RadBusyindicator Freezes when exporting RadGridView to Excel File
Environment

| Product | RadBusyIndicator for WPF |
Description
RadBusyindicator freezes while RadGridView export is running.
Solution
To minimize this, separate the creating of the document model from the saving of the file. Saving of the file can be executed on a separate thread. Also, use the ExportToWorkbook() method for creating the document model.
private BackgroundWorker backgroundWorker;
private Stream documentStream;
private void ExportToXlsX(RadGridView gridView)
{
SaveFileDialog dialog = new SaveFileDialog()
{
DefaultExt = "xlsx",
Filter = String.Format("Workbooks (.{0})|.{0}|All files (.)|.", "xlsx"),
FilterIndex = 1
};
if (dialog.ShowDialog() == true)
{
var document = gridView.ExportToWorkbook(new GridViewDocumentExportOptions()
{
ShowColumnFooters = true,
ShowColumnHeaders = true,
ShowGroupFooters = true
});
this.documentStream = dialog.OpenFile();
var backgroundWorker = new BackgroundWorker();
backgroundWorker.DoWork += BackgroundWorker_DoWork;
this.radBusyIndicator.IsBusy = true;
backgroundWorker.RunWorkerAsync(document);
}
}
private void BackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
var formatProvider = new XlsxFormatProvider();
formatProvider.Export((Workbook)e.Argument, this.documentStream);
this.documentStream.Close();
App.Current.Dispatcher.BeginInvoke(new Action(() =>
{
this.radBusyIndicator.IsBusy = false;
}));
}
