  Hey Guyz,
  
  Development: Visual C# .NET 2003
  
  I need to represent a Matrix of Data (ie. AZ x ZA Matrix (Columns named A to Z, Rows named Z to A) )
  
  I enter the required data into a DataTable (System.Data.DataTable) and then use it as the source for a DataGrid (System.Windows.Forms.DataGrid).
  
  During the construction of the DataTable I can assign the necessary Columns names, but I have no idea what to do about the Row names?
  
  
  Can you assign Row names to a DataTable?
  Can you assign Row names to a DataGrid?
  Is there any other Control that I can use to display Matrix type data?
  
  
  Your help will be greatly appreciated! :)

  Can you assign Row names to a DataTable?

  ScubaSteve

  Nope. A data table represents a table from a database. Rows aren't named. Using a field called 'Row Name' could do the trick though.
  

  Can you assign Row names to a DataGrid?

  ScubaSteve

  Not sure, I don't use data grids much.
  But the VS 2005 seems to have properties for row headers
  

  Is there any other Control that I can use to display Matrix type data?

  ScubaSteve

  You can manually populate the stuff yourself, and keep the data in your own structures
  E.g. ArrayLists and HashTables
  More work though, but that's what I'm accustomed to. I tend to do a lot of backend and complex game logic

  Thanks for the info Placebo :>
  
  I did consider the option of a "Row Name" field, but the problem is that the table has quite a lot of fields, thus as soon as you start scrolling to the right you loose the connection to the rows :( (if you know what I mean)
  
  Will try source some more info on this. maybe there is a custom "matrix view" control that i can use...

  If you could find a control that would 'freeze' the left-most column, you'd be set :)
  Good luck. Sorry I can't be more informative about database controls, I tend to do things the hard way without them.

  Just use two grids - and synchronise them!
  
  Hehehehe, entirely unoptimised and a heck of a lot of work :)
