Hi,

We are using 2010.03. And for below layout (with 60 fields) moving columns programatically is very slow, however drag/drop is much faster.

Noticed that the the performance is much better when removing LabelTextWrapping="Wrap" field settings.

Can someone please let me know (a) why this setting is causing when calling Move and (b) what other options/settings that can posibly changed to improve the performance of column moving?

Thanks in advance.
