The issue is replicated when the spreadsheet is higher than the screen height. To reproduce it, scroll the page and click the last visible cell.
Result: The page is scrolled to the beginning of the Spreadsheet element
Expected: The page is not scrolled
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1" Height="2000px" Width="100%">
</telerik:RadSpreadsheet>
Thank you for reporting this issue, Mamallan,
The following script can be used as a temporary workaround:
.RadSpreadsheet .k-spreadsheet-clipboard-paste,
.RadSpreadsheet .k-spreadsheet-clipboard {
position: fixed;
}
Regards,
