ASPxClientEditValidationEventArgs.errorText Property

Gets or sets the error description.

#Declaration

TypeScript
errorText: string

#Property Value

Type Description
string

A string representing the error description.

#Remarks

The errorText property can be used to provide text explaining why validation failed. If the ASPxClientEditValidationEventArgs.isValid property is set to false, the text will be displayed within a specific error frame.

#Example

The code sample below demonstrates how you can perform custom client-side validation to limit an permissible user age. For this purpose, the ASPxClientEdit.Validate event is handled.

function OnBirthdayValidation(s, e) {
     var birthday = e.value;
     if(!birthday)
          return;
     var today = new Date();
     var msecPerYear = 1000 * 60 * 60 * 24 * 365;
     var years = (today.getTime() - birthday.getTime()) / msecPerYear;
     if(years < 14) {
          e.isValid = false;
          e.errorText = "You should be at least 14 years old.";
     }
}
