Datagrid Double Validation?

[SamCharette]

Hi there! I just started using Blazorise (awesome), so I'm still missing a few concepts I'm sure. I made a simple datagrid that uses the popup edit method. I wanted to do some custom validation, so I added Validator="@checkname" to the field, and a function that checks for valid results.

It works, but when I click save it highlights the invalid field and gives a generic "One or more fields have an error. Please check and try again." error. If I click save again then the custom validation text appears.

Is there a way to go straight to the custom validation errors and skip the generic one?

Maybe you just need to set ErrorText

Try:

void YourMethod(ValidatorEventArgs eventArgs)
{
  eventArgs.ErrorText = "Your error message";

  // other code
}

It's hard to tell without any code sample. If that doesn't help, can you create a small sample to reproduce the issue?

Unfortunately error text does get set. Here's the validation function (I'm new to posting on github, so may not get this quite right)

private void CheckName(ValidatorEventArgs validationArgs)
        {

            ValidationRule.IsNotEmpty(validationArgs);

            if (validationArgs.Status == ValidationStatus.Error)
            {
                validationArgs.ErrorText = "Name is required.";
            }
            else
            {
                string name = (string)validationArgs.Value;
                if (Db.Statuses.Any(x => x.Name == name))
                {
                    validationArgs.Status = ValidationStatus.Error;
                    validationArgs.ErrorText = "Name must be unique.";
                }
            }
        }

The proper validation does appear, but only hitting save a second time. The example datagrid does the same:

It seems this is a bug indeed. Can you open a new issue and I will try to fix it for the 0.9.3 preview.

Sure thing :)
