When pasting data into the Telerik Spreadsheet (using ctrl+v) I get the Page Unresponsive pop-up in Chrome and the Long Script running warning in Internet Explorer. This happens when pasting 3 columns of data (one string, two decimals) over 300 rows.
I have extended the number of rows using RowsCount="1000" in the telerik:RadSpreadsheet tag on the aspx page (.NET 4.0).
Any tips on:
1. Speeding up performance of the paste?
2. How to extend the time before Chrome shows the Page Unresponsive pop-up? For up to 750 rows the paste will complete after 5 pop-ups are dismissed.
