InfoPath Dev

Hello

I'm getting the data into a drop-down list from a web service. (Infopath 2003)

I need that drop-down to be sorted, and so far the only solution that i could find is to modify the DataObject

 Here is the code: http://pastebin.com/Yj947TkB

The problem with this is: when there are hundreds of items in the dropdown, infopath freezes. I'm guessing every time a 

                IXMLDOMNode spec = specs[i];
                spec.text = a[i];

is executed, the form is updated, and doing this hundreds of times is bad.

So, is there a way to stop the form during the FOR to auto-update, or is it another way i can access the drop-down and sort it's data?

Have a nice day.

Added

thisXDocument.View.DisableAutoUpdate();

at beginning and

thisXDocument.View.EnableAutoUpdate();

at the end and it doesn't work, form still freezes

Done.

 Added <xsl:sort select="." data-type="text" order="ascending" case-order="upper-first"/>  in the XSL file so no coding required

Tho i'm still curious about the coding part, how would be the right way on doing it, so if anyone knows please answer :)
