Problem loading larger dataset

I m facing problem with loading datagrid with 1000 records . A javascript error pops up with message : Error:Loading XML

The grid gets loaded properly when there are 800 records.

Kindly suggest me how this can be worked out.

There is no size limitation in grid, most probably one of extra rows contains chars which corrupt XML syntax in not-escaped state ( < > & ) or some chars in encoding which differs from default encoding of XML document.

Please try to load the xml feed URL in separate browser window - if XML contains error browser will show details about error and its position.
