Hi.

When I use this select in a entitydatasource.CommandText:

CommandText="SELECT it.[LiteratureID], it.[ReleaseDate], it.[Title], it.[Text], it.[ThreadID], it.[Added], (SELECT COUNT(fp.PostID) FROM ForumPosts AS fp WHERE fp.ThreadID = it.[ThreadID] AND fp.Status = 1) AS Posts FROM Literature AS it WHERE it.[Status] = 4 ORDER BY it.[ReleaseDate] DESC SKIP 5 LIMIT 1"

I get this, when I bound the data:

System.Collections.Generic.List`1[System.Data.Common.DbDataRecord]

It should have been a number.

Solution 1

Found a solution.

Adding VALUE to the nested SELECT returned a list of Int32 insted.

Binding like this, returned the value:

Comments='<%# Eval("Posts[0]") %>'

Thanks very much. It is really a very appeciatable help.
I used in query like in aspx page :

<asp:entitydatasource id="LogsEntityDataSource" runat="server" connectionstring="name=CNDBEntities" xmlns:asp="#unknown">
DefaultContainerName="DBEntities" EnableFlattening="False" EntitySetName="Logs"
Select="it.Message, Count(it.Message) as Count, it.Logger as Location, it.Level, (Select VALUE l.Id from Logs as l where l.Message = it.Message and l.Logger = it.Logger and l.Level = it.Level) as Id"
GroupBy="it.Message,it.Logger,it.Level"
OrderBy="it.Count DESC" >

While binding written as said :
<a href="/logs/view-all.aspx?id=<%#Eval("Id[0]")%>">View All</a>Delete</a>

Thanks
