我们在写项目的时候经常会遇到要做一些比较简单的基础信息,这些东西如果也用表单的话就显得比较麻烦,这里介绍一下用GridView方法的简单实例,示例仅供参考．

1.数据模型

2.页面代码
1 <%@ Control Language="C#" AutoEventWireup="True" CodeBehind="RolesList.ascx.cs" Inherits="ZhuJi.UUMS.WebUI.RolesList" %>

2 <asp:GridView ID="gvList" runat="server" AutoGenerateColumns="False" OnRowCancelingEdit="gvList_RowCancelingEdit"

3 OnRowDeleting="gvList_RowDeleting" OnRowEditing="gvList_RowEditing" OnRowUpdating="gvList_RowUpdating"

4 Width="100%" ShowFooter="True">

5 <Columns>

6 <asp:BoundField DataField="Id" HeaderText="标识" ReadOnly="True">

7 <ItemStyle HorizontalAlign="Center" Width="48px" />

8 </asp:BoundField>

9 <asp:TemplateField HeaderText="角色名称">

10 <EditItemTemplate>

11 <asp:TextBox ID="txtRoleName" runat="server" Text='<%# Bind("RoleName") %>' Width="300px"></asp:TextBox>

12 </EditItemTemplate>

13 <ItemTemplate>

14 <asp:Label ID="lblRoleName" runat="server" Text='<%# Bind("RoleName") %>'></asp:Label>

15 </ItemTemplate>

16 <FooterTemplate>

17 <asp:TextBox ID="txtRoleName" runat="server" Width="300px"></asp:TextBox>

18 </FooterTemplate>

19 </asp:TemplateField>

20 <asp:TemplateField HeaderText="排序">

21 <EditItemTemplate>

22 <asp:TextBox ID="txtOrderBy" runat="server" Text='<%# Bind("OrderBy") %>' Width="100%"></asp:TextBox>

23 </EditItemTemplate>

24 <ItemStyle HorizontalAlign="Center" Width="48px" />

25 <ItemTemplate>

26 <asp:Label ID="lblOrderBy" runat="server" Text='<%# Bind("OrderBy") %>'></asp:Label>

27 </ItemTemplate>

28 <FooterStyle HorizontalAlign="Center" Width="48px" />

29 <FooterTemplate>

30 <asp:TextBox ID="txtOrderBy" runat="server" Width="48px"></asp:TextBox>

31 </FooterTemplate>

32 </asp:TemplateField>

33 <asp:TemplateField ShowHeader="False">

34 <EditItemTemplate>

35 <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" CommandName="Update"

36 Text="更新"></asp:LinkButton>

37 <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="Cancel"

38 Text="取消"></asp:LinkButton>

39 <asp:LinkButton ID="LinkButton3" runat="server" CausesValidation="False" CommandName="Delete"

40 Text="删除"></asp:LinkButton>

41 </EditItemTemplate>

42 <ItemStyle HorizontalAlign="Center" Width="100px" />

43 <ItemTemplate>

44 <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Edit"

45 Text="编辑"></asp:LinkButton>

46 <asp:LinkButton ID="LinkButton3" runat="server" CausesValidation="False" CommandName="Delete"

47 Text="删除"></asp:LinkButton>

48 </ItemTemplate>

49 <FooterStyle HorizontalAlign="Center" Width="100px" />

50 <FooterTemplate>

51 <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" OnClick="gvList_RowInserting"

52 Text="新建"></asp:LinkButton>

53 </FooterTemplate>

54 </asp:TemplateField>

55 </Columns>

56 <HeaderStyle Height="30px" />
