You should write a universal method, which, when selecting radioButton will be called for each radioButton , and inside the method we will change their states:

 void radioButtons_CheckedChanged(object sender, EventArgs e) { RadioButton currentRadioButton = sender as RadioButton; // на кого кликнули if (radioButton != null) { // пройдем по всем RadioButton нашей формы и поменяем состояние foreach(var radioButton in this.Controls.OfType<RadioButton>()) { radioButton.Enabled = false; // заблокируем каждый } currentRadioButton.Enabled = true; // разблокируем выбранный } }

Thus, after selecting one radioButton rest will be blocked. In order for this method to be called on all radioButton placed on the form, it is necessary in the properties of these components, each to specify the method that will be called for the CheckedChanged event — call the radioButtons_CheckedChanged method.

Good day. To deactivate (lock) the radio button, after selecting, you need to write a trace. code: the function is created automatically after clicking the radio button several times with the mouse

 private void radioButton1_CheckedChanged(object sender, EventArgs e) { Enabled = false; //деактивируем radio button }

To deactivate other radio buttons, you need to deactivate their trace. in the following way:

 private void radioButton1_CheckedChanged(object sender, EventArgs e) { Enabled = false; radioButton2.Enabled = false; // название radio button . деактивация = деактивировать radioButton3.Enabled = false; }

in order to cut down the entire form, you just need to write a trace to the function. line:

Form1.ActiveForm.Dispose ();
