在GridView中应该用分页、编辑、删除、更新操作！

ASPX

<asp:GridView ID="gvwDepartments" runat="server" OnRowCancelingEdit="gvDepartment_RowCancelingEdit"
                OnRowEditing="gvDepartment_RowEditing" OnRowUpdating="gvDepartment_RowUpdating"
                OnRowDeleting="gvDepartment_RowDeleting">
                <Columns>
                    <asp:TemplateField HeaderText="部门名称">
                        <EditItemTemplate>
                            <asp:TextBox ID="txtDepName" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox>
                            <asp:RequiredFieldValidator ID="rfvDepartment" runat="server" ControlToValidate="txtDepName"
                                ErrorMessage="请填写 部门名称。"></asp:RequiredFieldValidator>
                            <asp:HiddenField ID="hfID" runat="server" Value='<%# Bind("ID") %>' />
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
                            <asp:HiddenField ID="hfID" Value='<%# Bind("ID") %>' runat="server" />
                        </ItemTemplate>
                        <ItemStyle Width="400px" />
                    </asp:TemplateField>
                    <asp:TemplateField ShowHeader="False">
                        <EditItemTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" CommandName="Update"
                                Text="更新"></asp:LinkButton>
                            <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="Cancel"
                                Text="取消"></asp:LinkButton>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Edit"
                                Text="编辑"></asp:LinkButton>
                            <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="Delete"
                                Text="删除" OnClientClick="return confirm('确定删除该部门信息吗？');"></asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
            </asp:GridView>

要注意的是这几个事件一定不可少
分页：OnPageIndexChanging
编辑：OnRowEditing
更新：OnRowUpdating
退出编辑：OnRowCancelingEdit
删除：OnRowDeleting

在后台类中对其进行定义，实现事件的操作。
