NeedDataSource Server Bind to a remote Wcf Service

[Mauro]

Hi,
     i would like to know if it is possible to know if it is possible to extract the pager information during the NeedDataSource event.

I supposed it can be done with a custom pager, but i would like to reuse basic pager.
I need this because i have not a local db, but have to call a remote wcf service with a simple call (no odata or similar).

If cannot, do you suggest ObjectDataSource or Custom Pager?

Thx in advance

<telerik:RadGrid ID="RadGridMain" runat="server" AllowSorting="True" AllowPaging="True" AllowFilteringByColumn="True" PageSize="12" 
OnNeedDataSource="RadGridTransazioni_NeedDataSource">

....

</telerik:RadGrid>

#Code behind
protected void RadGridMain_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e) {
  WcfClient client = new WcfClient();
  List<DataType> returnedData = client.ReturnData( <... sort, page number, number of records ...>);
  this.RadGridMain.DataSource = returnedData;
}

Hi Mauro,

If by the pager information you refer to the current page index and page size indeed you can extract this information inside the NeedDataSource event handler. An example on how to achieve this is provided below.

C#:

protected void RadGridMain_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
    {
        ....
        int currentpage = RadGridMain.CurrentPageIndex;
        int pageSize = RadGridMain.PageSize;
    }
