We do supply full samples with the product.  You can take a look at the Windows Forms Feature Browser.  In there under the Navigation section you will see several tree examples, many with multiple columns.  Based on your description thus far, you may want to take a look at the outlookexpress view style.  I attached a screenshot of the samples.

Thanks Sung Kim for your reply. Do you have any working example similar to this, where tree and its olumn view is used?

I assume that each of those "types" are independant.  If so, you will probably have to use multiple trees.  One for each type.

If they are linked, as in expanding one expands another, you can probably use the tree and its column view.
