Hi Team,



I am dragging items from grid to tree and using dhtmlx_extdrag.js

I am allowing drag only from grid.I don’t want to allow drag from tree.

When I drag from tree I am getting following error,



this._checkMSelectionLogic is not a function

[Break on this error] function dhx_ext_check(sid,tid,sgrid,tgrid){if (sgrid.mytype==“tree”)var nm=“id”…





My code is,



tree.enableDragAndDrop(true);

tree.attachEvent(“onDragIn”,onTreeDragIn);

tree.attachEvent(“onDrag”,onTreeDrag);

tree.attachEvent(“onBeforeDrag”,function(){return false;});





function onTreeDragIn(sid,tree_node_id){

if(condition)

return dhx_allow_drag();

return dhx_deny_drop();

}



function onTreeDrag(row_id,target_id){

…

logic

…

}



Please suggest any solution to remove this error and not allow drag on Tree.



Thanks,

Agile

Which version of dhtmlxtree|dthmlxgrid are you using? The problem may occur if you are mixing files from pro and standard editions.
