Allow RadGridVIew Exports to perform independently in BackgroundWorker without suspending UI thread of RadGridView.
In our Q2 2015 release we will introduce a new export option, which will perform the export operation in a separate thread. This new export functionality will improve the export performance and will also support cancellation and progress reporting.
Currently, we are not able to engage with a time frame when this functionality will be implemented. We prioritize the items according to their votes (and other criteria), so if you have not voted already, feel free to do so.
Its getting close to a year since I reported this issue, is this issue going to be corrected?
