Error when databinding

[Nathan Sokalski]

When I run my application, which uses databinding in a DataList, I recieve the following error:

Server Error in '/' Application.
--------------------------------------------------------------------------------

Public member 'title' on type 'DataRowView' not found.

I cannot figure out why this is happening. The code I use to do the binding, which I call from Page_Load using Me.SortPoems("title") is as follows:


Private Sub SortPoems(ByVal sortby As String)
Dim ratedpoems As New DataSet
Dim sqltext As String = "SELECT * FROM poemratings ORDER BY "

Select Case sortby
Case "title"
sqltext &= "title"
Case "rating"
sqltext &= "(totalpoints/timesrated),timesrated,title"
Case "timesrated"
sqltext &= "timesrated,(totalpoints/timesrated),title"
End Select
Dim dataadapterSelect As New System.Data.OleDb.OleDbDataAdapter(sqltext, Global.GetDBConnection())
dataadapterSelect.Fill(ratedpoems)
datRatings.DataSource = ratedpoems
datRatings.DataBind()
End Sub


I have tried several experiments (such as removing the databinding expressions that use the field, but the same thing happens with the other fields). Why is ASP.NET telling me the field is not there? Any help would be appreciated. Thanks.

Try it in this case with a datatable.

I hope this helps,
