Question

I have a win form, on which there are several radionbuttons and labels and some other controls wich I am generating at run time. Not what I want when I check a radiobutton, all the radionbutton should be unchecked except the one I checked. This applies to every radiobutton. In short, I want one radionbutton checked at a time.

 private RadioButton GenerateRadioButton(string id)
        {
            RadioButton _radioButton = new RadioButton();
            _radioButton.Location = new Point(32, 20);
            _radioButton.Margin = new Padding(4, 4, 4, 4);
            _radioButton.Size = new Size(130, 36);
            _radioButton.Name = id;
            _radioButton.AutoSize = true;
            _radioButton.Font = new Font("Arial", 16, FontStyle.Bold);
            _radioButton.CheckedChanged += new System.EventHandler(RadioButton_CheckedChanged);
            return _radioButton;
        }

  private void RadioButton_CheckedChanged(object sender, EventArgs e)
        {
          HandleRadioButtinClick(((RadioButton)sender).Name);
            ((RadioButton)sender).Checked = true;
        }

     private void HandleRadioButtinClick(string ctrlId)
            {
                FrmSpace objFrmSpace = new FrmSpace();
                foreach (Control ctrl in pictureBox1.Controls)
                {
                    if (ctrl is Panel)
                    {
                        foreach (Control ctl in ctrl.Controls)
                        {
                            if (ctl is RadioButton && ctl.Name != ctrlId)
                                ((RadioButton)ctl).Checked = false;
                        }
                    }
                }
            }

Here is the code above. The problem with this code is that, when I check a radiobutton, if there is any other radiobutton that is checked, and I try to uncheck it, its checkedchanged event is also fired, that causes all the radiobutton unchecked again. I hope I am clear what I want to convey.

Please provide some solution.

Thanks

Have you tried using a groupbox for all of the radiobuttons? This is the default function you are asking for.

EDIT : to clarify your questions

        // some function
        GroupBox g = createGBox();
        this.Controls.Add(g);
        g.Controls.Add(radioButton1);
        g.Controls.Add(radioButton2);
    }

    public GroupBox createGBox()
    {
        GroupBox gBox = new GroupBox();
        gBox.Location = new System.Drawing.Point(72, 105);
        gBox.Name = "BOX";
        gBox.Size = new System.Drawing.Size(200, 100);
        gBox.Text = "This is a group box";
        return gBox;
    }
