Business object data binding

Hello All,

I am binding a custom business object the gridview control.

When I bind a datatable to the gridview control, the columns are
displayed in the same order as the select statement used to populate
the datatable.

When I bind a custom business object to the gridview control, the
column order is not the same as the order in which the business object
properties are declared and I need to modify the columns collection.

Could someone briefly explain why this occurs ??


Thanks in advance!
