Pre-Select Checkbox in Tree Table based on JSON data

[suryakanta101]

Hello @mazdik

Can it be possible to Pre-Select Checkbox based on JSON received from service on DataTable.

ex: [
{
"id": "1",
"name": "ASMODIANS",
"isSelected" : true,
"data": {
*****

Something like below might possible by adding a new attribute to data transformer

[transformer = (node: TreeNode, level: number) => {
const data = {
expandable: true,
$$level: level,
$$checked: node.isSelected,
hasChildren: (node.children && node.children.length > 0)
};
How to add "$$checked" here to selection object ???

      this.dataTable.rows = this.prepareTreeData(data);
      this.dataTable.rows.forEach((x: Row) => {
        if (x.$$checked) {
          this.dataTable.selectRow(x.$$index);
        }
      });
