    Hello,







    First of all, make sure you are using the latest maintenance release of Spread for Web Forms (version 1.0.5.0). We are constantly making changes to the excel import/export code to improve it. If there is still a problem, could you email us at fpsupport@fpoint.com you spread file (using the Save method to export it to a file) for us to debug?

    Hello,







    The Radiobutton celltype will not get exported to Excel. The value stored in the cell containing the RadioButtonListCellType should be exported.

    Scott,

    Hello,







    I was able to reproduce this problem and have reported this as a bug (14582). The problem is in the call we are making to do a BinarySearch for the value in the cell in the arraylist of values for the celltype. It is not returning to us the expected value all the time. The development team is searching for a fix for this bug. For now, you can change your DataSet to use numbers (0,1,2,etc) to choose the correct radio button and then not set up a Values array for the celltype. This problem should be fixed in the next maintenance release.

    I have downloaded the latest release the problem does not seem to be fixed?

    Hello,







    With the 1.0.6.0 version of Spread for Web Forms, this problem should be fixed. I used the test project you sent me and with the 1.0.5.0 version of the Spread for Web Forms, I was able to reproduce the same problem you are seeing, but once I changed the project to use the 1.0.6.0 version, the Excel file exported correctly. What problems are you seeing when using the latest maintenance release?

    This exception means that you’re trying to access a collection item by index, using an invalid index. An index is invalid when it’s lower than the collection’s lower bound or greater than or equal to the number of elements it contains. Indexing an empty list will always throw an exception. Use a method like Add to append the item to the end of the list, or Insert to place the item in the middle of the list somewhere, etc. You cannot index into a c# list if that offset doesn’t exist. IndexOutOfRangeException exception is thrown as a result of developer error. Instead of handling the exception, you should diagnose the cause of the error and correct your code.

    Handling the Exception:

    Use for-each loop: This automatically handles indices while accessing the elements of an array.

    Use Try-Catch: Consider enclosing your code inside a try-catch statement and manipulate the exception accordingly. As mentioned, C# won’t let you access an invalid index and will definitely throw an IndexOutOfRangeException. However, we should be careful inside the block of the catch statement, because if we don’t handle the exception appropriately, we may conceal it and thus, create a bug in your application.
