Hi,

We are currently using an old kendo version - 2014.2.716 TreeView control and kendo.data.HierarchicalDataSource. We are making extensive use of data bound and change event on the datasource. When attempting to upgrade we are noticing that the behavior of the change event seems to be different in the latest kendo versions compared to the old version. For example the chan,ge event seems to now be generated for each of the parent nodes of the child node. Is there any documentation describing the changes from the old version and the event behavior in the new kendo version.

 

Thanks in advance..

Hi Michael,

No such changes in the datasource's behavior have been documented. Here's a link to the Hierarchical datasource change event documentation. Could you demonstrate the difference you see between version 2014.2.716 and 2017.1.223 with regard to the conditions under which the event fires? Here's a sample dojo in which we log to the console every time the event fires (for example when expanding a node). At my end I do not see any different behavior when changing the loaded Kendo UI files version from the older one to the latest official.
