Hi

VS2017 & Winforms Application

I have a class with the properties of, say FirstName, LastName and Age. Above each property in the class I can define it's position and also the header text to display:

[PropertyOrder(1)],

[DisplayName("First Name")

[Browseable(true)]

public string FirstName {get; set;}

I then create a BindingList<classname> of this class and add several instances to it, the list is then applied to the DataSource of the UltraGrid control.

So my Winform now has a grid on it with 3 columns with the headers of "First Name", "Last Name" and "Age". Because it's a binding list, as soon as the user updates the data / adds new rows, the list is updated, I can then iterate through this list and save the data... All is fine... Except Validation.

So what is the best way to validate these 3 fields.. ?

Can I put [MaxLength(50)] above the two name properties to set the max length and Min/MaxValue on the Age so it's between 0 and 150 ?

I want to validate the data before it's saves to the Database, and get errors because the string is too long or the age is way to high!.

Many thanks
