In .net 1.1 I seem to remember I had to declare web controls that I had put on my aspx page also in the code behind in order to access them programatically. Since working in VS 2008 I haven't had to do that - even when working with .net 2 projects. But I just imported a 1.1 project and converted it in 2008 and added a textbox with an i...

I have been developing a silverlight page using just xaml, javascript and html (I literally only have a .html, .js and .xaml file). The problem is, I just realized that it isn't working in any browser EXCEPT Internet Explorer (7 for sure). I have too many lines of code to want to add vb.net or visual c code behind and use the html brid...
I've defined a DataTemplate in a ResourceDictionary. The template need some data (for populating a ListBox). Previously the template was a UserControl and the data was provided by setting the DataContext property. Is there some way of using code-behind for a DataTemplate or is using an ObjectDataProvider to provide the data the only opt...

I realize that by asking this question, I could have started the apocalypse, but a colleague of mine uses a lot of inline coding in their aspx pages, where as I prefer using the code-behind. Is there a right and a wrong way here? ...
Hi All, I have a GridView which is databound to an XML Datasource. For one of the columns I'm using a TemplateField and within it's ItemTemplate I have a CheckBox.

I am developing a large-ish application in WPF/WCF/NHibernate/etc. and have implemented the MVP pattern (although this question is still relevant to MVC) as the core architecture. It feels quite natural to extend and add functionality as well as to come back and make changes on certain bits and pieces, as far as the core architecture is...
In the "code-behind" style of ASP.NET programming, you split your code into two different files, an .aspx file and an aspx.cs file. (That's for C#; for VB, it's aspx.vb instead.) Everyone seems settled on calling the .aspx.cs/.aspx.vb files "code-behind files" or just "code-behinds". The question is: Is there a similarly established term...

I don't ever want the user to actually go to the page, I just want to populate the fields on the page and then render the HTML into a MailMessage that gets sent of to a customer. Currently I have been able to accomplish this by using Server.Execute("~/myrece...
I used to be able to double-click the work area of a dataset to create and load a code-behind page for it, where i could define some custom code to modify or extend the functionality. I don't know if it's because I'm using VS 2008, but now that doesn't happen, and the only file "beneath" the xsd file is the xss code which is auto-genera...

After running WPF animations on dependency properties in code behind, the dependency properties can no longer be set using SetValue. They can only be changed through animations. I want to change a dependency property, some times through short animations, sometimes immediately in code. So how can I remove the animation from a dependency...
