Visual diff of 2 DataTables

Posted By:      Posted Date: October 02, 2010    Points: 0   Category :Windows Application

I wasn't sure of the best place to post this (Visual C# general or here) so hopefully I've chosen correctly :).

I would like to write an application that performs a visual diff of 2
DataTables. Let's call them source and destination. There are several
components to this that I would like to solicit opinions on.

I have written something that kind of works but I'm sure there are better
ways to do this. My application is a form that contains 2 DataGridViews, one tied to the source DataTable and the other tied to the destination DataTable.

My end goal is to have records that appear in destination but not in source show with a red background color, records that appear in source but not in destination show with a green background color and rows that have a difference in a field show up yellow (only the changed cell).

The user should then be able to select which source rows then want to propagate to the destination and which rows in the destination that should be deleted so that they match. Those changes will be applied by generating a .SQL file containing the necessary statements.

One important thing to note is that these DataTable objects will be populated from XML files. This application will not have access to the back-end database directly or at the very least it will only have access to one of them but never

Visual Studio 2010 Beta 2

This is a big deal. This isn't ".NET 3.6" - there are a lot of improvements of .NET 4, and it's not just "pile on a bunch of features so you get overwhelmed."

ASP 4 - Whirlwind Tour around .NET 4 (and Visual Studio 2010) Beta 1

There's a lot of stuff that's new and added in .NET 4, but not in that "overwhelming-I-need-to-relearn-everything" way. More in that, "oh, this is way easier/simpler now" way. Like, moving data around with ADO.NET DataServices is easy, binding with client templates is easy, there's F# if you need it, the "dynamic" keyword if you need it, Silverlight's already installed, oh, and the parallel stuff will freak you out, but in a good way.
