检查Radiobutton已经改变了WPF

Question

In my WPF application i have:

-> TextBox (textChanged)

-> 2 radio buttons

-> ListView with content. "Author","Title".

I need to allow searching from Listview.

My question is: How i should check if radiobutton check is changed?

Answer 1

As mentioned in the comments MVVM is prefered for WPF then you would bind to the IsChecked Property.

private bool _RadioButtonChecked;
public bool RadioButtonChecked
{
    get => _RadioButtonChecked;
    set
    {
        _RadioButtonChecked = value;
        //Refresh filter here
    }
}

Xaml binding:

<RadioButton Content="RadioButton" IsChecked="{Binding RadioButtonChecked}"/>

Aside from that there is are Checked and UnChecked events that you can use.
