private void combobox2_TextChanged(object sender, EventArgs e)
{
if (cmbDataSourceExtractor.IsBusy)
cmbDataSourceExtractor.CancelAsync();
var filledComboboxValues = new FilledComboboxValues{ V1 = combobox1.Text,
V2 = combobox2.Text};
cmbDataSourceExtractor.RunWorkerAsync(filledComboboxValues );
}
As far as building DataSource is time-consuming process (it creates a request to database and executes it) I decided that it's better to perform it in another process using BackgroundWorker. So there's a scenario when cmbDataSourceExtractor hasn't completed its work and the user types one more symbol. In this case I get an exception on this line
cmbDataSourceExtractor.RunWorkerAsync(filledComboboxValues );
about that BackgroundWorker is busy and cannot perform several actions in the same time.
How to get rid of this exception?
Thanks in advance!
