  It is absolutely clear how this works.

  When using a struct, and with GetStandardValuesSupported configured to return false, the output markup is set to

  <cc1:MyDPoint runat="server" DPoint-X="5" DPoint-Y="5" DPoint-Z="5"></cc2:MyDPoint>

  This will fail compilation every single time, and correctly, because the generated code is effectively trying to do

  SomeMyDPointObject.DPoint.X = 5;

  With structs, that simply cannot (and should not) work.

  However, if you configure GetStandardValuesSupported to return true, the designer writes out

  <cc2:MyDPoint runat="server">
    <DPoint X="5" Y="5" Z="5"></DPoint>
  </cc2:MyDPoint>

  which is clearly equivalent to

  var temp = new DPoint( 5, 5, 5 );
  SomeMyDPointObject.DPoint = temp;

  This is clearly going to work perfectly every time.

  I think that's the UI differences, but it shouldn't effect the real result:(

  Do u think so?

  It's not really UI differences. Changing the implementation of the converter appears to change the behavior of the designer, which is perhaps to be expected.

  Whether I like it or not is immaterial. This seems to be how it works, so you either live with it, or raise a question / bug report on the Microsoft Connect site.

  If there's a bug here, it is the fact that the designer is prepared to emit code that it should know would fail at compile time. You should definitely report that on the Connect site. (Note: there's no point reporting it on these forums - Connect is the proper place to report technical issues so that they can be escalated through the support and product teams).
