Below is a bit of code which sets up drag and drop in a treeview. This is handy for if you have a list of items that can be sorted by the user.

Here is a bit of code to demonstrate how to do this. First create a new Windows executable project. Drop a TreeView component on the form, and let's name it 'myTree' for this demonstration. Go ahead and populate it with some dummy data; enough data to see the dragging and dropping in action. You will need a variable global to the form's scope.

private TreeNode sourceNode;

This is used to track the item we are dragging in our TreeView. Then define the event handlers listed below.

Essentially, lets your users click a whole line of checkboxes by clicking the first and dragging down the line.

This is a crop-in script. That is to say, include it on your page, and you need do nothing else. Even primitive event handlers (element.onchange, for example) are supported, with no action on your part.

A demo of it in action is on my hosting:

This is the jQuery-compatible version. The libless version will be up soon.

This is the libless version; that is to say, it is independent of and doesn't interfere with any Javascript libraries, such as jQuery, Prototype, MooTools, etc.
