Hello

I have a dataset which is successfully being filled. However whenever i try
to access a givewn row of one of the tables in the dataset i get the error

"Column 'ContactId' does not belong to table 'SalesAgent'"

Except that it does and if i use an ordinal reference i can access the value
of the column. If i print the schema sure enough the column is called
ContactId. I have also noticed that if i hover the cursor over the
contactrow i can access a treeview which lists all columns in the contactrow
and then tells me that none of them belong to table salesagent.

This was a conversion from 1.1 to 2.0. Any ideas?

Thanks
Lenny
 
Hi,

How exactly are you accessing data? And where are your columns defined?
 
Hi Miha,

The columns are defined as part of the strongly typed dataset schema. Im
accessing the data as follows:

If SalesTerritory.RelateSalesAgentsSalesTerritories(ds) Then
Dim contactRow As dsContact.ContactRow
contactRow =
CType(activeTerritory.GetParentRow(SalesTerritory.RELATION_SAST), _
dsContact.ContactRow)
If contactRow Is Nothing Then
Me.lblSalesAgent.Text = "<Unknown>"
Else
Me.ViewState.Add("SalesAgentId", contactRow.ContactId)
Me.lblSalesAgent.Text = contactRow.ContactName
End If
Else
Global_asax.DenyRequestInternalError()
End If

This fails at runtime on the line :Me.ViewState.Add("SalesAgentId",
contactRow.ContactId).
With the message as per the subject line. There is data in contactrow and
contactrow is not equal to nothing. If i use clng(contactrow(0)) i can get
the data and if i use contactRow("ContactId") i can get the data.


Thanks

Lenny
