Set Default Required Validator in Custom form element

Hi Team,

Is there a way to set the Custom form element required validator to true, so that it will not be necessary for the user to set it fom the CMS everytime they add.

I have created a custom form element inheriting from TextBlockElementBlock. During SetDefaultValues i want to set the Required validator to true as default, but not sure how to do that.

You can override the mehod SetDefaultValues and set value for Validator property which should be RequireValidator. Something looks like:

public override void SetDefaultValues(ContentType contentType)
{
	base.SetDefaultValues(contentType);
	Validators = typeof(RequiredValidator).FullName;
}

I tried this:

public override void SetDefaultValues(ContentType contentType)
{
base.SetDefaultValues(contentType);
Label = "First Name";
PlaceHolder = "John";
this.Validators = typeof(RequiredValidator).FullName;
this.Validators = typeof(EmailValidator).FullName;
}
But it picks the last one, not both.

You need to concat values into a string: this.Validators = string.Concat(typeof(RequiredValidator).FullName, EPiServer.Forms.Constants.RecordSeparator, typeof(EmailValidator).FullName);

Dac - This is pretty much what I'm trying to do, but I'm trying to fill in a custom regex value. I can use typeof(RegularExpressionValidator).FullName to get the checkbox filled, and I'm pretty sure you are supposed to use RegularExpressionAttribute to set the value of the regex, but I can't seem to figure out how to do it. Any advice?
