I've got an app that does the following:
1) Load a DataTable with info
2) Attach the DataTable to the RadGridView
3) Runs a threaded, long process using a BackgroundWorker object.
4) Since it's using a separate thread, I update the rows with new information via the DataTable object using the row number as my identifier to know which row needs updating.
This is all fine until the GridView is grouped. If I group, then run the same process, the row number for the GridView has changed, but not for the DataTable object. How can I get them the same so I know which row to update?

Hello Robert Miles,
Thank you writing.
The described behavior is expected, because all data operations in RadGridView (such as sorting, filtering, grouping etc) lead to rearranging the grid's Rows collection, but not the data source's one.
Using the RowIndex is not a good practice, instead just save the reference of the particular row in the GridViewRowInfo object:
All the best,

I'm afraid that won't work. I have to update the DataTable object since I am using a BackgroundWorker thread. Since it's a separate thread, I can't do any operations on UI objects that were created in the main thread. I need to know its index in the DataTable.
Any other ideas?

Hello Robert Miles,
If you want a direct access to underling row's object, just take the bound datasource's object for the particular row through its DataBoundItem:
