How is sort order handled?

[Armand De Lange]

Hi

I want to sort nodes by a separate integer sort order field in die database, how can it be done?

What data field is used to handle sort in the treeview object?

THX

Hi Armand, 

 

Thanks for contacting Syncfusion support. 

 

 

We have checked your query (“How is sort order handled”). You can achieve your requirement by using sortSettings API in ejTreeView.  you can sort the treenodes node by its node text Please refer the below code snippet. 

 

 

$("#treeView").ejTreeView( 

{ 

    fields: { id: "id", parentId: "pid", text: "name", hasChild: "hasChild", dataSource: localData, expanded: "expanded" }, sortSettings: { 

        allowSorting: true, 

        sortOrder: ej.sortOrder.Ascending 

    } 

} 

); 

 

To achieve this with your custom field, you should map the custom field as a node Text. 

 

For your convenience, we have attached the sample below,
