❔ Display error message if value out of limit
Hi, i'm using wpf with mvvm pattern and i'd like to know if it's good to do this in order to display a message error if the value enter isn't good :
public class StepNormalViewModel : StepViewModel
{
private readonly StepNormal _stepNormal;
private double _aV;
public double AV
{
get => _aV;
set
{
if(StepCheck.CheckAV(_aV))
{
_stepNormal.AV = _aV;
_aV = value;
OnPropertyChanged();
}
else
{
//*Display my Error forms*
}
}
}
}public class StepNormalViewModel : StepViewModel
{
private readonly StepNormal _stepNormal;
private double _aV;
public double AV
{
get => _aV;
set
{
if(StepCheck.CheckAV(_aV))
{
_stepNormal.AV = _aV;
_aV = value;
OnPropertyChanged();
}
else
{
//*Display my Error forms*
}
}
}
}
