Selecting a cell from horizontally scrolled RadGrid with allowed Keyboard Navigationcauses the page to be scrolled to the left in IE 11.

Comment: If the Batch editing is enabled the cell is selected, but the batch editing is not started.

Code to reproduce the issue:
<div style="width: 4000px">
        <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" AllowSorting="true" Skin="Telerik" RenderMode="Lightweight"
            OnNeedDataSource="RadGrid1_NeedDataSource">
            <ClientSettings AllowKeyboardNavigation="true" Scrolling-AllowScroll="true" Scrolling-SaveScrollPosition="true">
                <Selecting CellSelectionMode="SingleCell" />
            </ClientSettings>
            <GroupingSettings ShowUnGroupButton="true"></GroupingSettings>
            <MasterTableView  CommandItemDisplay="Top" Frame="Border" ShowFooter="true" AllowPaging="True" AllowCustomPaging="true" ShowGroupFooter="true">
            </MasterTableView>
        </telerik:RadGrid>
</div>

If the selection mode of the Grid is different than row selection, no cell of the detailed grid gets selected. The bug is introduced with version 2016 R3 SP1

Steps to reproduce:
1. Run the following demo locally  http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarative-relations/defaultcs.aspx

2. and add this configuration:
       <telerik:RadGrid ...>
            <ClientSettings>
                <Selecting CellSelectionMode="SingleCell" />
            </ClientSettings>

The issue will not be fixed since there is a big chance to introduce a breaking change. Nevertheless, there is a simple solution that could be use. The solution is to manually remove the hidden column from the ClientState on the client.

    <script type="text/javascript">
        function test() {
            var gridID = $telerik.$(".RadGrid")[0].id;
            var clientState = document.getElementById(gridID + "_ClientState");
            var value = clientState.value;
            if (value) {
                var parsedValue = JSON.parse(value);
                parsedValue.hidedColumns = [];
                clientState.value = JSON.stringify(parsedValue);
            }
        }
    </script> 

When trying to batch edit cell values of the Grid via e.g., RadEditor (GridHTMLEditorColumn or RadEditor in EditItemTemplate of GridTemplateColumn) the cell value always result to a plain text. 

RadGrid VirtualScrolling does not scroll to the bottom when StaticHeaders are enabled. The issue could be observed in the attached project.

Update: Items is marked as Won't Fix as the behavior is expected and is due to the nature of the batch mode. Changing it will result in a breaking change.

The problem is a limitation in the current implementation. It is due to the fact that when drag and drop are enabled the grid selects the item(mousedown) using the built-in selection logic. Later when click is fired the row is again selected. The selection logic is designed in such way that if you try to select an item which is already selected it will first deselect it and later select it. It is rather complex and handles various scenarios, altering it will result in a breaking change which is not desirable.

The problem could be replicated in the attached page.

Hi,
I updated my code with version 2013.3.1114, but the method get_cell() of the GridDataItem has become case-sensitive.
I have some codes that with version 2012.3.1016 that was working correctly.
Is possibile to have the choice of case-sensitive / insensitive or at least have backward comaptibility ?
