Hi
I have an xml file and try to load into datagridview, how can I save the xml after I sort it by desc?

VB

DS.ReadXml(Application.StartupPath & "\user.xml")
       Dim DS As New DataSet
       If DS.Tables(0).Rows.Count = 0 Then
           MsgBox("nothing")
       Else
           Dim i As Integer = 0
           For Each r As DataRow In DS.Tables(0).Rows
               dtgUser.Rows.Insert(i, r("ID"), r("Name"))
               i = i + 1
           Next
       End If
       dtgUser.Sort(dtgUser.Columns("ID"), System.ComponentModel.ListSortDirection.Ascending)

VB

Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
           
        DS.WriteXml(Application.StartupPath & "\user.xml")
            
    End Sub

Solution 2

You should sort the table before save to xml file:

VB

Dim dv As New Dataview(DS.Tables(0))
dv.Sort="ID DESC"
DS.Tables(0)=dv.ToTable
