You can get it in the RowCommand event of the gridview.

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Edit")
    {
        e.CommandArgument // Return Primary key
        GridViewRow row = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
        row.Cells[0].///
        row.Cells[1].///
        ................
    }
}

C# – Get int value from enum in C#

Just cast the enum, e.g.

int something = (int) Question.Role;

The above will work for the vast majority of enums you see in the wild, as the default underlying type for an enum is int.

However, as cecilphillip points out, enums can have different underlying types. If an enum is declared as a uint, long, or ulong, it should be cast to the type of the enum; e.g. for

enum StarsInMilkyWay:long {Sun = 1, V645Centauri = 2 .. Wolf424B = 2147483649};

you should use

long something = (long)StarsInMilkyWay.Wolf424B;
