We use the Telerik RadGrid for our application and we have found that if we click on the filter button on the RadGrid, it will make the page scroll.

For keyboard users who don't have a specific Context Menu key (see, they typically need to use the Windows standard SHIFT+F10 hotkey to trigger a contextmenu event.

For example:

1.	In IE, load
2.	Tab to a column header link
3.	Press SHIFT+F10 (standard Windows/IE hotkey to open context menu)
4.	Notice the context menu displays, however, the focus is really on the IE menubar. IE supports F10 to open the menubar, but is also seeing SHIFT+F10 too.

1.	In FireFox, load
2.	Tab to a column header link
3.	Press SHIFT+F10 (standard Windows/IE hotkey to open context menu) then press down arrow
4.	Notice the context menu displays, however, the focus is really on FireFox's application system menu in the upper left.

Chrome does not have this issue - it opens the grid context menu only.
We need IE and FireFox to also only open the grid's context menu, and not trigger default browser behavior.

According to, it is possible to correct this behavior by calling event.preventDefault() when SHIFT+F10 is pressed, but then trigger a synthetic contextmenu event anyway.

As a workaround, we know users can press Escape to close the browser's default menu and bring focus back into the HTML document (and thus the grid's context menu), but this throws off the user experience and becomes a training issue.

Since updating to the latest release of UI for ASP.NET AJAY the RadContextMenu of my RadGrid is misaligned at the right edge of the screen. Even in your sample when you open the context menu at the right side of the screen the context menu is nor aligned to the left (like it used to be).

Please ses the attached printscreen.

Kind regards

Exporting an empty RadGrid to XLSX or Biff with ExportSettings-ExportOnlyData="true" and Caption set, throws exception: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Steps to reproduce:

RadGrid markup:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true"
    <ExportSettings ExportOnlyData="true">
        <Excel Format="Biff" />
    <MasterTableView Caption="My Personalized caption" CommandItemDisplay="Top">
        <CommandItemSettings ShowExportToExcelButton="true" />

C# - Code behind

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    RadGrid1.DataSource = OrdersTable();
private DataTable OrdersTable()
    DataTable dt = new DataTable();
    dt.Columns.Add(new DataColumn("OrderID", typeof(int)));
    dt.Columns.Add(new DataColumn("OrderDate", typeof(DateTime)));
    dt.Columns.Add(new DataColumn("Freight", typeof(decimal)));
    dt.Columns.Add(new DataColumn("ShipName", typeof(string)));
    dt.Columns.Add(new DataColumn("ShipCountry", typeof(string)));
    dt.PrimaryKey = new DataColumn[] { dt.Columns["OrderID"] };
    return dt;

When the Grid has  <HeaderContextMenu> in the Markup and there is no explicitly set RenderMode of the Grid, the Grid is rendered in Classic. 
It also happens if there is a reference to the ContextMenu in the code behind.

Reproduction steps: 
    function f() {
<telerik:RadGrid ID="RadGrid1" runat="server" >  

1. Remove the HeaderContextMenu tag

2. Set the RenderMode of the Grid explicitly
