Alex,

There isn't really anything magical about any of the .NET controls. Fundamentally, the container controls all work the same way (DataGrid, DataList, Repeater).

You can use a checkbox without an immediate post-back. Before re-binding the list, in the Submit button's click handler, iterate through the rows of the list control (DataGridItem, DataListItem, RepeaterItem) checking the checkbox in each row and updating the datasource as needed.

To make this easier, be sure to include the PK of the datasource in a column as a non-visible label and get the value from it at the same time that you get the value of the checkbox.
