Since the roles and implementations of Data and View of SMART datagrid are strictly separated and loosely connected only through internal events, several grids can be connected to one data set naturally.
The grids connected to the same data set have their own Column Models and can display the same data differently. In addition, they can individually apply sorting, filtering, grouping and paging and have their own Focused Cell. And, the data, which has been updated in one grid, will be immediately reflected in the other grids, of course.
If you want to share the state of sorting and filtering, you can use Row Source. Please refer to Shared Row Source example.
Although Grid-1 and Grid-2 share Data Set, they are made up of different column models. And, since the filter is set in Quantity column of Grid-2, the row number of Grid-2 will be displayed less. However, if update or delete the row in one grid, it will be immediately reflected in the other grid.
