Hi,

I was trying to get ExcelML based export working. I was able to achieve some formatting and other Goals using ExcelML but as for ExcelML based export we need to implement Advanced databinding using NeedDataSource event, I had to do some changes to my existing code - which i did.
The problem I am facing now after doing all the changes is:

Page data source is changing as per requirement but page is not showing changed data. It's staying one step back. Here is scenario:

1. Page has a drop down with 3 types, suppose A, B and C.
2. First time page shows data depending upon the selection which is A.
3. I change selection to B. Page posts back, datatable is re-built and Grid's dataSource is Set to it but not ReBinded (as stated by Telerik). Page is still showing data shown previously i.e. data for type A.
4. I change selection to C. Page posts back, datatable is re-built and Grid's dataSource is Set to it but not ReBinded. Now page shows data for type B - which was selected in step 3.
5. If you keep changing the selection. Page shows data for previous type i.e. one step previous. Please note that datasource is built and set properly but page's view is not updated.

I tried rebinding the Grid and it some times works properly but it crashes other times. what to do? Any help?

Thanks.
