我有一个Detailsview对象,当从gridview中单击User时,该对象加载了用户数据。问题是,我正在使用sqldatasource,而我宁愿使用我之前存在的用户类,它具有所有内置功能。我无法正确完成这项工作。在没有sqldatasource的情况下,我无法使用用户数据填充detailsview,当我尝试使用我的对象插入或更新时,它会运行插入/更新代码,然后因为我没有InsertCommand等而失败SQLDataSource ....底线...有人可以帮助我在不需要SQLDataSource的情况下工作吗?
这是我的代码。
<asp:GridView runat="server" ID="gvUsers" DataKeyNames="UserID" BackColor="#eeeeee" Width="85%"
HorizontalAlign="Center"
Font-Bold="True" Font-Names="Verdana"
Font-Size="10pt" AutoGenerateColumns="False"
OnRowDataBound="GridView1_RowDataBound"
OnRowDeleting="GridView1_RowDeleting" >
<HeaderStyle BackColor="Black" ForeColor="White"
Font-Bold="True" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="yellow" ForeColor="blue" />
<AlternatingRowStyle BackColor="#ffffff" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton2"
CommandArgument='<%# Eval("UserID") %>'
CommandName="Select" runat="server">
Select</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="UserID" Visible="false" />
<asp:BoundField DataField="FirstName" HeaderText="First Name" />
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
<asp:TemplateField HeaderText="Delete?">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1"
CommandArgument='<%# Eval("UserID") %>'
CommandName="Delete" runat="server">

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView><br /><br />
<asp:DetailsView runat="server" ID="dvUser" DataSourceID="SqlDataSource3" AutoGenerateRows="False" Width="85%"
HorizontalAlign="Center" DataKeyNames="UserID">
<Fields>
<asp:BoundField DataField="UserID" Visible="false" />
<asp:BoundField DataField="FirstName" HeaderText="First Name" />
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
<asp:BoundField DataField="UserName" HeaderText="User Name" />
<asp:BoundField DataField="Password" HeaderText="Password" />
<asp:BoundField DataField="Birthdate" HeaderText="Birthdate" />
<asp:BoundField DataField="Address" HeaderText="Address" />
<asp:BoundField DataField="Apt" HeaderText="Apt" />
<asp:BoundField DataField="City" HeaderText="City" />
<asp:BoundField DataField="Province" HeaderText="Province" />
<asp:BoundField DataField="PostalCode" HeaderText="PostalCode" />
<asp:BoundField DataField="PhoneNum" HeaderText="PhoneNum" />
<asp:BoundField DataField="Email" HeaderText="Email" />
<asp:BoundField DataField="ynAdminUser" HeaderText="ynAdminUser" />
<asp:CommandField ShowDeleteButton="False" ShowEditButton="True" ShowInsertButton="True" />
</Fields>
</asp:DetailsView>
<asp:SqlDataSource ConnectionString="<%$ ConnectionStrings:ConnectionString%>" ID="SqlDataSource3"
runat="server" SelectCommand="sp_GetUser" SelectCommandType="StoredProcedure" OnInserting="OnInserting" >
<SelectParameters>
<asp:ControlParameter ControlID="gvUsers" Name="UserID" PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
不确定CodeBehind是否必要,我只是想用它来调用我的数据对象代码进行更新,插入等

为什么不使用ObjectDataSource。此控件的工作方式与SqlDataSource非常相似,但您无需指定SQL查询或存储过程,而是指定自定义业务对象的方法来执行数据访问。
<asp:ObjectDataSource ID="ObjectDataSource" Drunat="server" DeleteMethod="Delete"
InsertMethod="Insert" SelectMethod="Select" UpdateMethod="Update" TypeName="YourType">
Here's一个示例,说明如何将ObjectDataSource与DetailsView一起使用。
