Researching drag-and-drop with Infragistics 9.1.  Installed version is 9.1.20091.1015.

I have a UltraWebGrid bound to some data.

In script I have...  Which I got from the online documentation.

function pageLoad() {
            //alert('page load');
            var ddb = new $IG.DragDropBehavior();
            var grid = igtbl_getGridById("UltraWebGrid1");
            var rows = grid.Rows;
            var count = rows.length;

            // Set the source
            for (var i = 0; i < count; i++) {
                // Get the HTML rows of WebGrid
                var row = rows.getRow(i).Element;
                ddb.addSourceElement(row);
            }

           // Set the target (a simple static UltraWebTree)
            var tree = igtree_getTreeById("UltraWebTree1");
            var treeNodes = tree.getNodes();

            for (var i = 0; i < treeNodes.length; i++) {
                var node = treeNodes[i];
                //If the current nodes text is equivalent to the folder name and is not the selected node
                if (node.getText().toUpperCase() == 'INBOX') {
                    ddb.addTargetElement(node.Element, true);
                }
                                   
        }

In I.E.  this makes all rows in the grid, draggable.  And, when the tree node is "INBOX" it makes it a drop target.  I really don't need anything more than this.  I only need to simulate visually, the drag-and-drop, I don't need to actually move the element.

In IE, the code above works.  In Firefox, it messes with the grid.  The multi-select (or single-select) no longer works in the grid???

What am I doing wrong?
