radiobuttons on different tabcontrol stay selected

Please read de question as it´s not a duplicate. I have a winforms app i C# witch has a tabcontrol with 3 tabs. Each tab has 4 radiobuttons. If i run the app, the radio buttons work fine within the same tab, but when i select another tab the selection remains in the first tab. I tried to clear all checked radiobuttons when changing tabs but for some reason it does not work. The code is use is:

private void UncheckLayouts(TabPage activePage)
{
    foreach (Control control in tabControl1.Controls)
    {
        if (control is RadioButton)
        {
            RadioButton rb = control as RadioButton;
            rb.Checked = false;
        }
    }
}

private void radioButton1_Click(object sender, EventArgs e)
{
    UncheckLayouts(tabControl1.SelectedTab);
}

private void radioButton2_Click(object sender, EventArgs e)
{
    UncheckLayouts(tabControl1.SelectedTab);
}
...

I tried like this too:

private void tabControl1_Deselecting(object sender, TabControlCancelEventArgs e) {
    foreach (var ctrl in e.TabPage.Controls) {
         if (ctrl is RadioButton) {
             RadioButton tb = ctrl as RadioButton;
             rb.Checked = false;
         }
    }
}

EDIT: new code.

public Form2()
{
    InitializeComponent();
    tabControl1.Selected += TabControl1_Selected;
}
private void TabControl1_Selected(object sender, TabControlCancelEventArgs e)
{
    foreach (var ctrl in e.TabPage.Controls)
    {
        if (ctrl is RadioButton)
        {
            RadioButton tb = ctrl as RadioButton;
            tb.Checked = false;
        }
    }
}

But no solution works. All radiobuttons were added to each tab with the designer.

Can anyone help please. Thanks in advance,

You can use the following code，I tested that it was working fine 

private void InitializeComponent(){
           ........
 tabControl1.Selected += TabControl1_Selected;
}



private void TabControl1_Selected(object sender, TabControlEventArgs e)
{
    foreach (var ctrl in e.TabPage.Controls)
    {
        if (ctrl is RadioButton)
        {
            RadioButton tb = ctrl as RadioButton;
            tb.Checked = false;
        }
    }
}
