asp.net Gridview: buttons accessing data for each row

Question

I'm trying to code a Gridview that has a button on each row that when clicked will expose that particular rows data for use, but I'm not sure how the data would be passed.

The Gridview:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID"
    DataSourceID="SqlDataSource2">
    <Columns>
        <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True"
            SortExpression="ID" Visible="False" />
        <asp:BoundField DataField="RelationID" HeaderText="RelationID" InsertVisible="False"
            SortExpression="RelationID" Visible="False" />
        <asp:BoundField DataField="UserRole" HeaderText="UserRole" InsertVisible="False"
            SortExpression="UserRole" Visible="False" />
        <asp:BoundField DataField="FirstName" HeaderText="First Name" SortExpression="FirstName" />
        <asp:BoundField DataField="Surname" HeaderText="Surname" SortExpression="Surname" />
        <asp:BoundField DataField="Telephone" HeaderText="Telephone" SortExpression="Telephone" />
        <asp:BoundField DataField="Email" HeaderText="Email" SortExpression="Email" />
        <asp:BoundField DataField="Hash" HeaderText="Hash" InsertVisible="False" SortExpression="Hash"
            Visible="False" />
        <asp:BoundField DataField="DateCreated" HeaderText="Date Invited" SortExpression="DateCreated" />
        <asp:TemplateField HeaderText="Resend Welcome Email">
            <ItemTemplate>
            <asp:Button runat="server" ID="btnResend" Text="Resend" OnClick="btnResend_Click" />
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
        </asp:TemplateField>
    </Columns>
</asp:GridView>

The button_OnClick

protected void btnResend_Click(object sender, EventArgs e)
{
    bool boolEmailSent = Email.sendWelcomeEmail(//Email from Row, //FirstName from Row, //Surname from Row, //Hash from Row);

    if (boolEmailSent == true)
    {
        //Confirm to User
    }
    else
    {
        //TODO: write error to log
    }
}
