Please leave any options, comments, suggestions rant, etc. ------------------------------------------------ Update: I added support for animation and automatic close out thru the use of properties and custom Showing and Hiding methods.

Subclassing the .NET Treeview, Listbox and Combobox controls - Here are two completly functional sample Visual Basic .NET projects which demonstrate the rather simple but extremely powerful technique of subclassing the TreeView, ComboBox, or ListBox, such that you can store additional custom information behind (or inside) each individual Tree Node, Listbox Item or Combobox Item as you desire. There is no logical limit to the amount of additional information which can be stored alongside each individual node or item.

Lots of people still not using the very powerful feature on Indexed controls (or control array) of .net frame work. Which was very frequently used by vb6 people |-) In .net even it’s possible to put different type of controls together. To understand it more closely please have a look to my C-Sharp sample. I hope it would be quite easy to understand and simple to implement.. Using this you will really fill the more power in your code. Looking forward for your experts inputs for the improvements Thanks! My last Article on Control Array with VB.Net is also available here http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=1303&lngWId=10

This assembly uses the TreeView control to present a powerful alternative to the old VB6 dirList and driveList controls. Code was taken from the MS web site; it took me ages to find this and thought you might find it as useful as I did.

I've made a tiny dato field control. It has a textbox and a little button next to it. The little button pops up a calendar, so you can pick your date with the mouse. It works fine. But it's a little annoying that I have to show the popup form before I can move it. It gives a little flicker that way. It would be great if anyone could solve this.
