i need to get the gridview row id of a selected row. my issue is that I'm calling an object that I can't look into so I'm allowing the gridview to auto generate the columns. when the gridview is loaded i then need to be able to select a row and pass the rowid to a method. I have to click a button to load the data.
 I've already written the code to go after the data.

how do i code the selection of a row?
<asp:Button ID="btnListFiberTests" runat="server" 

                onclick="btnListFiberTests_Click" Text="List Fiber Tests" />



<asp:GridView ID="grdvwFiberTests" runat="server" CellPadding="4" 

                EnableModelValidation="True" ForeColor="#333333" GridLines="None" >

                <AlternatingRowStyle BackColor="White" ForeColor="#284775" />

                <EditRowStyle BackColor="#999999" />

                <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />

                <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />

                <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />

                <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />

                <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />

            </asp:GridView>



-----------------



 protected void btnListFiberTests_Click(object sender, EventArgs e)

        {

            //get all rows of data

            proxy = new FiberMossClient.FiberServiceReference.FiberServiceClient();

            fibertest = proxy.ListFiberTests();

            

            grdvwFiberTests.AutoGenerateColumns = true;

            grdvwFiberTests.DataSource = fibertest;

            grdvwFiberTests.DataBind();

        }

protected void button1_Click(object sender, EventArgs e)
{

   GridViewRow row = grdvwFiberTests.SelectedRow;

   // now to get the first col value

   string firstColValue = row.Cells[0].Text;

 // OR if you have set DataKeyNames property of the gridview to 'ID' column,
// SelectedValue property will give you the ID value directly
// DataKeyNames  => http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.datakeynames.aspx

   string selectedId = grdvwFiberTests.SelectedValue;

Below code shows adding a commandfield with Selectbutton...when user clicks the link on the row...that row will be selected, then GridView.SelectedRow or GridView.SelectedValue can be used as I mentioned above...
...

<Columns>

                    <asp:BoundField DataField="FiberTestId" HeaderText="Fiber Test Id" 

                        SortExpression="FiberTestId" />

                    <asp:BoundField DataField="WorkOrder" HeaderText="Work Order" 

                        SortExpression="WorkOrder" />

                    <asp:BoundField DataField="SerialNumber" HeaderText="Serial Number" 

                        SortExpression="SerialNumber" />

<asp:commandfield ShowSelectButton="true"

            headertext="Select"/>

</Columns>
