Based on Michael Giagnocavo's feedback, here's a cleaner version of my last post. Thanks Michael.
[ValidationState(ValidationState.Enabled)]
public partial class ExampleElement
{
[ValidationMethod(ValidationCategories.Menu | ValidationCategories.Save)]
private void TestExampleElement(ValidationContext context)
{
var propnames = this.Properties.Select( p => p.Name );
var distinctnames = propnames.Distinct();
if (propnames.Count() != distinctnames.Count())
{
context.LogError("Non-unique property names", "Error 1");
}
var subpropnames = this.Properties.SelectMany( p => p.SubProperties ).Select( p => p.Name );
var distinctsubpropnames = subpropnames.Distinct();
if (subpropnames.Count() != distinctsubpropnames.Count())
{
context.LogError("Non-unique sub property names", "Error 2");
}
}
}
