Can DropGrid be configured to something like this effect:
1. There is an edit area, just like a regular edit, it display the Format'ted text as was before the edit start.
2. When user enters some text, it has some mechanism to allow Libary user's program to update/filter data to be displayed as candidates of choice accordingly, or at least it can hide currently populated rows that don't match user input.

This is not possible in current version. But you seem not to be first who would like to have possibility to edit text. I'll think about it.

3. Even better, the dropdown is polymorphic. When there are too many candiates, it may be easier to put in a TreeView, and when user input has filtered out but a limited number, a list may make more sense.

GridCtrl which is used to display the drop list doesn't support tree view (this is something I also wanted to implement long time ago)

By the way, the DropGrid example included with U++ package is very impressive. I particularly like the capability to set display columns and value columns (you can choose to hide the actual value column, eg, ID make a lot of sense to database but means little to end user.

I'm glad you like the DropGrid Smile

Unfortunately it uses a button to trigger dropdown. A user should be able to click the little triangle to the right or use certain key combination to show the popdown list.

I don't understand. What's wrong with trigger button? I guess you miss automatic list showing when user starts typing?

I'm working right now on the second version of my application which uses DropGrid and GridCtrl a lot and maybe I will be able to implement some of your features (especially point 1)
