EntityDataSource问题 [英] EntityDataSource Issue

问题描述

好的，经过一小时的尝试和错误，我决定发布问题。

 Ok, after hour of try and error I decided to post the question.

我试图将Entlude属性与EntityDataSource的Select属性结合使用。

I am trying to use the Include property in conjuction with the Select property of the EntityDataSource.

我收到以下错误：

查询的结果类型既不是EntityType，也不是具有实体元素类型的CollectionType 。只能为具有这些结果类型之一的查询指定包含路径。

如果我不使用Include属性，一切都很好但当然我也需要组织，因为我有1：N关系：

If I don't user the Includeproperty everything is fine but of course I also need the Organization because I have 1:N relation:

< asp ： EntityDataSource ID =" EntityDataSource_PracticeSite" runat =" server" ConnectionString =" name = RecruitmentAndRetentionEntities" ; DefaultContainerName =" RecruitmentAndRetentionEntities" EntitySetName =" PracticeSite" 选择 = " it.PracticeSiteID，it.Name，Count（it.PracticeSiteID）AS P" GroupBy =" it.PracticeSiteID，it.Name" 包含 =" Organization">

<asp:EntityDataSource ID="EntityDataSource_PracticeSite" runat="server" ConnectionString="name=RecruitmentAndRetentionEntities" DefaultContainerName="RecruitmentAndRetentionEntities" EntitySetName="PracticeSite" Select= "it.PracticeSiteID, it.Name, Count(it.PracticeSiteID) AS P" GroupBy="it.PracticeSiteID, it.Name" Include="Organization">

任何帮助都将不胜感激。

Any help would be appreciated.

谢谢
