我在接受 4 个参数的 DB 中存储了过程。当我从 SQLDatasource 调用此过程并通过 sqldatasource 向导传递其参数时，我收到以下错误

错误 [42000] [Microsoft][ODBC SQL Server Driver][SQL Server] 过程或函数“director_proc”需要参数“@Department”，但未提供该参数。

下面是sqldatasource标签和存储过程的代码

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>" 
SelectCommand="director_proc" SelectCommandType="StoredProcedure">
 <SelectParameters>
<asp:ControlParameter ControlID="ASPxComboBox1" DbType="String" 
DefaultValue="Enterprise solution" Name="Department" PropertyName="Value" 
Type="String" />
 <asp:ControlParameter ControlID="ASPxComboBox2" DbType="String" 
DefaultValue="Enterprise operations" Name="Section" PropertyName="Value" 
Type="String" />
<asp:ControlParameter ControlID="MonthEdit1" DbType="Int16" DefaultValue="7" 
Name="Month" PropertyName="Month" Type="Decimal" />
<asp:ControlParameter ControlID="ASPxComboBox3" DbType="Int16" 
 DefaultValue="2013" Name="Year" PropertyName="Value" Type="Decimal" />
 </SelectParameters>
</asp:SqlDataSource>

伙计们的好消息是我成功地解决了这个问题。我正在使用 odbc 连接，似乎在通过 ODBC 连接传递参数时发生错误。所以我删除了 odbc 并将其替换为常规 sql 连接，一切正常。

感谢你的帮助。

我认为问题在于您绑定到 DevExpress 组合框。尝试AutoPostback="true"在您的 ASPxComboBox 控件上进行设置。另外，请确保您的 SqlDataSource 与 DevExpress 控件在同一个命名容器中......他们过去曾遇到过问题，但我多年来没有使用它们，所以我不知道它是否仍然是一个问题。

代替：

        <asp:ControlParameter ControlID="ASPxComboBox1" DbType="String" DefaultValue="Enterprise solution" Name="Department" PropertyName="Value" Type="String" />

尝试：

        <asp:ControlParameter ControlID="ASPxComboBox1" DbType="String" DefaultValue="Enterprise solution" Name="Department" PropertyName="SelectedValue" Type="String" />

尝试使用SelectedItem.Value而不是组合框的 Control 参数值。

 <SelectParameters>
      <asp:ControlParameter ControlID="ASPxComboBox1" DbType="String" 
       DefaultValue="Enterprise solution" Name="Department"  
       PropertyName="SelectedItem.Value" 
       Type="String" />
    <asp:ControlParameter ControlID="ASPxComboBox2" DbType="String" 
       DefaultValue="Enterprise operations" Name="Section"     
       PropertyName="SelectedItem.Value" 
       Type="String" />
   <asp:ControlParameter ControlID="MonthEdit1" DbType="Int16" DefaultValue="7" 
       Name="Month" PropertyName="Month" Type="Decimal" />
   <asp:ControlParameter ControlID="ASPxComboBox3" DbType="Int16" 
       DefaultValue="2013" Name="Year" PropertyName="SelectedItem.Value" Type="Decimal" />
    </SelectParameters>
