Search Hierarchy Modes

The tree grid supports different types of search mode through the searchHierarchyModeof e-searchsettings property.

The following are the types of search modes available in the tree grid.

Parent: This is the default search hierarchy mode in the tree grid. It displays a searched record with its parent records. If the searched records do not have any parent record, it displays only the searched record.

Child: Displays the searched record with its child record. If the searched records do not have any child record, it displays only the searched record.

Both: Displays the searched record with both its parent and child records. If the searched records do not have any parent and child records, it displays only the searched record.

None: Displays only the searched record.

The following code example shows how to set the searchHierarchyMode in the tree grid.

<div ej-treegrid id="treegrid" e-searchsettings="searchSettings" //…>
</div>

        .controller('TreeGridCtrl', function ($scope) {
            $scope.searchSettings = searchSettings;
            //…
