有没有好的免费/廉价Delphi网格控件？

Question

I gave up on Delphi's DBGrid nearly a decade ago because it is simply no good. Since then, I have used Virtual TreeView which offers a lot of value but it has a few issues. Like the current state of development (eg None) and the fact that there is no good data-bound version. DevExpress's QuantumGrid is famous for the rich feature set but is really quite expensive. I reckon that its huge feature set is probably overkill for 95% of the general use cases for data-bound grid controls.

Does anyone know of a data-bound grid control that sports the following features:

1. Checkboxes for boolean fields. How obvious is that?
2. More effective way of dealing with editors, ie no need to click three or four times to get the pick list to show.
3. Has to be data-bound.
4. Modern-looking. Possibly using XP themes, but being skinnable is preferable.
5. Flexible owner-drawing. This is one of the great features of Virtual Treeview - you can literally replace any part of the cell drawing without upsetting the rest. Painting is done in a series of layers, and you opt to replace only the layers you need to modify.
6. Wrappable lines, or at least tooltips that pop up and show the content that has been truncated for display.

I seldom use editing within a grid control, so the editing features need not be fantastic.

Any good suggestions?

Answer 1

Virtual TreeView is very much alive and development is continuing. See its new home here: http://code.google.com/p/virtual-treeview/

Answer 2

NiceGrid

TSMDBGrid

If you are using Delphi 6 or 7 you can get free NextGrid component, if you don't, you can buy the full version with source code for very low price, it's fast and has nice looking grid.

Answer 3

Oooppppsss!

It's already added. Excuse-me.

You can see this , from Scalabium .
It's free and Sources included. See the images at link.

Regards.

Answer 4

I also had some problems with the pricing of the DevExress Quantumgrid. However, if you are a serious Delphi developer and make a living out of it, I think the DevExpress controls are well worth the investment. DevExp also seems to have picked up Delphi development once again.

Answer 5

I have had good luck with NextGrid.

It is extremely fast and Boki (the developer) gives very good support.

You could try ElTree that comes with the free SE Version of the LMD ElPack package: http://www.lmdinnovative.com/mfs/products/lmdelpack.php

It is described as:

ElTree is a fully customizable visual component, that can represent virtually any type data (both in hierarchical and list forms). It is excellent for exploring databases, directory structures, registries, or any other type of data that is built up like a tree. You don't need to use the combination of TTreeView and TListView anymore - TElTree gives you all their power. ElTree is also very useful for building multi-columned list boxes, radio groups and CheckLists. And it adds full Unicode support.

I've been using ElTree in my application for many years, both as as tree in one part of the program, and as a grid in several other parts. I took a look a while back at Virtual TreeView, but I saw no compelling reason to change.

LMD ElPack SE is designed for users, who are interested in the ElTree component only. I think it meets all your qualifications.

Its last supported IDE is Delphi 2006. If you need it for Delphi 2009, you would need to upgrade to one of their non-free packages.

Answer 7

If we'd been voting I'd say TSMDBGrid. İt is almost perfect. Just a few days ago I checked its source code to see how it uses the filter edit (to exploit it, of course).

It is free too.

Answer 8

我不确定你认为便宜的价格点，但我们在X-DBGrid上取得了很大的成功。

Answer 9

TMS Software have a data aware version of there TAdvStringGrid component.

You can download a trial and there are some sample applications for the TDBAdvGrid available.
