If you are using database ,then create functions for Update and Delete
Eg:
Public void Update(DataClass dataclass){…}
public void Delete(int Id){…}

Write these following code in your apsx page

                <Columns>
                    <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
                </Columns>

            </asp:GridView>
            <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" 
                DataObjectTypeName="DataClass" DeleteMethod="Delete" 
                TypeName="YourServiceClass" UpdateMethod="Update">
                <DeleteParameters>
                    <asp:Parameter Name="id" Type="Int32" />
                </DeleteParameters>
            </asp:ObjectDataSource>
