CheckedChanged not triggering

I am trying to create a winform application. Accidentally I found that Radiobutton.Checked event is fired when we programmatically assign true to RadioButton.Checked. But it is not fired when we programmatically assign false to Radiobutton.Checked. But it fires, when we manually checked/unchecked it. Here is a sample Code. Copy it,compile it and run it to check
using System.Windows.Forms;
using System;
using System.ComponentModel;
using System.Windows;
namespace Temp
{
public partial class Form1 : Form
{
public Form1()

InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
//radioButton1.Checked = true;
//radioButton2.Checked = true;
radioButton1.Checked = false;
radioButton2.Checked = false;
}
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
System.Windows.Forms.RadioButton tempRB = (System.Windows.Forms.RadioButton)sender;
MessageBox.Show(tempRB.Name + " : " + (tempRB.Checked ? "Checked" : "Unchecked"));
//radioButton2.Checked = !radioButton1.Checked;
}
}

Can anybody give an explanation about this. And also help me on how to fire RadioButton.Checked event when it got assigned false programmatically.
Note: I am using .net 3.5,Windows 10.
EDIT:
I am adding slightly modified code. In this "Uncheck" button didn't trigger anything. But "Check Both" triggers two times CheckedChanged event. Check this code

How to bind data to a custom Windows Form using SplitContainer?

I've created a form that I call a ListChooser. It looks like so:
It consists of a System.Windows.Forms.Button and .TextBox.
Clicking on the Button (shown above with the text "Fruits") causes a dialog to popup and some selections are made and the TextBox is populated, like so:
My problem is I can't figure out how to set a System.Windows.Forms.Binding to this TextBox. I think the complication is that it's not just a TextBox, it's 2 components in one. (I know how to data bind with just a standalone TextBox). If I go to the TextBox > Properties > DataBindings > Advanced > ..., All entries listed under Property are not selectable:
I've tried this which has no effect:
private System.Windows.Forms.BindingSource myBindingSource;
this.myBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.myBindingSource.DataSource = typeof(Foods) // Fruits is a Property of Foods;
myListChooser.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.myBindingSource, "Fruits", true));
How do I do this?
ListChooser.Designer.cs:

How to I make the application and all the corresponding popups look exactly the way they look in VB ?
The nee Windows ,when not active tend to go behind the application. I want them not to go outside the Parent Window.
How can I fix these?

Instead of
MatRef.Show();
write
MatRef.ShowDialog();
If that not working than add one more line before that
MatRef.TopLevel = false;

GUI White becomes Transparent

By setting the TransparencyKey of the form, transparency is enabled. Default color for transparency is white.
Remove this line from the InitializeComponent () function
this.TransparencyKey = System.Drawing.Color.Transparent;
and the white on your form will no longer be transparent.

How to access text button outside Form.cs class (I mean in Program.cs)

I have created a Form in c# windows. My form contains a button and a text box and it 's name is textbox2 here and it contains code like this in Form1.Designer.cs :
this.textBox2.Location = new System.Drawing.Point(683, 14);
this.textBox2.Name = "textBox2";
this.textBox2.Size = new System.Drawing.Size(100, 20);
this.textBox2.TabIndex = 22;
Now i have created another class called Programss.cs which will do some task and as the task finished i want to print on my form something like this:
textBox2.txt= "Task finished"; //it should print on the textbox of my Form1.cs
How to access this textBox2(which can only be accessed currently in Form1.Designer.cs) in Programss.cs and my other classes ?
EDIT: After Philip Stuyck's comments:
Here is my Form1.cs code :
namespace S
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
//please see here
public string TextMessage
{
get { return textBox3.Text; }
set { textBox3.Text = value; }
}
private void btnStart_Click(object sender, EventArgs e)
{
btnStart.Enabled = false;
// StartServer();
}
private void btnClose_Click(object sender, EventArgs e)
{
}
}
}
And Program.cs is :
namespace Senter code here
{
class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();

Application.Run(new Form1());
/////////////////////////////////////////////////////////////////////////////////////

It dont give any error but it do not print anything in textBox3 .
NOTE: Please note that first i run the winform code i click a button and when i click the button some proccess will run which will further print the text in the textbox. (I feel like my textmessage is not intialized by my message passed to it).

Make sure that textBox2 is public.(can be done in the designer)
Keep a reference to Form1 when you create it and access textBox2 via that reference.
Form1 theForm = new Form1();
... //do stuff
theForm.textBox2.Text = "Task finished";
This is not the most elegant approach to this, but it should work.
An alternative is like this :
public partial class Form1{
public string TextMessage{
get{
return textBox2.Text;
}
set{
textBox2.Text = value;
}
}
}
and in program.cs
Form1 theForm = new Form1();
... //do stuff
theForm.TextMessage = "Task finished";
your code will not work because
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
is never executed.
Application.Run(new Form1());
returns only when the form is closed and then the application will end.
Following will work:
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
Application.Run(theForm);
But I have the feeling you don't quite understand the framework.
Application.run, will make your application enter into a message loop which makes the application receive window messages.

One way you could do this is to have a method accessible in your Form1 that sets the textBox name to whatever you want. For instance:
public static void SetText (string message)
{
TextBox2.Text = message;
}
You would then call this from your Program.cs class:
Form1.SetText("Whatever text you want the text on the Form1 - TextBox2 to say");
This is the poor man's way of changing the text. There is a more detailed explanation on this other post if you need more details.

As I understood you want to print end result on textBox2.txt textbox, right? So you want to execute some methods on Programss.cs and once execution is finished you want to show "Task finished" on textBox2.txt.
If I am not wrong, what you have to do is return a value from a method from Programss.cs class. You have to call this method from Form1.Designer.cs class. Based on return value you can do whatever you want.
Hope this will be helpful.

You are creating two separate forms, setting text on the second, and expecting it to appear on the first.
Do this:
Form1 theForm = new Form1();
theForm.TextMessage = "Task finished";
Application.Run(theForm);
