Checking by linking child nodes in CheckBar

This is an example where the parent node is also checked when all child nodes are checked. We processed the check by adding a check action in the onItemChecked() event that occurs when the check bar is checked.

function checkNode(grid, dataRow, checked) {
     var provider = grid.getDataSource();
 
     //Check parent node after checking sibling nodes
     checkSiblingNode(grid, dataRow, checked);
 
     //Check child node
     var desRows = provider.getDescendants(dataRow);
     if (desRows) {
         grid.checkRows(desRows, checked, false);
     }
};
 
function checkSiblingNode(grid, dataRow, checked) {
     console.log("start-rowId2 checkedValue: " + grid.isCheckedRow(2));
     var provider = grid.getDataSource();
     //parent node
     var parent = provider.getParent(dataRow);
     //Sibling nodes
     var sibling = parent == -1 ? provider.getChildren() : provider.getChildren(parent);
     console.log(sibling);
     var index = sibling.indexOf(dataRow);
     //Exclude yourself
     if (index !== -1) sibling.splice(index, 1);
 
     if (checked) {
         for (var i in sibling) {
             var value = grid.isCheckedRow(sibling[i]);
 
             if (checked != value) {
                 checked = false;
                 break;
             }
         }
     } else {
         checked = false;
     }
 
     if (parent > -1) grid.checkRow(parent, checked, false, false);
     //Control V display in checkBar.head area
     if (parent == -1) grid.setAllCheck(checked, false);
     if (parent > -1) checkSiblingNode(grid, parent, checked);
}
 
 
treeView.onItemChecked = function (grid, itemIndex, checked) {
   var dataRow = grid.getDataRow(itemIndex);
   checkNode(grid, dataRow, checked);
};
