WPF datagrid live-update with button-column

Question

Dear All!

I have a datagrid which contains bid and ask - prices for currency-symbols. The data is updated every seconds. I update the data by creating a new collection of my viewmodel-entities and bind this collection to the datagrid every second.

The problem is: Because my datagrid contains a template-column with a button "buy", this button is also recreated every second! This means, that when the user hovers the button, the hover-styles blinks, as the button is recreated every second. Additionally sometimes the click-event is not fired correctly, if the button is recreated while the user has his mouse-left-button pressed.

Any suggestions, how to solve real-time-update a datagrid with button-columns?

Answer 1

Have you looked into the ObservableCollection?

Represents a dynamic data collection that provides notifications when items get added, removed, or when the whole list is refreshed.

This should only refresh those items that are changed, rather than the whole grid.
