I searched the net a lot for this task. But no direct and clear help I got. But I have figured it out from the information I have gathered.

I would like to share with those who are looking for the same.

We want to retrieve the values of two databound fileds
"usernm" visible = true
"userno" visible = false

set the property (in design view)


gridview.datakeynames as  "userno,usernm"

For runtime (in the page load event)


gridview1.datakeynames = "userno,usernm".split(",")  
                (split is used to make it 1 - dimensional array)

            dc = New BoundField
            strName = "userno"
            dc.DataField = strName
            dc.Visible = False
            GridView1.Columns.Add(dc)
            GridView1.DataKeyNames = "userno".Split(" ")  and....usernm too.

We can retrieve the value of the invisible field as follow. ( I used in rowcommand event)


        Dim Userno As String
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        Userno = GridView1.DataKeys(index).Item(0).ToString
        Label2.Text = Userno

Hope it helps those who is search of it.
