Radgrid Virtual Scrolling lose records

[Lasly]

Hi,
I have the problems with a Virtual Scrolling :

1) I can not select the last item on the page because it goes immediately to the next page
2)I have a tab with a RadGrid with virtual scrolling.
If I am placed on the first page of the RadGrid and change tab and then I come back I see the page with the correct lines of the RadGrid.
If I am placed on the second page of the RadGrid and change tab and then I come back I see the page without RadGrid rows of data.
Why?

thanks

Hello Lasly,

Can you elaborate a bit more on your scenario? Please specify if the problem persists without virtual scrolling enabled. Are you loading the controls with ajax as shown in this online example? Also clarify how you populate the grid control with data.

I am looking forward for your reply.

Hi,
the problem don't persists without virtual scrolling enabled.
The first time (first time only) I call the page imposed RadGrid. (Pager, export, size etc.)
follows a small piece (I do not think that is the problem):

grid.MasterTableView.CommandItemSettings.ShowExportToCsvButton = true;
           grid.MasterTableView.CommandItemSettings.ShowExportToExcelButton = true;
           grid.MasterTableView.CommandItemSettings.ShowExportToPdfButton = true;
           grid.MasterTableView.CommandItemSettings.ShowExportToWordButton = true;
           grid.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Top;

           grid.HeaderStyle.Font.Bold = true;
           grid.HeaderStyle.HorizontalAlign = HorizontalAlign.Left;
           grid.ItemStyle.HorizontalAlign = HorizontalAlign.Left;
           grid.AlternatingItemStyle.HorizontalAlign = HorizontalAlign.Left;

           grid.MasterTableView.IsFilterItemExpanded = false;

           grid.AllowSorting = true;
           grid.AllowFilteringByColumn = true;
           grid.EnableHeaderContextFilterMenu = true;
           grid.EnableHeaderContextMenu = true;
           grid.GroupingSettings.CaseSensitive = false;

           grid.EnableLinqExpressions = false;

I use the  NeedDataSource to popolate the radgrid:

protected void grdElencoProprietari_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
          grdElencoProprietari.DataSource = CaricaProprietari();
        }

 Thanks

Hello Lasly,

I suggest that you try setting AutoPostBack property of TabStrip control to true and see if the issue still persists. Additionally, I am attaching a sample test project which is working properly. Please give it a try and let me know if it helps to resolve the described problem.
