I am not able to use the function onBeforeDrag in dhtmlxtree in my application. I am using standard version of dhtmlx. Please help do I need to include additional files.
Do yo use the latest tree version ?
onBeforeDrag is included into standard dhtmlxtree.js. So, you don’t need to include additional files.
I am using standard v2.0. onBeforDrag is available in v2?
Please, download the latest version 2.1
