Treeview Child Sort Order

Hi all!

Does anyone have a way to quickly sort the Treeview child nodes of a Parent, say, in alphanumeric order?

Example:

Parent 1 - State 
     |____Texas
     |____Alabama
     |____New York

Kind regards,
Jason

Hi Jason,  
 
Greetings from Syncfusion support. 
 
In TreeView component, we have sortOrder property. Using this property, you can sort the TreeView nodes in ascending and descending order based on your requirement. 
 
Please, refer the below code snippet. 
 
<SfTreeView @ref="tree" TValue="MailItem" SortOrder="SortOrder.Ascending"> 
    <TreeViewFieldsSettings TValue="MailItem" Id="Id" DataSource="@MyFolder" Text="FolderName" ParentID="ParentId" HasChildren="HasSubFolders" Expanded="Expanded"></TreeViewFieldsSettings> 
</SfTreeView> 
 
 
 
Please, refer to the below links to know more about the TreeView component. 
 
 
 
 
Please let us know, if you need any further assistance.

Is there a way to sort by a different property than the alphabetic content of the node?

Thanks

Hi BAx,  
 
Currently, we don’t have any direct property to sort the TreeView node based on a different property other than alphabetic content. To achieve your requirement, you need to manually sort the nodes based on your requirement and assign the sorted data to the TreeView dataSource. 
 
This will re-render the TreeView component with sorted data. 
 
Please let us know, if you need any further assistance.

Ok so if I do not define the SortOrder in the TreeView the items order will reflect exactly the order in which they are provided?

Hi BAx, 

The default value of SortOrder property is none which will update the TreeView node order based on the order of items in DataSource. As mentioned earlier, you can assign the manually sorted data as dataSource without assigning SortOrder property in your code.
