Hi, I want to subclass the built-in DropDownList in ASP.NET so that I can add functionality to it and use it in my pages. I tried doing this with a UserControl but found that it doesn't expose the internal DropDownList (logically, I guess). I've googled for the answer but can't find anything. I've come as far as writing the actual clas...
I just started using ANTS 4 .NET profiler and I am looking for something similar to their Call Graph to implement in our own WinForms application(s). In essence, we are looking for a rich (animated) control that we could use to display the relationship between objects in our application - such as the hierarchal relationships between cust...
We primarily use an ASP.NET environment at work. Right now I'm building an application which uses "Modules", which is just a UserControl, with its' Javascript right in the control, and a link element to the stylesheet for that control.

What's the most elegant way of implementing a DropDownList in ASP.NET that is editable without using 3rd party components. As a last resort I will probably try using a TextBox with an AutoCompleteExtender with an image to 'drop down' the list; or a TextBox overlapping a HTML Select with some JavaScript to fill values from the Select to ...

What is the equivalent to web controls in frameworks other than ASP.Net? Specifically I'd like to know about Java, PHP and Ruby on Rails.

When I have a child .ASCX control that needs to affect something in the parent page I'm not completely sure how I am supposed to handle the event flow in the case where I need to update something in the parent page. What I've always ended up doing is putting logic into the 'Pre_Render' event handler. Since this is processed after any c...

I am creating a website that has 5 different sub-sites each with the same overall look, but each has a different logo and added navigation. What do you feel is a better approach: Use the new nested master page capabilities to create 5 sub-master pages. Use a single master page and dynamically load user controls corresponding to each s...
The problem that I'm having is one that I'm fearing is a design problem, not a coding problem, but I'll ask the question anyway. I have an ASP.NET 2.0 web application that loads two different user controls dynamically based on a value from a database. Inside each of these user controls is basically a FormView control and a SqlDataSourc...
