DataGrid ASP.NET 2.0 C#

Hi,

I display a list of users (my SELECT contains the name and the ID of the
users) in a DataGrid.

The users display fine (single column).
On the SelectedIndexChanged event, I want to retreive the user ID.

Is there a way to attach the user ID on a particular row ?

I already tried to display the ID on a second column and get the ID by doing

:

GridViewUsers.SelectedRow.Cells[1].Text
But I don't want the ID to be displayed... I'm looking for other
alternatives.

Thanks!

I finally found a way but I wonder if it's "the" good way :

    protected void GridViewUsers_SelectedIndexChanged(object sender,
EventArgs e)
    {
        int userID =
(int)GridViewUsers.DataKeys[GridViewUsers.SelectedIndex].Value;
        [...]
    }

Thanks !!

Hi Mike

Glad you asked about this. I've been confronted with this sort of
problem too recently.

Your solution:

int userID =
int)GridViewUsers.DataKeys[GridViewUsers.SelectedIndex].Value;

could be a bit more direct with:

int userID = (int) GridViewUsers.SelectedValue;
