asp.net gridview user control with subtotals

C# VS2005 [login to view URL] ONLY I'd like a user control that implements a gridview with subtotals and totoals for each numberic column, given a DataTable with unknown columns: DataTable source int initial_sort_column ColumnSpecs[] = { {"column1", "Users", "{0:c}", false, true}, {"column2", "Users", "{0:0.00}", true, true} } Columnspecs = Name of datatable column to use HeadingText String ({0:c} etc) boolean Display Average boolean Display Total The user control will have to dynamically build the grid by adding grid template fields Without any columsn specified it will simply output all columns and default to the DataTable heading name for the title. If the Type of the columns is a numberic, it will default to displaying averages and totals in the footer. As well I'd like client side sorting using: <[login to view URL]> Remember the number of columns is unknown. Please use an XML data source for now. The idea is that I can reuse this control with any type of data by feeding it a datatable. Note that inheriting the gridview class is also possible. ## Deliverables VS 2005 c# project with the use control and an example page.
