As per message subject, does radPropertyGrid support RegularExpressionAttribute for validation? I can't find a mention in documentation.

Hello Andrea,

Actually, this issue is more related to the binding being notified and the TextBox having the error displayed rather than the support of the property grid itself. What you can is:
1. Define the property (for example):

[RegularExpression(@"^[a-zA-Z''-'\s]{1,10}$", ErrorMessage = "Characters are not allowed.")]
       public string Name
       {
           get { return this.name; }
           set
           {
               if (value != this.name)
               {
                   Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "Name" });
                   this.name = value;
                   this.OnPropertyChanged("Name");
               }
           }
       }
 
2. Define the property definition:
<telerik:RadPropertyGrid Item="{Binding Clubs[0]}" >
            <telerik:RadPropertyGrid.PropertyDefinitions>
                <telerik:PropertyDefinition Binding="{Binding Name, ValidatesOnDataErrors=True, NotifyOnValidationError=True, ValidatesOnExceptions=True}" />
            </telerik:RadPropertyGrid.PropertyDefinitions>
        </telerik:RadPropertyGrid>

Thank you, the exception was of course thrown by the underlying database after server-side checks.

Ok i will let properties throw exception and set binding validateonerrors etc on autogenerate property event.

Best regards
