I have one more problem is
Actually my requirement is I have Upload button in cell of datagrid.When i clicked on upload button
u will get file selection window.Now i selected file and it will be added to cell(file1).After that i have selected
one more file and it will be added to same cell(file2 below the file1).Here i dont want to allow the duplicate file names in that cell.
How to solve this problem?
For the name, you can check the uploaded file name with the FileReference name property, once the file selection has been made.
For the IOError, I think you should handle it with an event listener on the FileReference, for the IOErrorEvent.IO_ERROR event, and no try/catch block.
