Example
[Visual Basic, C#, C++] The following example evaluates a ListBox selection and the Checked property of a RadioButton. When a specified item is selected from the list box, the PerformClick method of another RadioButton is called. This code assumes that two RadioButton controls and a ListBox have been instantiated on a form.
[Visual Basic] Private Sub ClickMyRadioButton() ' If Item1 is selected and radioButton2 ' is checked, click radioButton1. If (listBox1.Text = "Item1") And radioButton2.Checked Then radioButton1.PerformClick() End If End Sub [C#] private void ClickMyRadioButton() { // If Item1 is selected and radioButton2 // is checked, click radioButton1. if (listBox1.Text == "Item1" && radioButton2.Checked) { radioButton1.PerformClick(); } } [C++] private: void ClickMyRadioButton() { // If Item1 is selected and radioButton2 // is checked, click radioButton1. if (listBox1->Text->Equals("Item1") && radioButton2->Checked) { radioButton1->PerformClick(); } }
