How to disable drags and drops within treegrid?

[alastairwalker]

I am trying out the example in http://www.jeasyui.com/extension/treegrid_dnd.php for d and d between the treegrid and datagrid.

The functionality I need must disable the d and d within the treegrid.

I want to restrict the functionality to:
a) select a row from the treegrid;
b) to only allow a drop on the datagrid.

How do I go about this?

I searched the posts, but could not locate how to do this.

Many thanks in anticipation..

To disable dropping nodes on the treegrid, please try the code below:

Code:

$('#tg').treegrid({
	onDragEnter: function(targetRow,sourceRow){
		var opts = $(this).treegrid('options');
		var tr = opts.finder.getTr(this, targetRow[opts.idField]);
		if (tr.attr('node-id')){
			return false;
		}
	}
})

Many thanks!

For the record, this is the script I had to actually use:

$(function(){$('#tg').treegrid({onDragEnter: function(targetRow,sourceRow)
   {
   var opts = $(this).treegrid('options');
   var tr = opts.finder.getTr(this, targetRow[opts.idField]);
   if (tr.attr('node-id')){return false;}
   }})
});

(Note: the parentheses were unbalanced.)
