Select alignments is very very slow (API)

[joantopo]

I have checked both methods:

http://forums.autodesk.com/t5/AutoCAD-Civil-3D-Customization/select-alignment-via-ObjectId/td-p/4517...

But with both cases ribbon of alignment appears very fast but selection alingment in graphic is very very slow...

What happens?

I don´t understand why if I do select and zoom entity, program takes few time to select alingment  :

 Autodesk.AutoCAD.Internal.Utils.SelectObjects(arrayId);
         Autodesk.AutoCAD.Internal.Utils.ZoomObjects(false);
          System.Windows.Forms.Application.UseWaitCursor = false;

but if I only select alignment, it takes a lot of time.

Solved, the last line should be:

 Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor.UpdateScreen();

 or with commandFlag redraw.
