Creating a WPF Custom Control

I'm currently creating a user interface using WPF and would like to display a pie-chart on my window. As far as I can see, this will involve creating a custom control - it is not a scenario in which applying styling or templating to an existing control will be sufficient. I've read several articles on custom controls and all of those whi...

My control is "not allowed here because it does not extend class 'System.Web.UI.UserControl'"

Hi there So I have another noodle-scratcher (for me anyway). I'm trying to create my own custom control in a CMS I only have partial source code for (i.e. samples the vendor has supplied to me).

Custom MFC control prevents dialog creation

I have a custom MFC control, subclassing CWnd. Other than providing OnPaint and PreSubclassWindow implementations, it overrides no default functionality and does nothing weird in construction except registering a window class in the constructor.

Adding visible elements to a custom Panel in Silverlight 3

As I understand it, a Panel isn't meant to have any visible "chrome." The StackPanel, Grid and Canvas don't have any visible elements (with the exception of the gridlines, which they say are only for debugging layout.) In my example, I am going to create a Custom Panel that uses Attached Properties to lay out its children controls. Ho...

Custom Controls

I seem to be having problems with custom controls in WPF. I want to have a simple validating textbox where I can only put doubles. In Forms it was easy, just create a custom control, inherit from TextBox and handle the appropriate events. Is this the way to go in WPF?

How do I go about getting a page to restart processing in C#?

I'm working with a CMS which allows you to develop your own custom controls which get dynamically included at runtime. So I have a custom control which alters a datasource (NHibernate cache) and as I'm at a point in the process where the CMS has already read this data from the cache, I need to restart the processing of the page somehow s...

Reusable Custom Control with Properties

I have built a Custom Control Class that makes it much easier to build a side bar element in my html. The problem I am running into is that when I set the "Text" property, the last time I set it gets used for every instance of the control on my page. This is my first time doing this, so I'm assuming I'm missing something basic. Namesp...

Is there a User Control Library project type in VS 2010

I was looking for it all night, but it seems that the project type is not on vs 2010. But the main problem is, I want to make a custom control (or a user control compiled to a dll, if vs 2010 does not have the custom control library feature). Unluckily, I was not able to find any article for 2010 but only for 2008, which is pretty much ...
