----------------------------------

             Summary: sorting a column in datagrid is very slow re: FLEX-18786 - is patch available for Flex SDK 3.2?
                 Key: FLEX-34588
                 URL: https://issues.apache.org/jira/browse/FLEX-34588
             Project: Apache Flex
          Issue Type: Question
          Components: Advanced Data Grid, mx: DataGrid
    Affects Versions: Adobe Flex SDK 3.2 (Release)
         Environment: Windows XP/7
Language: English
            Reporter: Peter Rieks
             Fix For: Adobe Flex SDK 3.2 (Release)


When we click on header to sort the data, below lines of code is responsible for sorting and refreshing the datagrid and its taking more time than expected.
Code snippet from Flex 3 Summary Dashboard
 
(datagrid.dataProvider as ICollectionView).sort = sortColumn;
(datagrid.dataProvider as ICollectionView).refresh();
 
Please note: It has been observed that its taking longer time to sort the Text fields than Numeric fields.

We believe this issue has already been solved, but only in Flex 4 - as per this > https://issues.apache.org/jira/browse/FLEX-18786

Is a patch available that can be used with Flex SDK 3.2?
