Is is possible to build a form, accept parameters and from THAT construct a new .ascx page AND the code behind for that page? What I'm proposing is having some code snippets that just need parameters added and can then be used to create a web user control that can be added to existing pages. This .ascx file would be a real file after creation, not dynamic every time.

I have an ASP.NET 3.5 web page that tries to retrieve a DataSet from a cache object. If not available, it will be retrieved from the database (SQL Server 2005) and I will insert the newly retrieved DataSet into the Cache object. The problem is that I want to insert the DataSet with a SqlCacheDependency so that as soon as the database table changes, my ASP.NET application will be notified. Something that is accomplished in @PageOutput using SqlDependency="CommandNotification". SqlCacheDependency constructor has two overloads, neither of which seems to be able to resolve my problem. I have no idea where I can set that magical CommandNotification!
View 6 RepliesI've currently got a feedback form where the details are sent to my emila address. I've got the following text boxes:Name.text, Users.text & body.text.
