Hi,

I have tried to set the VirtualItemCount in the PageLoad and it works fine at my end.Here is the code snippet.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">   


    <AjaxSettings>

        <telerik:AjaxSetting AjaxControlID="RadGrid1">

            <UpdatedControls>

                <telerik:AjaxUpdatedControl ControlID="RadGrid1"></telerik:AjaxUpdatedControl>

            </UpdatedControls>

        </telerik:AjaxSetting>

    </AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" ToolTip="" runat="server">

</telerik:RadAjaxLoadingPanel>

<telerik:RadGrid ID="RadGrid1" ShowGroupPanel="true" AllowFilteringByColumn="true" runat="server" AllowPaging="True" AllowSorting="true"    AllowCustomPaging="True" OnNeedDataSource="RadGrid1_NeedDataSource" OnGroupsChanging="RadGrid1_GroupsChanging"    OnColumnCreated="RadGrid1_ColumnCreated" >  

</telerik:RadGrid>

C#:

protected void Page_Load(object sender, EventArgs e)

   {

       RadGrid1.VirtualItemCount = 10000;//Set the VirtualItemCount

   }

     protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

       {

           MyBusinessObjects MyBusinessObjectCollection1 = new MyBusinessObjects();

           int startRowIndex = (ShouldApplySortFilterOrGroup()) ?

               0 : RadGrid1.CurrentPageIndex * RadGrid1.PageSize;

 

           int maximumRows = (ShouldApplySortFilterOrGroup()) ?

               MyBusinessObjectCollection1.SelectCount() : RadGrid1.PageSize;

 

           RadGrid1.AllowCustomPaging = !ShouldApplySortFilterOrGroup();

           RadGrid1.DataSource = MyBusinessObjectCollection1.Select(startRowIndex, maximumRows);

       }

 

       bool isGrouping = false;

       protected void RadGrid1_GroupsChanging(object source, GridGroupsChangingEventArgs e)

       {

           isGrouping = true;

           if (e.Action == GridGroupsChangingAction.Ungroup && RadGrid1.CurrentPageIndex > 0)

           {

               isGrouping = false;

           }

       }

 

       public bool ShouldApplySortFilterOrGroup()

       {

           return RadGrid1.MasterTableView.FilterExpression != "" ||

          RadGrid1.MasterTableView.GroupByExpressions.Count > 0 || isGrouping) ||

          RadGrid1.MasterTableView.SortExpressions.Count > 0;

       }

 

       protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)

       {

           if(e.Column.IsBoundToFieldName("Date"))

           {

             (e.Column as GridDateTimeColumn).DataFormatString = "{0:D}";

           }

           else if (e.Column.IsBoundToFieldName("UnitPrice"))

           {

             (e.Column as GridNumericColumn).DataFormatString = "{0:C}";

           }

         if (e.Column is GridBoundColumn)

          {

            (e.Column as GridBoundColumn).FilterControlWidth = Unit.Pixel(100);

          }

       }

Hi Princy,
Finally I found other solutions, set ItermVirtualCount from ASPX using  ItemVirtualCount ="<%# GetCount() %>"

In server side 

public int GetCount(){
return "Number" ; 
}
