I am not able to mark checkboxes in a Treegrid using SelectCheckboxes or SelectRows

[Daniel]

Hi, currently I'm having problems with the TreeGrid trying to mark checkboxes using SelectCheckboxes or SelectRows, the checkboxes have a hierarchy, I need the checkboxes to be marked based on a condition, I attached a project with the code that I'm using, anyways I'm also adding the code here

@page "/"

@using Syncfusion.Blazor.TreeGrid;

<SfTreeGrid @ref="@TreeGrid" DataSource="@BusinessObjectCollection" IdMapping="TaskId" AllowSelection="true" ParentIdMapping="ParentId" TreeColumnIndex="0" AutoCheckHierarchy>

    <TreeGridColumns>

        <TreeGridColumn ShowCheckbox Width="80">TreeGridColumn>

        <TreeGridColumn Field="TaskId" HeaderText="Task ID" Width="80" TextAlign="Syncfusion.Blazor.Grids.TextAlign.Right">TreeGridColumn>

        <TreeGridColumn Field="TaskName" HeaderText="Task Name" Width="160">TreeGridColumn>
