I searched for a similar question, but haven't seen anyone ask this before. I've been a web developer for a few years now and have never touched windows forms. However, I am taking a job that deals almost exclusively with windows forms. What tips do you have for someone making such a move? Any resources you can share? Thanks! ...
I've got a subclass of DataGridView that adds all the columns it needs in it's own constructor, but when I use this component in the VS designer it insists on generating code to add the same columns on top of the ones added in the component constructor.

I populate a ListBox control with my own objects redefining ToString(). The objects are displayed correctly when I just add those objects using listBox1.Add(myObject). However, if I later change something in this object, no changes are displayed in the listbox. Debugging reveals that an object inside listBox1.Items is indeed changed, but...
I have three classes derived from Control...Class1, Class2 and Class3. Class1 is the parent. It contains a list of Class2 objects, which, in turn, each contain a list of Class3 objects.

As ...

I'd like to use a non-standard font for my .net 3.0 Winforms application. This font might be installed on some of my user's computer, but it will clearly be missing on some others.

I'm displaying a set of search results in a ListView. The first column holds the search term, and the second shows the number of matches.

I run into a very strange problem in my C# 2.0 WinForms app and I'm not even sure if its worth asking SO, because the problem occurs in a strange setup and I don't think that you could reproduce it without my sources, but I'm totally out of ideas. I have a Form with a TreeView on the left and an ListView on the right. The TreeView shows...
