The ValidationSettings.Display property is set to Dynamic if a user didn't modify it and a corresponding model property has the Required or RegularExpression attributes

Previously, the editor rendered extra space for its validation message (text and icon) according to the ValidationSettings.Display property value and didn't take into account a model property's Required or RegularExpression annotation attributes.

Starting with v18.2, the editor automatically sets the ValidationSettings.Display property value to 'Dynamic' and renders extra space for the error message if validation fails when the following conditions are met:

C#
void Application_Start(object sender, EventArgs e) { ASPxWebControl.BackwardCompatibility.OptimizeErrorMessageDisplayForDataAnnotationValidationInEditors = false; }
