public Form1() VS Form1_Load

What is the different to put the statement inside public Form1() and Form1_Load ?

re: public Form1() VS Form1_Load

The first happens when the Form1 object is CREATED.

The second happens when the Form1 object is LOADED.

I assume you tried this in your project.
What were your results?
You can't go wrong with trial & error. We learn more through mistakes than through successes.

I tend to put things like that in the Load method, only because it's possible that that some controls (or their properties) don't yet exist if when the form is created but not yet Loaded. Which results in a "null reference exception".

I vote for the load event as well.
I try to keep nothing but the InitializeComponent() in the constructor, unless absolutely required.

re: public Form1() VS Form1_Load

If you really want to write something like "Label1.Text = "XYZ"", you can write it in form_load or in the constructor. However if you write that in the constructor, just make sure that you write it after InitializeComponent();

Also I normally assign such properties in the designer rather than in the code file.

Your choice :) ... happy coding.
