Question

我有一个ListView，它有很多模板（InsertItemTemplate，AlternatingItemTemplate，EditItemTemplate，EmptyDataTemplate，ItemTemplate，LayoutTemplate，SelectedItemTemplate）

我有这个数据源：

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
 ConnectionString="<%$ ConnectionStrings:CouncilsConnectionString %>" 
 SelectCommand="SELECT [EmpID], [EmpName], [UserName], [password], [Email], [Mobile] FROM [Emp] WHERE ([FlageDel] = @FlageDel)"
 DeleteCommand="DELETE FROM Emp WHERE (EmpId = @did)"
 InsertCommand="INSERT INTO Emp(EmpName, UserName, password, Email, Mobile) VALUES (@inm, @ius, @ips, @iem, @imob)"
 UpdateCommand="UPDATE Emp SET EmpName = @ename, UserName = @nm, password = @ps, Email = @em, Mobile = @mob WHERE (EmpId = @eid)">
        <DeleteParameters>
            <asp:Parameter Name="did" />
        </DeleteParameters>
        <InsertParameters>
            <asp:Parameter Name="inm" />
            <asp:Parameter Name="ius" />
            <asp:Parameter Name="ips" />
            <asp:Parameter Name="iem" />
            <asp:Parameter Name="imob" />
        </InsertParameters>
        <SelectParameters>
            <asp:Parameter DefaultValue="0" Name="FlageDel" Type="Int32" />
        </SelectParameters>
        <UpdateParameters>
            <asp:Parameter Name="ename" />
            <asp:Parameter Name="nm" />
            <asp:Parameter Name="ps" />
            <asp:Parameter Name="em" />
            <asp:Parameter Name="mob" />
            <asp:Parameter Name="eid" />
        </UpdateParameters>
    </asp:SqlDataSource>

在ItemTemplate中我有

        <td>
            <asp:Button ID="DeleteButton" runat="server" CommandName="Delete" Text="Delete" />
            <asp:Button ID="EditButton" runat="server" CommandName="Edit" Text="Update" />
        </td>

我想知道如何将删除按钮与数据源命令相关联，以便在单击按钮时删除该项目。更新\插入操作也是一样。

这是整个ListView代码

<asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1" InsertItemPosition="LastItem">
        <AlternatingItemTemplate>
            <tr style="background-color: #FFFFFF;color: #000000;">

                    <asp:Button ID="DeleteButton" runat="server" CommandName="Delete" CommandArgument="@did" Text="حذف" />
                    <asp:Button ID="EditButton" runat="server" CommandName="Edit" Text="تعديل" />
                </td>
                <td>
                    <asp:Label ID="EmpNameLabel" runat="server" Text='<%# Eval("EmpName") %>' />
                </td>

抱歉延迟，但是删除按钮无效？通常当您使用模板时，它会自动将其设置为全部，因此当您单击删除按钮时，它会运行delete命令。但是，您当前拥有的参数

<InsertParameters>
        <asp:Parameter Name="inm" />
        <asp:Parameter Name="ius" />
        <asp:Parameter Name="ips" />
        <asp:Parameter Name="iem" />
        <asp:Parameter Name="imob" />
    </InsertParameters>

似乎没有做任何事情，你需要添加他们应该期待的东西。 IE字符串，char，int ......沿着这些行的东西。另一部分是您添加到按钮的命令参数。我认为你不需要那个。

对不起，如果这是超级晚了你已经弄清楚了。
