About datagrid column control

[Michael Yip]

Dear all :

I have some problem about databind, in design mode, I have create datagrid
with 4 columns. Menawhile , I have create the datatable with 8 columns
If I bind this datatable to datagrid during in RunTime. DataGrid will change
from 4 to 8 columns

How to avoid it , as I want to fix the column to 4 and don't want amend
datatable to fit with datagrid

Any idea ?

Thanks

Michael
