  I did something mildly similar before. Rather than write ASP.Net code to summarize data, I used T-SQL and temporary tables. One grid that represents the detail of the data, a second one that summarizes, in this case money, values such as Month-To-Date and Year-To-Date. Both are temporary tables returned by the stored procedure but who's life-span is the execution of the procedure. It's quick and clean, and all the logic and work is back-ended to the server. The ASP.Net code is just a few lines, amounting to assigning the result set from the procedure to the grid.

    Hi, You are right and there are several other methods to perform the task done in the artcile. But you missed the point. My focus was just to do some kind of datagrid related task encapsulated inside a custom column so that it can be reuse in every other applications. The task can range from formatting to other repeated complex operations in a particular application. I hope i cleared the point.

  System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'Custom:CustomColumn' is of type 'Custom.CustomColumn'. "Custom"=My ClassLibraryName "CustomClass"= my class name
