Hello.  I am trying to solve the problem of keeping our data fresh using the Telerik WPF RadGridView.  I know that Telerik loads an in-memory copy of the collection that it binds to, but is there a way to keep it fresh?  We have a grid that queries 45,000 records.  Currently we have it working with a plain old windows grid by laoding in a page size at a time of records.  Because it goes back to the database each time we click the page buttons or do a sort or filter, the data stays fresh.  On the other hand, I also have a Telerik grid that queries the same set of records, but since it does not go back to the database for page operations and sorting and filtering, it gets stale data.  I verified this by updating some of the database fields and observing the old values instead of new ones.  Our work environment demands that the data be as fresh as possible (not just for insertion and deletion of records but for updating of existing records).  We have kicked around several ideas such as a refresh button, having a timer that goes back to the database to load every 15 minutes, or doing a database pull each time that the user does a paging, sort, or filter operation.  However, I am having a hard time finding the event in the RadGridPager that will let me make this call in the view model.  Is it even exposed?  Keep in mind that we are using MVVM, so I can use code behind if needed, but I would like to avoid that if possible.  Thank you.
