Hi Team
The Data Virtualization view.ItemsLoading += (s, args) => event not calling is there anything more to do with this . my code is below please help me on this.
C# code:-
VirtualView = new VirtualQueryableCollectionView() { LoadSize = 500, VirtualItemCount = 200 };
VirtualView.ItemsLoading += (s, e) =>
{
var querytoLoad = dcBusinessAccountingContext.GetDepositListingSPQuery(search, searchDate, status).OrderByDescending(o => o.TransactionDate).IncludeTotalCount(true).Sort(VirtualView.SortDescriptors).Where(VirtualView.FilterDescriptors).Skip(e.StartIndex).Take(e.ItemCount);
dcBusinessAccountingContext.Load<DepositsListingSP_Result>(querytoLoad, LoadBehavior.MergeIntoCurrent, false).Completed += (senders, args) =>
{
var lo = (LoadOperation)senders;
if (lo.TotalEntityCount != -1 && lo.TotalEntityCount != VirtualView.VirtualItemCount)
{
VirtualView.VirtualItemCount = lo.TotalEntityCount;
}
else
{
}
VirtualView.Load(e.StartIndex, lo.Entities);
newdepositListing.BusyIndicator.IsBusy = false;
SetGridLinesVisibility.SetGridLines(newdepositListing.dtgdepositList);
GridViewScrollViewer scrollViewer = newdepositListing.dtgdepositList.ChildrenOfType<GridViewScrollViewer>().FirstOrDefault();
objApplicationClass.AdjustFooterHeight(newdepositListing.dtgdepositList, false);
if (scrollViewer != null)
{
if (scrollViewer.ComputedVerticalScrollBarVisibility == System.Windows.Visibility.Visible)
{
objApplicationClass.AdjustFooterHeight(newdepositListing.dtgdepositList, false);
}
else
{
objApplicationClass.AdjustFooterHeight(newdepositListing.dtgdepositList, true);
}
}
};
};
newdepositListing.DataContext = VirtualView;
Xaml Code:-
<telerikpresentation:RadGridView x:Name="dtgdepositList" Margin="0" RowHeight="22" Grid.Row="1" Height="Auto"
BorderThickness="0,1,0,0" IsReadOnly="True"

Unfortunately with the supplied information I cannot figure out what is going on. Could you please try to isolate the problem you have in the sample project from my previous reply? Then you can send it to me for further investigation.
As a side note - you can check our online demo which demonstrates how to use RadGridView with VQCV.
