Question

我是菜鸟一个,可能很简单,别笑我啊!
在使用gridview控件时,启用了"启用删除",数据源里面也生成了删除啊,为什么点击"删除"后一点作用都不起呢???
代码如下:
---------------------------------------------
 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BackColor="White"
                        BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataSourceID="SqlDataSource1"
                        GridLines="Horizontal" Width="600px">
                        <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
                        <Columns>
                            <asp:BoundField DataField="Title" HeaderText="包含的栏目" SortExpression="Title">
                                <ItemStyle HorizontalAlign="Center" />
                            </asp:BoundField>
                            <asp:TemplateField HeaderText="修改">
                                <ItemStyle HorizontalAlign="Center" />
                                <ItemTemplate>
                                    <a href='edit.aspx?source=AboutUs&id=<%# Eval("USID") %>' class="lj1"><asp:Label ID="lblEdit" runat="server" Text='<%# db.book(Eval("USID").ToString()) %>'></asp:Label></a>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="预览">
                                <ItemStyle HorizontalAlign="Center" />
                                <ItemTemplate>
                                    <a href='PreView.aspx?source=AboutUs&id=<%# Eval("USID") %>' class="lj1"><asp:Label ID="lblPreview" runat="server" Text="预览" Enabled='<%# IsShow.showUs(Eval("USID").ToString()) %>'></asp:Label></a>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:BoundField DataField="DateTime" HeaderText="最后修改的时间" SortExpression="DateTime">

                        <AlternatingRowStyle BackColor="#F7F7F7" ForeColor="Black" Height="25px" />
                    </asp:GridView>
                    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:kunxiang %>"
                        SelectCommand="SELECT [USID], [Title], [DateTime] FROM [AboutUs] ORDER BY [DateTime] DESC" DeleteCommand="DELETE FROM [AboutUs] WHERE [USID] = @USID" InsertCommand="INSERT INTO [AboutUs] ([Title], [DateTime]) VALUES (@Title, @DateTime)" UpdateCommand="UPDATE [AboutUs] SET [Title] = @Title, [DateTime] = @DateTime WHERE [USID] = @USID">
                        <DeleteParameters>
                            <asp:Parameter Name="USID" Type="Int32" />
                        </DeleteParameters>
                        <UpdateParameters>
                            <asp:Parameter Name="Title" Type="String" />
                            <asp:Parameter Name="DateTime" Type="DateTime" />

                        <InsertParameters>
                            <asp:Parameter Name="Title" Type="String" />
                            <asp:Parameter Name="DateTime" Type="DateTime" />
                        </InsertParameters>
                    </asp:SqlDataSource>-------------------------
好象之前有一次成功过,不知道为什么多数时候不行;还有如果自己建了Template列,拖如个linkbutton,将其commandname设为delete,好象也可以啊
拜托
顺便祝大家五一快乐!!!!!!!!!!!

Answer 1

<asp:CommandField HeaderText="删除" ShowDeleteButton="True" ShowHeader="True">加个commandName = "delete"

Answer 2

在RowDeleted 事件中捕获异常Exceotion信息，并根据异常进行处理。异常是设计时必须考虑的。不处理异常，不算是正式的程序。

可是asp:CommandField里没有这个属性啊????

Answer 4

是没有,看错了,应该是
<asp:CommandField DeleteText="删除" ShowDeleteButton="true"

撞邪了,还是不行
是不是应该把"Eval"改成"Bind"啊?
可是我改成Bind后,却报错?
为什么?
真的这么复杂?
还是快放假了,我心已不在工作上了?
