Tree selectItem Posts

Hi,

I have 2 jqxTree.

Tree1 –> id = “tree1”

Tree2 –> id = “tree2”

When I select an item from “Tree1” I need to show a “Tree2” item selected in “select” event of “Tree1”.

In “select” event of “Tree1” i use “$(“#tree2”).jqxTree(‘selectItem’, $(“#Tree2itemID”)[0]);” But it didn’t work.

Can you help me ? Thank you.

                        </ul>
                    </li>
                </ul>
            </div>
                  </div>
        </div>
    </div>
</body>
</html>

In the ‘select’ event of jqxTree we call the ‘selectitem’ method of jqxTree2 and select an item with id=Calendar. You can use the same approach for selecting other items.

Hi Mariya,
Thank you for your example. I looked at it. The only difference is my trees are json tree. I forgot talking about it.

I want to do it in json tree but i couldn’t. Can you provide an example me about json tree or can you give me an advice ?

Here is my tree codes;

treeObjects = ({

“id” : ID,
“value”: VALUE,
“label” : NAME
}, …

);

var source =
{
datatype: “json”,
datafields: [
{ name: ‘id’ },
{ name: ‘value’},
{ name: ‘label’ },
{ name: ‘items’ }
],
id: ‘id’,
label: ‘label’,
value: ‘value’,
items: ‘items’,
localdata: treeObjects
};

var dataAdapter = new $.jqx.dataAdapter(source);

dataAdapter.dataBind();

var records = dataAdapter.getRecordsHierarchy(‘id’, ‘parentid’, ‘items’, [{ name: ‘label’, map: ‘label’}]);

$(‘#idDivTree’).jqxTree({ source: records, height: ‘300px’, width: ‘300px’});

Thank you..
