我收到此错误:
数据绑定方法,如Eval(),XPath()和Bind()只能是 在数据绑定控件的上下文中使用。
我正在尝试将SqlDataSource
的结果绑定到GridView
。
这是代码:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="grid_getbranch" Height="111px" Width="91px">
<Columns>
<asp:TemplateField HeaderText="branch" SortExpression="branch">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("branch") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("branch") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="name" SortExpression="name">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("name") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="grid_getbranch" runat="server"
ConnectionString="<%$ ConnectionStrings:svpolyConnectionString %>"
SelectCommand="SELECT branch.branch, course.name FROM branch INNER JOIN course ON branch.c_id = course.id WHERE (branch.c_id = @c_id)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList2" Name="c_id"
PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>

您可以尝试将SelectCommand查询更改为:
SELECT branch.branch AS branch, course.name AS name FROM branch INNER JOIN course ON branch.c_id = course.id WHERE (branch.c_id = @c_id)
我不确定这是否会导致您的错误,但这是我会尝试的第一件事。

删除绑定到标签字段。
