Answer 1

Hello,

One would think this a simple task while there are things to consider like

• Position of a control or multiple controls
• Events for the control as simply place a control on a form generally we want to interact with it except perhaps a label and maybe a image.

I put together two code samples that are pre-done.

First project/code samples creates a single button with events for click, create multiple buttons with interaction with a ListBox and gets captions for buttons from database which could also come from say a text file etc.

Second code sample is rather complex which works with a custom control - grouped-radio buttons.

Find these code samples in the following GitHub repository. Note I used Visual Studio 2019 to write these code samples, one with classic framework and the other with .NET Core Framework.

Perhaps you just want to use a UserControl. If you can do what you need to do using a UserControl then that would be quite easy.
