I have the following data representation displayed in a TreeList where there are two columns:  Name and Creation Date.  (Each Value entry is a child of the parent Item entry.)

Name - Creation Date

Item 1 - Jan 01, 2017

     Value 1 - Jan 11, 2017
     Value 3 - Jan 02, 2017
     Value 2 - Jan 01, 2017

Item 2 - Dec 20, 2016

     Value 2 - Dec 20, 2016
     Value 1 - Dec 17, 2016
     Value 3 - Dec 16, 2016

Item 3 - Nov 15, 2016

     Value 3 - Nov 25, 2016
     Value 1 - Nov 22, 2016 
     Value 2 - Nov 20, 2016

What do I need to do in order to sort by the Name value vs. the Creation Date so that it appears as follows:

Item 1 - Jan 01, 2017
     Value 1 - Jan 11, 2017
     Value 2 - Jan 01, 2017
     Value 3 - Jan 02, 2017

Item 2 - Dec 20, 2016
     Value 1 - Dec 17, 2016
     Value 2 - Dec 20, 2016
     Value 3 - Dec 16, 2016

Item 3 - Nov 15, 2016
     Value 1 - Nov 22, 2016 
     Value 2 - Nov 20, 2016
     Value 3 - Nov 25, 2016

No sort order is set in the TreeList markup; all the columns in the TreeList are sortable such that if I click the Name column header, the child rows are sorted appropriately.

Hello Matt,

We can apply the sort you describe by using the sort property of the Kendo UI DataSource; you can read more about it here.

I have prepared a sample in the Kendo UI Dojo to see how it could be done; take a look at it here. The relevant part:

sort: [
   { field: "HireDate", dir: "desc" }
]

Keep in mind that the sort object can be set to an array in order to set multiple sort parameters at the same time so you could sort by both name and date if necessary.

I hope this helps!
