Gridview not returning data in event

[MarkAurit]

I have a gridview that some boundfield and buttonfield controls. I have a
data element I
1. want to use when the button is clicked for a given row, but
2. dont want it visibly displayed in the gridview
so I created a boundfield with visible=false as the first column (something
I did in the datagrid).
In my RowCommand event I do some processing using the online docs as a
template. The problem is that when I reference the boundfield as
visible=false, no data comes back. If I set it to visible=true, data does
come back. The problem is that I dont want it to show up in the grid, but I
want access to the data.
Is this possible using the boundfield, but is there another alternative in
the gridview?
Thanks, Mark

If the data is a primary key then use the DataKeys of the GridView otherwise
use cssClass to specify a descriptor where the .display='none' ;

sound's like the same question I just answered, so I'll
repost my answer here:

Ok, I'm working from memory here so my facts might be a
little off.

Anyhoo - select your datagrid and press f4, find the
property 'DataKeyNames'

Lets say you want to retrieve CustomerID from the database
but don't want to display it in the grid.

Add 'CustomerID' (without quotes) to the DataKeyNames
collection, repeat this for your other fields.

You can retrieve the data with code something like this

GridView1.DataK eys(RowIndex).I tem("CustomerID ")

Thank you Phillip. Am I correct that this lets you save only 1 column's
value? In my situation the pk is made up of >1 column, so I concatenated
them and made that the DataKey.

Hi Mark,

This property takes a comma-separated list of field names and then you would
refer to each key by its index, e.g. GridView1.Selec tedDataKey.Valu es[0] and
GridView1.Selec tedDataKey.Valu es[1] and so on.
