Hi Nathan,
Thank you for contacting Syncfusion support.
In TreeNavigator Control, Item Height is specified based on its Header height. So it is possible for an user to customize its header height based on that.
Please refer the following Code snippet.
Code Snippet [C#]:
//To set the Height this.treeNavigator1.Header.Height = this.treeNavigator1.Header.Height + 50; |
Screenshot
Figure: Items Height Changed.
We have also prepared the sample for your reference. It can be downloaded from the following Link.
Kindly check with above solution and let us know if it is helpful.
