Binding constantly updated string with textbox

Question

I wish to bind a String with a textbox. The string is constantly being updated in a thread:

String inputread;

    public event PropertyChangedEventHandler Prope         


        

Answer 1

In threadFunc() function, you set the value directly to inputread (lower case), it's a field and have no call to OnPropertyChanged. You can change the code in threadFunc() to InputRead=plc.InputImage[1].ToString(); I hope it works for you.

Answer 2

You need create a property and bind TextBox to the property

private string _Inputed;
public string Inputed
{
    get { return _Inputed; }
    set 
    {
        if(Equals(_Inputed, value) == true) return;
        _Inputed = value;
        this.OnPropertyChanged(nameof(this.Inputed));
    }
}

void threadFunc()
{
    try
    {
        while (threadRunning)
        {
            plc.Read();
            this.Inputed = plc.InputImage[1].ToString();
        }
    }
    catch (ThreadAbortException)
    {
    }
}

public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string name)
{
    PropertyChangedEventHandler handler = PropertyChanged;
    if (handler != null)
    {
        handler(this, new PropertyChangedEventArgs(name));
    }
}

XAML

<TextBlock Text="{Binding Path=Inputed}"/>
