Hi,
Ok but where do I set this VirtualItemCount property? I have tried but it made no difference.
| Private Function GetParts() As System.Data.DataTable |
| Dim DA190Component As New DA190Component() |
| Dim table As System.Data.DataTable = Nothing |
| |
| Me.RadGrid1.VirtualItemCount = 360 |
| |
| 'The code below calls my business object and returns only the number of records |
| 'as specified by the PageSize property of the rad grid - see parameters. |
| |
| table = DA190Component.GetDA190ComponentListView2(ViewState.Item(Constants.PAR_CERTIFICATE_NO), Me.RadGrid1.CurrentPageIndex, Me.RadGrid1.PageSize, ViewState.Item(Constants.PAR_MANAGE_PARTS_FILTER)) |
| |
| Return table |
| End Function |
Now this function I call from the following places, so each time it needs data
like when paging occurs it fires the NeedDataSource event I pressume which in turn will call GetParts() which will ask the business objects for the next set of correct 15 or 10 records - depending on the PageSize (which is fixed at design time)
| Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load |
| If (Not IsPostBack) Then |
| RadGrid1.DataBind() |
| End If |
| End Sub |
| Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource |
| RadGrid1.DataSource = GetParts() |
| End Sub |
