Timer to Refesh Grid Data

[bradley baker]

Do I need to do anything other than below to refresh a gridview?  (Im talking about the TableAdapter.Fill, will this cause the grid to rebind to the data automatically or do I need to include that also?  (It currenly appears to be working when the timer is up it does seem to freeze up the app for a few seconds as it downloads the huge dataset but because there is so much data and it maybe 5-10min between a change its kind of hard for me to see if a change happens.

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Dim Diff As TimeSpan = TargetTime.Subtract(Now)
        If Diff.Seconds = 0 And Diff.Minutes = 0 Then
            Label1.Text = "Data Refresh Now!  Stand By!"
            Me.ExpediteTableAdapter.CommandTimeout = 0
            Me.ExpediteTableAdapter.Fill(Me.MSQL_ERPLXFDataSet.Expedite)
            TargetTime = Now.AddMinutes(30)
        ElseIf Diff.Seconds < 0 And Diff.Minutes >= 0 Then
            Label1.Text = "-" & Format(Diff.Minutes, "#0") & ":" & Format(System.Math.Abs(Diff.Seconds), "00")
        Else
            Label1.Text = "Data Refresh In " & Format(Diff.Minutes, "#0") & ":" & Format(System.Math.Abs(Diff.Seconds), "00")
        End If
    End Sub

Hello bradley baker,

The only operation needed for an update operation in a bound RadGridView in you case is calling Fill on the adapter. RadGridView handles the ListChanged event of the bound IBindingList object (in this case DataTable/DataView) and automatically refreshes its rendered data.
