[RESOLVED] Datatable select ordering

Hi, I have a dataset generated from xml from a web service.

Data needs to be sorted by date order descending, I cannot get the web service changed so thought I'd try:

Code:

---

repeater1.DataSource = dsCombinedBlock.Tables(2).Select("Status < 3 and status <> 99", "DateReceived desc")

---

However the dates are treated as a string so the results look like

28/06/2011
27/06/2011
27/06/2011
02/06/2011
01/07/2011

How do I get the proper ordering applied.

thanks Dave

I thought perhaps the column had to be a type of date, then i ran into other problem
when trying to change the column type and import the data

Code:

---

If table1Success = True Then
                '// Table1
                UPRNjobs = UPRNjobs_C1.Clone
                UPRNjobs.Tables(2).Columns("DateReceived").DataType = GetType(Date)
                For Each dr As DataRow In UPRNjobs_C1.Tables(2).Rows
                    UPRNjobs.Tables(2).ImportRow(dr)
                Next
                If table2success = True Then
                    '// Combine both tables
                    For Each dr As DataRow In UPRNjobs_C2.Tables(2).Rows
                        UPRNjobs.Tables(2).ImportRow(dr)
                    Next
                End If
            Else
                If table2success = True Then
                    '// Table 2 only
                    UPRNjobs = UPRNjobs_C2.Clone
                    UPRNjobs.Tables(2).Columns("DateReceived").DataType = GetType(Date)
                    For Each dr As DataRow In UPRNjobs_C2.Tables(2).Rows
                        UPRNjobs.Tables(2).ImportRow(dr)
                    Next
                End If
            End If

I get this message

ForeignKeyConstraint Data_Row requires the child key values (0) to exist in the parent table.

not sure what the problem was, but i set enforeConstraints to false, and it works now. Doesn't seem like best solution but hey ho

Hello,

I would have to agree.

The best solution would be to get the Web Service to be able to return the data in the format required. You mentioned that there was no way to change the Web Service, is this a hard and fast decision?
