Hi Pat Nadis, 

 

Greetings from Syncfusion. 

 

We are glad to know while removing the nuget in your project it resolves the reported problem. Also we have IsChecked property in Xamarin.Forms SfCheckBox control which is a IsNullable value type and it is updated by StateChanged event. Hence, we assume that handling IsChecked property by sample level as per the below code example. 

 

CodeSnippet: 

<sfCheckBox:SfCheckBox StateChanged="checkBox_StateChanged" 

                       TextColor="Red"  

                       IsThreeState="True" 

                       IsChecked="True" 

                       x:Name="checkBox"  

                       Text="Checked State"/> 

 

private void checkBox_StateChanged(object sender, Syncfusion.XForms.Buttons.StateChangedEventArgs e) 

{ 

    if(e.IsChecked != null) 

    { 

        checkBox.Text = (e.IsChecked==true)? "Checked State" : "UnChecked State"; 

    } 

    else 

    { 

        checkBox.Text = "Intermediate State"; 

    } 

}
