Slow response pasting data into spreadsheet

[Rick]

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.

 

Thanks,

Rick

We decided that the Import File option on the Telerik Spreadsheet solved our issue. Very fast import of 10000 rows and saved it to a database with the custom SpreadsheetDataBase Provider.
