I am sure this has been answered a jillion times but i have looked and am not finding answers to my case -

i have a dataset i load up to pull data from while a user navigates the dataset.

if the user wants to sort the default load of the query, i would like to allow him to with the currently loaded dataset and not re-querying the actual database since his computer is super slow to begin with.

i put the basic dataset load below - basically want objds.tables("contacts").defaultview.sort = "LName DESC"

execute?!??!
objcon.Open()
        objDA = New OleDb.OleDbDataAdapter(strSQL, objcon)
        objDA.Fill(objDS, "Contacts")

        maxRows = objDS.Tables("Contacts").Rows.Count
        objcon.Close()

Open in new window

use the defaultView (see
http://weblogs.asp.net/jcogley/archive/2003/09/15/27567.aspx)
You could also use the "Select" command (which will return a sorted array of dataRows).  See http://msdn.microsoft.com/en-us/library/way3dy9w.aspx

You can create a dataview:

dtView = New DataView(dtTable, "", "fieldsort", DataViewRowState.CurrentRows)

After that you can bind the dataview to a control or cycle the rows in code like this:

        Dim dRow As DataRowView

        For Each dRow In dtView

                .....do stuff
        Next
