Wpf datatrigger binding not updating
Any existing grouping, filtering and sorting functionalities will apply to the new entry.
In this particular case, the item entered in the above image will be displayed as the second item within the Text Box.
Data binding can also mean that if an outer representation of the data in an element changes, then the underlying data can be automatically updated to reflect the change.
For example, if the user edits the value in a Text Box element, the underlying data value is automatically updated to reflect that change.
As described in the last section, the direction of the data flow is determined by the value of the Mode property of the binding.
