ASP.NET MVC 2 validation LINQ to SQL
- by Chino
Currently I have a DataModel object which contains my linq to sql classes(a dmbl file). Currently I use a partial class to validate the incoming input. For example
public partial class User : IEntity
{
public NameValueCollection CheckModel()
{
return GetRuleViolations();
}
/// <summary>
/// Method validates incoming data, by given rules in the if statement.
/// </summary>
/// <returns>NameValueCollection</returns>
private NameValueCollection GetRuleViolations()
{
NameValueCollection errors = new NameValueCollection();
if (string.IsNullOrEmpty(Username))
errors.Add("Username", "A username is required");
// and so on
return errors;
}
}
Now what I want to try to do is add validation attributes to the fields. For example I want to try to add the required attribute to the field Username instead/in addtion of using the validation I currently have. My question is how can I achieve this because the dmbl file is auto generated. Or maybe it is not possible and should I use a different approach?
