If radio button is checked not working

Question

I have four radio buttons where one is called rb_four, and when this is checked, I want something to happen. When I type the following:

if (rb_fourp.Checked)
        {

        }

I get an error saying: The event ToggleButton.Checked can only appear on the left hand side of += or -=. What am I doing wrong here?

For info, this is the xaml code for the radio button:

<RadioButton Name="rb_fourp" Width="150" Height="150" Checked="rb_fourp_Checked">

Answer 1

Checked is the name of the event that is raised when clicking the radio button.

The IsChecked property would be the value you would want to check

if(rb_four.IsChecked){ do some code  }
