You can to it before databind. Why do you have to do it at the time of databind?

What do you mean by before, it is coming from database and populating the labels

What format is your Data Source in? Dataset? DataTable? SQL/ODBC DataReader?

Dim ReturnedDataSet As New DataSet

Ok,

you really should do this when selecting the data originally however if this is not achieveable you can use the following

Solution 1 - Better solution causes less overhead and lets SQL provider/server do the work.

VB

Dim strSQL as string = "SELECT * FROM TravelData ORDER BY DepartureDate ASC, ArrivalDate ASC"

Solution 2:

VB

Private Sub GrabData()
    'Your Data Set
    Dim ReturnedDataSet As New DataSet

    '######
    '   Perform population here of your dataset
    '######

    'Perform The Sort
    Dim tmpDataView As New DataView(ReturnedDataSet.Tables(0)) With {.Sort = "DepartureDate ASC, ArriveDate ASC"}

    'Remove Original and Add
    ReturnedDataSet.Tables.Remove(0) : ReturnedDataSet.Tables.Add(tmpDataView.ToTable)

    MyDataGrid.DataSource = ReturnedDataSet
    MyDataGrid.DataBind()


End Sub
