Parameters
- order
- SortFlags value that specifies the sort direction and options.
- col
- Column to sort on.
Sorting works differently depending on whether the grid is bound to a data source or not.
In bound mode, the grid passes the sort request to the underlying data source object. In this case, the sort settings remain in effect as the grid data changes. Editing values in the sort column will cause the data source to re-sort the data, and grid will show the changes automatically. This is equivalent to setting the System.Data.DataView.Sort property on a System.Data.DataView object for example.
In unbound mode, the Sort method sorts the data that is currently stored in the grid. Changing the data after it has been sorted will not automatically update the sort.
When the grid is bound to a new data source, it inherits the sort settings currently applied to the new data source object. Because of this, calling Sort immediately before setting the DataSource property has no effect on the grid.
In unbound mode, the grid uses a stable sorting algorithm. This means that the sorting keeps the relative order of records when the sorting key is the same. For example, if you sort a list of files by name, then by extension, the list will still be sorted by name within each extension group.
The grid recognizes two types of row: regular rows which contain data, and node rows which are used to group data. The Sort method only sorts regular rows; it does not affect node rows at all. To sort nodes, use the GridTree.Sort method in the C1FlexGridBase.Tree property or the Node.Sort method in the Node class.
