Local Data in Angular TreeGrid component

29 Nov 2022 / 4 minutes to read

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.

  • Hierarchical Datasource binding
  • Self-Referential Data binding (Flat Data)

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, DataManager uses JsonAdaptor for local data-binding.

Hierarchy data source 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.

Self-Referential data binding (Flat data)

TreeGrid is rendered from Self-Referential data structures by providing two fields, ID field and parent ID field.

  • ID Field: This field contains unique values used to identify nodes. Its name is assigned to the idMapping property.
  • Parent ID Field: This field contains values that indicate parent nodes. Its name is assigned to the parentIdMapping property.

Refresh the data source

Add or delete the data source through an external button. To reflect the data source changes in the tree grid, you need to invoke the refresh method.

Please follow the below steps to refresh the tree grid after changing the data source:

Step 1:

Add or delete the datasource record by using the following code:

Copied to clipboard
this.treegrid.dataSource.unshift(data); // Add a new record.

this.treegrid.dataSource.splice(selectedRow, 1); // Delete a record.

Step 2:

Refresh the tree grid after changing the datasource by using the refresh method.

Copied to clipboard
this.treegrid.refresh(); // Refresh the tree grid.
