The Model part of the code:


Public class UcHDZCQViewModel: Screen
{
Public string MacConnectedStatus
{
The get
{

If (this. Service!=null & amp; & This. Service. TranService!=null & amp; & This. Service. TranService. IsConnected)
Return "connected";
Return "disconnect";
}
}

}
Below is the interface binding code

<10,10,10,10 Label Margin="" Height=" 40 "VerticalContentAlignment=" Center "HorizontalContentAlignment=" Center "Content=" {Binding MacConnectedStatus} "Foreground=" White "& gt;

<style TargetType="Label" & gt;

<style. Triggers>



</style>





Problem description:
This. Service. TranService. IsConnected whether the object is a leap into the mouth open identity, IsConnected is read-only attribute, returns the serialPort class IsOpen property, why leap into mouth off the Label does not follow to update??
