I load a listview by setting the datasource to a datatable. The datatable is already sorted on a column, call it ColumnA.
When the listview first shows the data, there are no column headings clicked for sorting. So if the user clicks on the first column header, it will add the sort graphic for ascending on that column, but will just do nothing as far as the user sees, because it loaded that data already sorted on ColumnA.
1) How do I programmatically set the ColumnA column to show sorted?
2) Do I have to physically sort the table when I do this, as that is an extra step, and the data is sorted to begin with?
3) Is there a way for the user to select multiple columns, and sort on multiple columns?
4) Is there any kind of functionality where the user can double click between columns to size the column to the best fit?
