Why do most MVVM databinding properties examples check to see if the current value is equal to previous.
private string name;
public string Name
{
set
{
if(this.name != value) <- why is this check needed.
{...}
}
}
thanks!
In MVVM a property setter triggers the UI update following a property change. Adding this check prevents the UI to refresh (and possibly flicker) unnecessarily.
