.NET: Forms And Panels

I was fooling around with Panels and Forms yesterday because I was checking out GUIs with .NET. Being one used to Java, I was glad that .NET came along with some good GUI frameworks since, even until now, Java, for me still could not conquer client side GUIs. Creating a stand alone application in .NET using C# and using Visual Studio 2005 as its editor is fairly easy. Just drag and drop controls from the toolkit to the form’s design area.

The problem came when I wanted to use Panels because I wanted to have sub containers within the Form so I could switch between Panels. I kept surfing for more than 3 hours but I still could not find out why when I drag controls to the design area of a Panel, instead of, say a button, a button’s icon will be displayed instead together with the word button instead of a button that looks like in HTML forms.

Turns out, a UserControl control is what you need. Totally wasted quite some valuable time looking for that and it was in a certain forum that mentioned UserControl that I thought I could check it out. To create a UserControl class, right click on the project name in Visual Studio 2005 in the solutions explorer (right side). Choose Add Item > UserControl. Then in the design area mode, you can drag and drop controls from the toolkit to there. I hope this can help newbies who are baffled why Panels do not work as containers like Forms do. In a way, they can be considered containers but for me, they really are just for grouping sets of controls. Kind of like the group boxes.
