Question

当我在文件后面调用代码时，我收到此错误。

过程或函数'GetALLSurveyor_ForTeam_Update'需要参数'@ID'，这是未提供的。

我的代码是

sdsSurveyor.SelectParameters.Add("@ID", TeamID)
sdsSurveyor.SelectCommand = "GetALLSurveyor_ForTeam_Update"
sdsSurveyor.InsertCommandType = SqlDataSourceCommandType.StoredProcedure

chklistsurveyor.DataSourceID = "sdsSurveyor"
chklistsurveyor.DataBind()

并在aspx文件中

<asp:CheckBoxList ID="chklistsurveyor" CellSpacing="10" CellPadding="10" RepeatLayout="Table"
     CssClass="mycheckbox" TextAlign="Right" DataTextField="NAME" DataValueField="ID"
     RepeatDirection="Horizontal" RepeatColumns="2" runat="server">
</asp:CheckBoxList>
<asp:SqlDataSource ID="sdsSurveyor" ConnectionString="<%$ ConnectionStrings:ApplicationServices%>" runat="server">
</asp:SqlDataSource>

您也需要将sdsSurveyor.SelectCommandType设置为SqlDataSourceCommandType.StoredProcedure！（不仅仅是代码中的.InsertCommandType）：

sdsSurveyor.SelectParameters.Add("@ID", TeamID)
sdsSurveyor.SelectCommand = "GetALLSurveyor_ForTeam_Update"

// make sure you have this line in there somewhere 
sdsSurveyor.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
