javascript error with pagination and sorting

[Emanuele]

Hi, I have a problematic situation with a grid bounded to a datasource at runtime.
If I work on the grid only with command buttons by editing then it works by reloading the data with the DataBind method.
If I try to order or change page a javascript exception is thrown:

Exception at row 1, column 123034 in http://localhost:55112/bundles/MsAjaxJs?v=c42ygB2U07n37m_Sfa8ZbLGVu4Rr2gsBo7MvUEnJeZ81
0x800a139e - Javascript run-time error: Sys.WebForms.PageRequestManagerServerErrorException: Index is outside the range. Non-negative value and requires less the size of the collection.

See the attach files for details (is a zip)

Thanks a lot

Hello Emanuele,

I have examined your implementation and I have noticed that you are binding the grid through the DataSourceID property, with Simple Data-Binding and Advanced Data-Binding at the same time. Please note that this is not supported scenario and you will have to choose one of those approaches in order to allow the RadGrid to work properly.

If you are going to use complex operations like paging, filtering, editing, sorting, etc., you need to use the Advanced Data-Binding by handling the OnNeedDataSource event only.

Please modify your code accordingly and see if the issue will be resolved.

Hi Konstantin, i've modified code deleting DataSourceID assignment in RadGrid and MasterTableView.

Unfortunately the error has not disappeared.

If i launch the release version i can see in the js console (IE) this message on the order action:
SCRIPT5007: Unable to retrieve the 'PRM_ServerError' property of a null or undefined reference
File: RichiesteReg, riga: 1, colonna: 118032
