Hi
I'd appreciate it some could help me. I want to be able to validate a dollar amount, ie. required, and > 0. Also a percent figure (x) which is required, between 0 and 100, and x <= a limit percent (y) .
Thanks
The >0 rule is already in CSLA, it is CommonRules.MinValue(). For a dollar amount you can probably use a mininum value of 0.01 or 0.005 or something.
The between 0 and y rule can be done a couple ways. You could use both MinValue() and MaxValue() rules if y is known at the time the object is created.
Or you could use MinValue() for the bottom and create a custom rule method that takes your dynamic y value into account. To create a custom rule method, the best infomation source is the CSLA .NET Version 2.1 Handbook, or look at the Project class in ProjectTracker.Library because it implements a custom rule method.
Thanks Rocky
Hi
I must have missed something setting up this rule. Hopefully someone can tell me what I have done wrong.
I've implemented the following in the BO.
private const double minPercent = 0.005D;
private const double maxPercent = 1.00D;
ValidationRules.AddRule(CommonRules.MinValue<double>,
new CommonRules.MinValueRuleArgs<double>("DmfFirst", minPercent));
ValidationRules.AddRule(CommonRules.MaxValue<double>,
new CommonRules.MaxValueRuleArgs<double>("DmfFirst", maxPercent));
and this is in BindingSource_CurrentItemChanged event
this.applyButton.Enabled = _recurrentCharges.IsSavable;
SD.Debug.WriteLine(string.Format("IsDirty: {0}", _recurrentCharges.IsDirty));
SD.Debug.WriteLine(string.Format("IsValid: {0}", _recurrentCharges.IsValid));
SD.Debug.WriteLine(string.Format("IsSavable: {0}", _recurrentCharges.IsSavable));
and when I change the value in my test field, I get the following:
IsDirty: True
IsValid: False
IsSavable: False
So the BO knows it's invalid and the data I entered definitely was invalid. However, the errorprovider doesn't indicate there was an error nor display an error message.
Is there something more I need to do?
Any help would be greatly appreciated.
Thanks
how was it resolved?
I have the same problem where the child object knows its invalid but the error provider doesn't seem to be picking it up.
any ideas would be greatly appriciated
cheers jm
