark View Engine?
I tried like described here:

But somehow it still tries to route to .aspx files.
Here the code of my global.asax:

I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.
To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".
Where i can find documentation about expressions and syntax of WebForms view engine?And what is the difference between <%: expression %> and <%= expression %>
I try to use HtmlHelper.TextBoxFor with spark view engine but view crashed with exception "Dynamic view compilation failed. 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'TextBoxFor' and no extension method 'TextBoxFor' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found(are you missing a using directive or an assembly reference?)".
It is my _global.spark: <use namespace="System"/> <use namespace="System.Linq"/> <use namespace="System.Text" /> <use namespace="System.Web.Mvc"/> <use namespace="System.Web.Mvc.Html"/> <use namespace="System.Web.Routing"/> <use namespace="System.Linq.Expressions" /> <use namespace="MyModels" /> In spark-view using: ${Html.TextBoxFor(m => m.UserName)}
