So how does everyone hide the primary key in a gridview with a datasource to
a table, let's say.  If you don't display it, then you can't update the
records.  Users don't want to see this field, particularly if it's a guid.
Example:

I'm trying to get the value of a cell in my DataGrid_UpdateColumn()
event handler.  I have a datagrid with 4 columns:
1 - Name, 2 - Description, 3- Button Column (Edit,Update,Cancel), 4-
Primary Key Value for row

In the following article, it says to have a button ina  gridview, you need
to capture the ItemCommand event.  Well, there is no ItemCommand event in
the gridview.  So I use the RowCommand.  The Article says to use the
e.item.itemindex to determine the row that was selected, well ...

I have tried to set a gridview column to have a dataformatstring of {0:c2},
{0:c},{0:d2, {0:d}, none of which work, my values are still displaying as
19.0000.  I want it to be 19.00 like any normal currency.  Thank you for
your help.
