RadioButton.Checked Error: Control.Checked cannot appear on the left hand side of += or -=

Question

I am having the strangest problem, and I have to be missing something.

Here is my code that is causing the error.

if (radLot.Checked == true)
{
    S         


        

Answer 1

Alternative you can check the CheckState to perform your statement.

 if (radLot.CheckState == CheckState.Checked)
            {

            }

Edit: This will only work when writing a winform application. It will not work with WPF. Use Douglas' answer for WPF.
