Hi Team,
I am using dhtmlx_extdrag.js to drag items from grid to tree.When I drag items from grid to tree it is showing style as 2 messages with allowed and not allowed images.I want to show not allowed on certain tree nodes.How to do that.I tried to modify the dhtmlx_extdrag.js but not got it working .Please suggest any solution.
using this reference sample.
dhtmlx.com/docs/products/docsExp … ?type=smpl
Tried to modify following function from dhtmlx_extdrag.js , but not got working…
function dhx_ext_check(sid,tid,sgrid,tgrid){
if (sgrid.mytype==“tree”)
{ alert(“tree”); var nm=“id”;}
else
{ var nm=“idd”;}
var sid=new Array();
for(var i=0;i<sgrid._dragged.length;i++)
sid[sid.length]=sgrid._dragged[i][nm];
if ((!this._onDrInFuncA)||(this._onDrInFuncA(sid,tid,sgrid,tgrid)))
return dhx_allow_drag();
return dhx_deny_drop()
};
Thanks,

You can use
tree._onDrInFuncA=function(sid,tid){
if (some_check(sid,tid)) return false; //deny
return true; //allow
});
where some_check - function wich will define allow|deny rules
