DataBinding append to TextBox
I have added 'INotifyPropertyChanged' to a class. Now I want to track changes to a property in a form textbox (TxtLog) by appending the property value string. The form textbox (TxtLog) can also be written to by other classes that append strings.
On another field I use the following code (working):
Status.DataBindings.Add("Text", Fields.Track, "Status");
So code like this would be working:
TxtLog.DataBindings.Add("Text", Fields.Track, "Log");
But this would reset the textbox value. I want the databinding to add to the field 'TxtLog'.
Can this be achieved?

The problem is that I want the databind to append it's value to the existing value in the textbox. This direct link overwrites the value.

did you read the MCVE article? more detail / context / code is needed to see whyTxtLog.DataBindings.Add()isn't behaving as expected; also, post your additional detail as an edit to the body of your question; comments are not well-suited for providing much detail

Do you mean that every change inStatusshould appear in theTxtLog?

Yes by appending to the current value of TxtLog.Also TxtLog can be written to by other classes. A two way bind won't suit my need also.
