Hi, 

I have a Kendo tree view with three levels. Please see the attached file MyTree.jpg.

I have a leaf node's with text value "CHINA".  I am not able to get the leaf node's parent node text. Please see the attached file ChromeOutput.jpg. 

Please advise why undefined is returned for below -

treeview.text(treeview.parent(treeview.findByText("CHINA")))

Regards, 
Manoj

Hello Manoj,

I tried reproducing this problem in the following Dojo snippet, to no avail. Can you please adjust it so that it shows the problem?

Hi Alex, 

Thanks. 

The problem is not simulating in the Dojo or Chrome console using the Dojo code. I am using razor view and C# to generate the tree. I am also attaching my tree view definition.

Can you please advise any other way to get the parent node's text ?

Regards,
Manoj

Hello Chanchal,

Remove the DataTextField line and the problem will be resolved.

The problem in this scenario is that the DataTextField instructs the text method that the text is stored in the "Text" field. This can be true if the tree was loaded via AJAX; however, the TreeView is rendered from the server, so the datasource uses the default, lowercase-t "text" field. So, the text method returns undefined.

Working sample is attached.
