I'm writing an app where 3rd party vendors can write plugin DLLs and drop them into the web app's bin directory. I want the ability for these plugins to be able to register their own HttpModules if necessary. Is there anyway that I can add or remove HttpModules from and to the pipeline at runtime without having a corresponding entry in...

I'm struggling to get around the 404 errors from asp.net mvc beta when deploying on IIS 6. I had this working in one of the previews by mapping .mvc in IIS but this no longer works.

I have a report that's being populated from an ObjectDataSource. The report includes expandable/collapsable nodes per user. I'm allowing the viewer to filter the report by setting the FilterExpression on the datasource, then calling ReportViewer1.LocalReport.Refresh(). This is done during PostBack. This filters the results, but the...

In normal WebForms scenario, any root-relative URLs (e.g. ~/folder/file.txt) inside CSS files such as: .form { background-image: url(~/Content/Images/form_bg.gif); } will automatically get resolved during runtime if I specify <head runat="server"> In the referencing page. However, that is no longer happening on an ASP.NET MVC Beta...
We currently do a fair amount or dynamic image generation of png's in ASP.NET using the GDI+ classes in .Net with a no major issues.

Has anyone used jQuery to populate an autocomplete list on a textbox using ASP.NET webforms? If so, can anyone recommend a good method? From my reading so far, it seems like most people are using delimited lists rather than JSON to bring the items back. I'm open to any ideas that will get me up and running rather quickly. ...
Hi, I've got a series of GIFs that I need to crop on the fly, I'm using a HTTP Handler in C# so I can better encapsulate the code - provide caching for the result etc. Currently, when I draw the existing image to a new Image via the Graphics object all the transparency is lost. I've tried various techniques to try and maintain the tra...

I used to have a class in 1.1 for the Datagrid that inherited from the DataGridColumn class. This allowed me to create a check box column with a client-side un/check-all box in the header.

Question: Is there any reason Autocomplete=off on a ASP:Textbox would not be working in IE 7? In case this is the best term for it, the IE Autocomplete feature is that drop down list like thing that drops down from textboxes and shows you past things you have typed in. I need the IE Autocomplete feature to not work at this point for a ...
