Selecting rows and groups in the Server-Side Row Model is supported. Configure the selection
grid option as described in Row selection. Some SSRM-specific considerations are detailed below.
Server-Side Row Selection requires Row IDs to be supplied to grid.
Filters and Selection
The selected rows are preserved when the grid is sorted or filtered and are displayed as selected when scrolled into view. Select a row, apply a column filter so that the selected row is in the filter results and it will appear as selected in the filter results. If a selected row doesn’t match the applied filter, it will still be selected when the filter is removed.
Selecting All Rows
When using SSRM, the 'filtered'
or 'currentPage'
settings for rowSelection.selectAll
are considered invalid. The grid will behave as though rowSelection.selectAll = 'all'
, which is the default value. The example below demonstrates this.
When using header checkbox selection with the server-side row model, you should not use the api functions getSelectedNodes()
or getSelectedRows()
. See the API Reference section below for suggested alternatives.
Group Selection
When using group selection with the server-side row model, you should not use the api functions getSelectedNodes()
or getSelectedRows()
. See the API Reference section below for suggested alternatives.
Transactions
When adding a new row via transaction, the new row will be treated as if it conforms to the parents selection. Therefore, if the parent row was selected the new row will be treated as selected upon creation. For indeterminate groups, this will follow the last non-indeterminate state. Note the following:
- When clicking the
Add new Aggressive
button, the new row is unselected - After selecting the
Aggressive
group, new rows created by theAdd new Aggressive
button will be selected. - After toggling one of the child rows of the
Aggressive
group, new rows follow the group's previous selection state.
API Reference
The following API functions exist for the Server-Side Row Model when using Row Selection. These can be used to get the currently selected rows and nodes if all of the selected rows have been loaded by the grid. These cannot be used while using rowSelection.groupSelects
is 'descendants'
or 'filteredDescendants'
, or when any select all functionality is required.
Returns an unsorted list of selected nodes.
Getting the underlying node (rather than the data) is useful when working with tree / aggregated data,
as the node can be traversed. |
Returns an unsorted list of selected rows (i.e. row data that you provided). |
When using selection where all selected rows may not have been loaded, it is instead advised to use api.getServerSideSelectionState
and api.setServerSideSelectionState
, as these functions can be used to identify selected rows without having ever loaded the rows.
Returns an object containing rules matching the selected rows in the SSRM.
If rowSelection.groupSelects is 'self' the returned object will be flat, and will conform to IServerSideSelectionState .
If rowSelection.groupSelects is 'descendants' or 'filteredDescendants' the returned object will be hierarchical, and will conform to IServerSideGroupSelectionState . |
Set the rules matching the selected rows in the SSRM.
If rowSelection.groupSelects is 'self' the param will be flat, and should conform to IServerSideSelectionState .
If rowSelection.groupSelects is 'descendants' or 'filteredDescendants' the param will be hierarchical, and should conform to IServerSideGroupSelectionState . |
Selection API
The below snippet demonstrates how to set all nodes as selected, except for the row which has the ID group-country-year-United States
, and the row with the ID group-country-year-United States2004
.
gridApi.setServerSideSelectionState({
selectAll: true,
toggledNodes: ['group-country-year-United States', 'group-country-year-United States2004'],
});
In the example below, note the following;
- The above snippet has been included inside of the
firstDataRendered
callback, which sets the initial selection state. - The
Save Selection
button has been configured to store the result ofapi.getServerSideSelectionState()
, it also logs the saved state to the console when clicked. - The
Load Selection
button can subsequently re-apply the previously saved selection rules usingapi.setServerSideSelectionState(state)
.
Group Selection API
The below snippet demonstrates how to set all nodes as selected, except in the case of the "United States" group, whose only selected child is the row with the ID group-country-year-United States2004
.
params.gridApi.setServerSideSelectionState({
// this root level config can be used to determine a global select-all
selectAllChildren: true,
// all of the top level group nodes which do not conform with the select all value will have an entry here
// including indeterminate nodes
toggledNodes: [{
// as this is a group node with toggledNodes, this node will be marked as indeterminate
nodeId: 'group-country-year-United States',
// selectAllChildren can be used to determine whether this groups children are all selected
selectAllChildren: false,
toggledNodes: [{
// this group node has no toggledNodes, and so it will respect its own `selectAllChildren` property along
// with its descendants.
nodeId: 'group-country-year-United States2004',
selectAllChildren: true,
}],
}],
});
The state being used here conforms to IServerSideGroupSelectionState
, not IServerSideSelectionState
. Invalid states will be ignored.
In the example below, note the following;
- The above snippet has been included inside of the
firstDataRendered
callback, which sets the initial selection state. - The
Save Selection
button has been configured to store the result ofapi.getServerSideSelectionState()
, it also logs the saved state to the console when clicked. - The
Load Selection
button can subsequently re-apply the previously saved selection rules usingapi.setServerSideSelectionState(state)
.
Tree Data
Row selection is also supported when using tree data. See this documented on the SSRM Tree Data page.
