How to implement the multi-row editing feature in the ASPxGridView

We already have the E158 example showing how to implement a similar feature. The project below is a simplified version of the same functionality, which allows you to edit all rows on a current page at once. To implement this, I added the ASPxTextBox to the DataItemTemplate Container of several columns and bound these editors to the underlying data source. This will force the ASPxGridView to always display editors in these columns. So, the end-user can input values in these editors. After that click the PostModifications button to preserve the changes made. NOTE, this is done without switching the ASPxGridView to the EditMode and back.

To preserve the changes made, I saved editor values to the List<object> and then used these values by setting the UpdateParameters of the ASPxGridView's DataSource. Finally, to obtain editors and their values, I used the ASPxGridView.FindRowCellTemplateControl Method.
