The following code example demonstrates how the CheckAlign property can be changed at run time. The check box portion of a RadioButton is moved to the right or left of the text when the Checked value changes. This example requires that a RadioButton control has been instantiated on a form and that a reference to the System.Drawing namespace has been included.
private void radioButton1_CheckedChanged(Object sender, EventArgs e) { // Change the check box position to be opposite its current position. if (radioButton1.CheckAlign == ContentAlignment.MiddleLeft) { radioButton1.CheckAlign = ContentAlignment.MiddleRight; } else { radioButton1.CheckAlign = ContentAlignment.MiddleLeft; } }
