Hello everyone,
just a quick question. I have four radio buttons and only one of each can be selected. I want each of them to run a certain method when they are selected, but if I use "CheckedChanged", then the method will always run twice (one for the button that is losing its checkmark, and one for the button that is gaining it). This is really annoying and the method I am using utilizes hardware, so its expensive to do.

Thoughts on alleviating this problem? Thanks for the advice!

Cast the sender to a RadioButton and see if its Checked status is true. If it is then execute whichever method that RadioButton is supposed to execute. This way it will bypass a RadioButton that has been unchecked.

Here is an example of what I mean:
CODE

        private void radioButton_CheckedChanged(object sender, EventArgs e)
        {
            RadioButton radButton = (RadioButton)sender;

                if (radButton.Checked)
                {
                    // put code here to handle only when a
                    // radio button is checked
                }          
        }

        }




Thanks! The idea worked like a charm
