Currently I am working with a RadGrid that is using batch update that is attached to a SqlDataSoure to load, update and delete. Everything is working fine but normally the users spend around 20 minutes to review and update everything they need before hit "Save Changes", during this process new records are inserted in the database so the data displayed on the screen is not the same of the database. When the user finally hit "Save Changes" the grid refresh first the dataset and after that perform the updates generating errors because records that were not displayed are updated.
Is there a way to tell the grid to load the data only when it is not postback? Like doing it in the OnNeedDatasource in the code behind.

Hi,
I suppose that the grid throw errors because the data was edited by someone else before the other user click Save Changes. This is not related to the grid itself, if you use ASP GridView you will encounter the same problem. However, to prevent this exceptions you can handle edit process manually. To complete this you can use OnBatchEditCommand event and conditionally update the datasource.
