How do I display the selected item from my form2 groupbox radiobutton (3 radiobuttons and i can only display one) inside my Form1 texbox.

This is my problem as I only know the code to display 1. if statments didn't work.

Form1:

public void button5_Click(object sender, EventArgs e)
{    
    Form2 fr2 = new Form2();
    textBox1.Text = fr2.receivet(textBox1.Text, fr2.radioButton1);
    
}

Form2:

internal string receivet(string textBox1, RadioButton radio)
{
    return textBox1 = radio.Text;
}

CodePudding user response：

In your code you create a new Form2 instance and take its value. You need to call the shown Form2 instance's function (and set it to public modifier).

CodePudding user response：

No need to create method like receivet, you can directly get RadioButton from Form object

public void button5_Click(object sender, EventArgs e)
{    
    Form2 fr2 = new Form2();
    string radioTxt = ""
    if (fr2.RadioButton1.Checked) 
    {
         radioTxt = fr2.RadioButton1.Text
    }
    else if (fr2.RadioButton2.Checked) 
    {
         radioTxt = fr2.RadioButton2.Text
    }
    else if (fr2.RadioButton3.Checked) 
    {
         radioTxt = fr2.RadioButton3.Text
    }

    textBox1.Text = radioTxt;

}
