<asp:GridView ID="gvProduct" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" 
                                    OnRowCommand="gvProduct_RowCommand" Width="100%">
                                    <Columns>
                                        <asp:TemplateField>
                                            <ItemTemplate>
                                                <asp:ImageButton ID="btnEdit" runat="server" CommandName="EditCommand" ImageUrl="~/Images/Grid/edit.png"
                                                     />
                                            </ItemTemplate>
                                                                                        </asp:TemplateField>
                                        <asp:BoundField DataField="ProjectNo" />
                                        <asp:BoundField DataField="OrderLetterNo"  />
                                        <asp:BoundField DataField="Date"  />
                                        <asp:BoundField DataField="Saloon" />
                                        <asp:TemplateField>
                                            <ItemTemplate>
                                                <asp:ImageButton ID="btnDelete" runat="server" CommandName="DeleteCommand" ImageUrl="~/Images/Grid/delete.png" />
                                            </ItemTemplate>
                                                                                        </asp:TemplateField>
                                    </Columns>
                                    </asp:GridView>

and here is the code behind:

protected void gvProduct_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        GridViewRow Row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
        int rowID = Convert.ToInt32(gvProduct.DataKeys[Row.RowIndex].Value);

        if (e.CommandName == "EditCommand")
        {
            EditFunction(rowID);
        }
        else
            if (e.CommandName == "DeleteCommand")
            {
                DeleteFunction(rowID);
            }
    }
