Hi,

In my app I currently have a Dataset with one table full of data. I need to be able to programmatically transfer all that data to a listview. As the number of rows and columns in the dataset may change I need the code to be able to cope with this too. Any ideas?

Thanks.

        'I am creating a dummy DataTable here you might have your own code to get
        'the dataTable filled
        Dim DT As New DataTable
        DT.Columns.Add("Name", GetType(String))
        DT.Columns.Add("Age", GetType(Integer))
        DT.Columns.Add("Address", GetType(String))
        Dim Dr As DataRow
        For i As Integer = 1 To 5
            Dr = DT.NewRow
            Dr(0) = "Name " & CStr(i)
            Dr(1) = 10 * i
            Dr(2) = "Address " & CStr(i)
            DT.Rows.Add(Dr)
        Next


        '---Code to show data in ListView from the DataTable
        'Since we are not adding images the view woould be Details type
        LstView.View = View.Details
        'Now Add Columns and Headers to the List View
        For Each DC As DataColumn In DT.Columns
            LstView.Columns.Add(DC.ColumnName)
        Next
        'Now Add the Rows
        Dim Itm As ListViewItem
        For Each Dr In DT.Rows
            Itm = New ListViewItem(Dr(0).ToString)
            Itm.SubItems.Add(Dr(1))
            Itm.SubItems.Add(Dr(2))
            LstView.Items.Add(Itm)
        Next

access the DataTable inside the Dataset like this YouDataSet.Tables(0)
so the code would change to

        LstView.View = View.Details
        For Each DC As DataColumn In YouDataSet.Tables(0).Columns '<-- Change the Dataset name here
            LstView.Columns.Add(DC.ColumnName)
        Next

        Dim Itm As ListViewItem
        For Each Dr In YouDataSet.Tables(0).Rows   '<-- Dataset name here
            Itm = New ListViewItem(Dr(0).ToString)
            Itm.SubItems.Add(Dr(1))
            Itm.SubItems.Add(Dr(2))
            LstView.Items.Add(Itm)
        Next
