Topic: Is there some way I can get failed validators on a field?

Topic Description: I have defined multiple validation rules in the designer and that works great. If the validation fails I can use the ErrorString property to get all the error message. But I would like to get access to all the validators that failed. Is that possible?

Awesome! I was going to ask you another question but while typing the question I think I got my answer but you can tell me if I am wrong.

I need to get all the failed validators for all the fields in my object so I am thinking to write a loop that will iterate over the Fields collection of the object. Then on each field I can access the Validators collection.

I will try this tomorrow and let you know if I hit a snag.

P.S. Really appreciate your fast and helpful responses!

Ryan, each field has a Validators property that gives you access to all the validators. The following code shows how you can check if a Validator is valid or not and also do anything further with the validator if required.

foreach (BaseFieldValidator validator in customer.FirstName.Validators) 
{ 
    if (validator is RequiredFieldValidator) 
    { 
        RequiredFieldValidator rf = validator as RequiredFieldValidator; 
        // do something with RequiredFieldValidator 
        // the same process can be used for other types of validators as well. 
    } 
    if (!validator.IsValid) 
    {  
        // this is a failed validator do something here. 
    } 
} 
 

Hope that helps you. If you need any further information/clarification let us know.

Thanks,
