Try this as an example.

Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
    'Do NOT (ever) refer to form controls from this method
    'Keep it self contained

    'Add your background code

    'As you pass through each loop in your long runtime method do something like this
    BackgroundWorker1.ReportProgress(CInt((countsofar / totalofthingstodo) * 100))
End Sub
Private Sub BackgroundWorker1_ProgressChanged(ByVal sender As System.Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles BackgroundWorker1.ProgressChanged
    'Only ever refer to form controls from this method
    ProgressBar1.Value = e.ProgressPercentage
End Sub
Private Sub BackgroundWorker1_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted
    ProgressBar1.Value = ProgressBar1.Minimum
End Sub
Where it says ''Add your background code', use that to fill a DataSet (created programatically, not a form control) and once the background worker has finished you can attach the DataSet to the DataGridView.

Do the DataGridView Loading via a BackgroundWorker, you'll need to populate an object you create in the BackgroundWorker thread rather than the DGV directly (since you shouldn't interact with the UI thread from the BackgroundWorker thread) and then copy the data to the DGV when it finishes. Use something like this[^] as your progress bar and the ReportProgress functionality of the BackgroundWorker to update it to show progress and a message.
