I have three xaml files + their code behind files in my Silverlight (C#) web project. One is the MainPage.xaml, which is what gets rendered in the browser. The other two (lets call them Dot and Box) are custom usercontrols. When the webpage loads, Dots get added to random locations in a sub-canvas in MainPage xml. I would like to add...

In an Asp.net MVC application I'd like to encapsulate the ugly wrapper code (just a literal html opening string and another closing string) we use to make corners and shadows compatible with older browsers (we don't use javascript for performance reasons) in a manner compatible with the visual studio design view. I'd like to put the w...

There are over 270 countries and territories in the world - is 270 too many? When should a ListBox include search or type-ahead capabilities? When should the designer consider something other than a L...

Not only do they not show the image, but when pressed, they redirect back to the root of the site; and the 'onClick' EventHandler doesn't fire. E.g. If I click an ImageButton on the page: http...../MyWebsite.ecom/Project1/frontend/...

I'm just getting my feet wet in Silverlight, and don't really understand the differences and pros/cons of creating a UserControl vs. creating a Control for the same task (as in when you right click on a selection in Expression Blend, for instance). It seems like selecting "Make Into Control" just creates a new template for the base type...
I can't seem to add a user control from an existing solution I've created in visual C++ 2008 Express. I don't see the option located anywhere. Perhaps I'm looking in the wrong area or it's just not available in the express edition. I've followed the advice described here: http://msdn.microsoft.com/en-us/library/114xc3e5%28VS.80%29.aspx ...

Hi, I have a Windows Forms user control, which (for various reasons irrelevant to this issue) are exposed in the designer, much like the panels in a split panel. Most everything works nicely, except for dragging the control. The child controls are created by the user control, and it does not accept new children. The intent is only to al...

I've been working on a web app that could be prone to user abuse, especially spam comments/accounts. I know that RECAPTCHA will take care of bots as far as fake users are concerned, but it won't do anything for those users who create an account and somehow put their spam comments on autopilot (like I've seen on twitter countless times). ...
