Here is an extensive article that helped me: http://aspnet.4guysfromrolla.com/articles/040502-1.aspx

I'm not sure exactly what part of the article your specific question falls into, but I am pretty sure it is in there somewhere.

>>>Hi.
>>>I have an 'Maintenance' page which is working fine to Add records.
>>>I also have a Search page which returns a Page with a DataGrid of selected records.
>>>I would like to be able to Click on a record in the dataGrid,and call the 'Maintenance ' page with the Primary key.
>>>Then in the Load of the Page, either enable the 'Add' or Modify button.

>>>My problem is I'm not sure how to add a column to the grid, so that when it is clicked, it calls the maintanace page with the Primary Key of the record.

>>>Any help appreciated
