how to do data binding of dynamically changing data in short time intervals in wpf using mvvm model?

Question

Hi,

I am trying to bind data to my xaml file using mvvm light toolkit but the data i am receiving is dynamically changing in short intervals of time.i am not able to update my view when the data changes.please help.Thanks in advance.

Answer 1

Are you saying that data cahnges so quickly that the view doesn't update quick enough?

Answer 2

No sir.actually the data keeps changing in an infinite loop.i want the view to be updated at every 50 ms.But the problem is that the control passes to the xaml file in the end.So if i use an infinite loop in the model,the program will not reach xaml code.Even if i use a finite loop,the xaml file will show the last updated values.Thanks for taking interest. :)

Hi kanika khetarpal,

You could create a background work, and every 50ms to get the data source, then reset your Binding's data source(DataContext property), on the other hand, you could also implentation the INotifyPropertyChanged interface, and then when you change the value, your UI will update automatically, then you could control the UpdateLayout() time.
