An error occurred during loading data to a data source.
The DataLoadingError events (e.g., DashboardDesigner.DataLoadingError or DashboardViewer.DataLoadingError) are raised when one or more errors occur during data loading. The following form lists these errors.
You can obtain the list of errors using the DataLoadingErrorEventArgs.Errors event parameter, which returns the list of DataLoadingError instances. To suppress the form, set the DataLoadingErrorEventArgs.Handled property to true.
To handle connection errors, use the ConnectionError events.
