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>

It seems the element somehow considmes the scrolling/touch action and the grid does not scroll unless you hit the gap where the custom element does not reach.

A workaround is to enforce overflow: auto to the scrollable element of the grid. A sample is attached below.

        div.rgDataDiv {
            overflow: auto !important;
        }

When page scrolling is enabled and scrolling down the page, the row context menu of RadGrid rows do not open at a correct position.

There are two possible approaches to overcome this issue:
- First approach would be to get a reference to the GridHTMLEditorColumn and add the desired tools in the code behind using the "OnItemCreated" server event handler of RadGrid.
- Second approach would be to use GridTemplateColumn with RadEditor.

The reason for the behavior is that the column editor does not move to the cell when you cancel its opening. Opening a cell in the same column expects the column editor to be in the previously opened cell, however, and this causes the error. Repro is attached to illustrate the scenario.

Workarounds:
- Use EditType=Cell so that each cell opens independently of the row (wokaround 1).
- Use the provided function override (workaround 2). Make sure to remove it after upgrading to a release that has the fix. This function override may prevent you from getting other updates and fixes in this function.
- Use a template column and hide the editor based on your condition in the OnBatchEditOpened event (workaround 3)

Th header context menu of the Grid gets closed on click (select/deselect a column) if the Grid is initially scrolled horizontally.

Steps to reproduce:
    1. Open the Live Demos solution for "UI for ASP.NET AJAX R1 2017" in VS2015;
    2. Open the page "UI for ASP.NET AJAX R1 2017\Live Demos\Grid\Examples\Functionality\Scrolling\scrolling\DefaultCS.aspx";
    3. Enable the HeaderContextMenu by setting EnableHeaderContextMenu="True" in the tag telerik:RadGrid;
    4. Disable the column freezing.
    5. Run the Demo and open the page "Grid\Examples\Functionality\Scrolling\scrolling\DefaultCS.aspx";
    6. Scroll the horizontal scrollbar of the grid to the right;
    7. Right click on the column header and pick the Columns from the context menu;
    8. Select or unselect any column, the Column Chooser will close by itself;
    9. Now, scroll the horizontal scrollbar of the grid all the way to the left;
    10. Right click on the column header and pick the Column Chooser from the context menu;
    11. Select or unselect any columns, the Column Chooser won't close by itself.

Hi Team Telerik,

i found a bug in RadGrid. This one only appears in Chrome Webbrowser.
Columnresizing only works once per column in chrome. You can see it right the way in your demo-site. Go to the Resizing Demopart and resize one column. Now try to re-resize it. It wont work. 

Best wishes Philipp

with client-side databinding when setting sort/filter expressions on button click and then calling the rebind or set_currentPageIndex methods the control makes multiple requests to the web service.

There are two easy solutions:
- set HighlightDeletedRows to false
- use the built-in Save Changes button in the command item

A workaround is attached that allows you to use an external button and highlight deleted rows.
It will cause other changes apart from deletion on a row to be lost, but deleted rows will be sent to the server.

If paging is disabled and the PageSize is set to less than the number of records bound to RadGrid, client item templates are not all rendered correctly.

Example:

If PageSize is 10, and records bound to Grid are 15, then the first 10 records will have templates rendered correctly, while the rest of 5 records will not.

Assuming the following configuration for RadGrid:

• RenderMode="Mobile"
• AllowSorting="true"

Testing using a mobile device (e.g. Chrome in Galaxy Nexus)

Test case 1:

If I click on middle of three dots Icon, then RadGrid opens the options menu

Test case 2:

If I click a bit below of the three dots Icon, then RadGrid does a sort on the column automatically

We are still experiencing a problem with the RadGrid and JAWS when aria support is enabled. The JAWS form fields dialog (INS+F5) renders all elements of the grid on a single line.
