Choice in Grid Control

I am working on a project in which I need to place a grid control frequently. May be sometimes I will be using a grid control 6 times on different tabs of a tab control on one form. which may put extra load on the form making the system slow. I need help in finding such a grid control which will occupy minimum space in memory. Also as I will be using dropdown on the grid so this grid must have the option of placing a combo box as its own feature. One other feature this grid must have is , the combo box must have the option of storing ID in some way as we may store ID using ItemData property in an ordinary combo box. PLZ help me finding such grid control.

Have you had a response yet?

Are your grids going to be bound controls?

Here are 3 suggestions:

Objective Grid - http://www.roguewave.com/
There's a new pro version that looks quite promising. I haven't work with this product extensively and only with MFC not VB, but from what I've seen, it's very fast and has a small footprint.

Protoview datatable - http://www.protoview.com/
Unbound mode rocks. Not very intuitive apis, but once you get familiar with the quirks, a pleasure to work with.

Sheridan datawidgets - http://www.shersoft.com/
Multi-threaded datagrid which gave us some headaches. Trying to remove all instances from an app as we speak. Haven't worked with it extensively either.

Try the VideoSoft FlexGrid control, it gives more functionality than most grids, but is very cheap. It has all the options you specifically requested. You can get it from http://www.videosoft.com
