I have posted a message today, But Now I found below issue, 

1、when I define a data schema in the ultragrid, there is two options to save it, which one should I use it?
2、I define a data schema in  the ultragrid, for example: there is three columns(ColA、ColB、ColC), the order
in the ultragrid is ColA、ColB、ColC, and their index in the ultagrid is  0、1、2;
then I use "Select ColA,ColB,ColC From Table1" to generate a datatable and set it to the ultragrid, But I find that the column order is not ColA、ColB、ColC,I use the way
in the other WinForm, the column order is right in some WinForm,but some is not. I don't know the reason?

Could  you give me some suggestion? Is it maybe caused some property?
