Hi,
when i am setting drag text dynamically using rowToDragElement API in Treegrid, it throws below js error message but Dynamic Drag text was displayed correctly. Please advice to avoid js error msg being displayed

JS Error Message:

Line: 7
Char: 364
Code: 0
URI: http:// localhost:8080/bb_dev1/view/js/grid/dhtmlx_extdrag.js

Code used:

grid.rowToDragElement=function(id){
//any custom logic here
var count=0;
var selectedId = grid.getSelectedRowId();
if(selectedId!=null){
if(selectedId.indexOf(",") > -1)
{
var arr=selectedId.split(",");
count=arr.length;
}
else
count=1;
}
var text = count + " item(s) moving!!";
return text;
}

Hi sematik,
Please find attached demo zip file. for your information, we had modified dhtmlxgrid js for multiselection by single-click . Please suggest for the solution, Thank you

steps to recreate:
1)open index.html in browser
2) select row no 2 and 3 by single click / ctrl click
3) drag the selected rows

upd: demo has been removed, as it contains the js files from the PRO version of dhtmlx

In case of customizing the the drag overlook behavior using the methods or events, please, try not to use the dhtmlx_extdrag.js as it creates it’s own customization, which may conflict with your custom.
