i'm trying to sort a datatable using the typical select method*. The problem comes because the field is string defined but it's containing integer values.
With sql the problem will be solved just using something like:
select * from table order by to_number(field);
but of course it's not working properly with the method commented above (select method).

How can I change the parameter value from Interger to String.
Here below is the part of the code that creates problem; the constant "sqlStatement" is as string, but when the parameters "@ProdColor" read the value it returns an integer instead of the proper type which is a string. I have tried every ting like: CType(sqlStatement(splitItems(1)), string)
Or convert or parse, but it keeps returning the wrong type.
Const sqlStatement As String = "INSERT INTO ProductDetails (ProdID,ProdColor,ProdSize) VALUES"
If item.Contains(",") Then
splitItems = item.Split(",".ToCharArray)
cmd.Parameters.AddWithValue("@ProdID", SqlDBType.Int).Value = sqlStatement(splitItems(0))
cmd.Parameters.AddWithValue("@ProdColor", SqlDBType.NVarchar).Value = sqlStatement(splitItems(1))
cmd.Parameters.AddWithValue("@ProdSize", SqlDBType.NVarchar).Value = sqlStatement(splitItems(2))

but it only store the value 0 and not the value of the e.Record["UtstyrID)"])

The above code generated Option Strict On disallows implicit conversions from 'String' to 'Integer' error under the Item("Address") I don't know what i did wrong...
