My problem is certainly right on my face but I can't see it... I am building a very simple user control - a 3D ellipse - and I expose two properties: LightColor and DarkColor. I need to bind these properties to the gradient in my user control, but it is not showing any color at all. Here's my code: <UserControl xmlns="http://schemas.mi...

I've got an issue with nested controls not loading properly. I've tried various page methods and nothing seems to work. EDIT: The site compiles and runs fine--it just leaves a blank screen though. Basically I have a wrapper control for a Chart that allows me to select data, bind, and customize the chart with a lot of abstraction. I n...
This should be pretty easy, but it throws VS2008 for a serious loop. I'm trying out WPF with MVVM, and am a total newbie at it although I've been developing for about 15 years, and have a comp. sci. degree. At the current client, I am required to use VB.Net. I have renamed my own variables and removed some distractions in the code b...

I have a C++/CLI System::Windows::Forms::UserControl derived control which should only redraw (a small portion of) itself as new data is fed into it. For some reason though, the OnPaint mechanism is being called even when there's nothing to cause it external to the app. Here's a snippet: void Spectrogram::OnPaint(System::Windows::Forms...
I'd like to use an UpdatePanel in my UserControl. The problem is the .aspx page the control is dropped on will NOT have a ScriptManager. I will need to create the ScriptManager in the UserControl. However if the UserControl is used, say twice on the page, then placing a ScriptManager won't work because you can only initialize ScriptManag...

My boss asked me to set the tab order, and then trap keypress so the user can use enter to navigate controls. I have 2 apps like this to work on. For the tab order, I could not ...
I'm looking for an ASP.NET control to show a series of ad images (maybe 3-5), that will cycle through the ads (with fading, preferably), and have navigation buttons so the user can jump around. Here's an example. Any recommendations? Free is always nice, but I'm willing to spend to get the job done right. Also, I'm using Sitefinity, so ...
