The TreeGrid uses DataManager, which supports both RESTful JSON data services binding and local JavaScript object array binding. The dataSource property can be assigned either with the instance of DataManager or JavaScript object array collection.
It supports two kinds of data binding method:
In Local Data binding, data source for rendering the TreeGrid control is retrieved from the same application locally.
Two types of Data binding are possible with the TreeGrid control.
To bind local data to the treegrid, you can assign a JavaScript object array to the dataSource property. The local data source can also be provided as an instance of the DataManager.
By default,
DataManagerusesJsonAdaptorfor local data-binding.
The childMapping property is used to map the child records in hierarchy data source.
The following code example shows you how to bind the hierarchical local data into the TreeGrid control.

});Herewith we have provided list of reserved properties and the purpose used in TreeGrid. We recommend to avoid these reserved properties for Internal purpose(To get rid of conflicts).
| Reserved keywords | Purpose |
|---|---|
| childRecords | Specifies the childRecords of a parentData |
| hasChildRecords | Specifies whether the record contains child records |
| hasFilteredChildRecords | Specifies whether the record contains filtered child records |
| expanded | Specifies whether the child records are expanded |
| parentItem | Specifies the parentItem of childRecords |
| index | Specifies the index of current record |
| level | Specifies the hierarchy level of record |
| filterLevel | Specifies the hierarchy level of filtered record |
| parentIdMapping | Specifies the parentID |
| uniqueID | Specifies the unique ID of a record |
| parentUniqueID | Specifies the parent Unique ID of a record |
| checkboxState | Specifies the checkbox state of a record |
| isSummaryRow | Specifies the summary of a record |
| taskData | Specifies the main data |
| primaryParent | Specifies the Primary data |
To bind remote data to TreeGrid component, assign service data as an instance of DataManager to the dataSource property. To interact with remote data source, provide the endpoint url and define the hasChildMapping property of treegrid.
The hasChildMapping property maps the field name in data source, that denotes whether current record holds any child records. This is useful internally to show expand icon while binding child data on demand.
The TreeGrid provides Load on Demand support for rendering remote data. The Load on demand is considered in TreeGrid for the following actions.
When load on demand is enabled, all the root nodes are rendered in collapsed state at initial load.
When load on demand support is enabled in TreeGrid with paging, the current or active page’s root node alone will be rendered in collapsed state. On expanding the root node, the child nodes will be loaded from the remote server.
When a root node is expanded, its child nodes are rendered and are cached locally, such that on consecutive expand/collapse actions on root node, the child nodes are loaded from the cache instead from the remote server.
Similarly, if the user navigates to a new page, the root nodes of that specific page, will be rendered with request to the remote server.
Remote Data Binding supports only Self-Referential Data and by default the
pageSizeModefor Remote Data isRootmode. i.e only root node’s count will be shown in pager while using Remote Data

});By default,
DataManagerusesODataAdaptorfor remote data-binding. Based on the RESTful web services, set the corresponding adaptor to DataManager. Referherefor more details. Filtering and searching server-side data operations are not supported in load on demand
While binding remote data to Tree Grid component, by default Tree Grid renders parent rows in collapsed state. Tree Grid provides option to load the child records also during the initial rendering itself for remote data binding by setting loadChildOnDemand as true.
When loadChildOnDemand is enabled parent records are rendered in expanded state.
The following code example describes the behavior of the loadChildOnDemand feature of Tree Grid.

</script>Also while using loadChildOnDemand we need to handle the child records on server end and it is applicable to CRUD operations also.
The following code example describes handling of child records at server end.
public ActionResult UrlDatasource(DataManagerRequest dm)
{
if (TreeData.tree.Count == 0)
TreeData.GetTree();
IEnumerable DataSource = TreeData.tree;
DataOperations operation = new DataOperations();
if (dm.Where != null && dm.Where.Count > 0)
{
DataSource = operation.PerformFiltering(DataSource, dm.Where, "and"); //perform filtering
}
if (dm.Sorted != null && dm.Sorted.Count > 0)
{
DataSource = operation.PerformSorting(DataSource, dm.Sorted); //perform sorting
}
var count = DataSource.ToList<TreeData>().Count();
if (dm.Skip != 0)
{
DataSource = operation.PerformSkip(DataSource, dm.Skip); //Paging
}
if (dm.Take != 0)
{
DataSource = operation.PerformTake(DataSource, dm.Take);
}
if (dm.Where != null)
{
DataSource = CollectChildRecords(DataSource, dm); // method to collect child records
}
return dm.RequiresCounts ? Json(new { result = DataSource, count = count }) : Json(DataSource);
}
public IEnumerable CollectChildRecords(IEnumerable datasource, DataManagerRequest dm)
{
DataOperations operation = new DataOperations();
IEnumerable DataSource = TreeData.tree; // use the total DataSource here
string IdMapping = "TaskID"; // define your IdMapping field name here
int[] TaskIds = new int[0];
foreach (var rec in datasource)
{
int taskid = (int)rec.GetType().GetProperty(IdMapping).GetValue(rec);
TaskIds = TaskIds.Concat(new int[] { taskid }).ToArray(); //get the Parentrecord Ids based on IdMapping Field
}
IEnumerable ChildRecords = null;
foreach (int id in TaskIds)
{
dm.Where[0].value = id;
IEnumerable records = operation.PerformFiltering(DataSource, dm.Where, dm.Where[0].Operator); //perform filtering to collect the childrecords based on Ids
ChildRecords = ChildRecords == null || (ChildRecords.AsQueryable().Count() == 0) ? records : ((IEnumerable<object>)ChildRecords).Concat((IEnumerable<object>)records); //concate the childrecords with dataSource
}
if (ChildRecords != null)
{
ChildRecords = CollectChildRecords(ChildRecords, dm); // repeat the operation for inner level child
if (dm.Sorted != null && dm.Sorted.Count > 0) // perform Sorting
{
ChildRecords = operation.PerformSorting(ChildRecords, dm.Sorted);
}
datasource = ((IEnumerable<object>)datasource).Concat((IEnumerable<object>)ChildRecords); //concate the childrecords with dataSource
}
return datasource;
}On remote data binding, all treegrid actions such as paging, loading child on-demand, will be processed on server-side. To avoid postback, set the treegrid to load all data on initialization and make the actions process in client-side. To enable this behavior, use the offline property of DataManager.

});During server interaction from the treegrid, some server-side exceptions may occur, and you can acquire those error messages or exception details
in client-side using the actionFailure event.
The argument passed to the actionFailure event contains the error details returned from the server.

});The
actionFailureevent will be triggered not only for the server errors, but also when there is an exception while processing the treegrid actions.
You can use TreeGrid dataSource property to bind the data source to TreeGrid from external Ajax request. In the below code we have fetched the data source from the server with the help of Ajax request and provided that to dataSource property by using onSuccess event of the Ajax.
