DataLoadingError Class
An error occurred during loading data to a data source.
Namespace: DevExpress.DashboardCommon
Assembly: DevExpress.Dashboard.v24.2.Core.dll
Declaration
Remarks
The DataLoadingError object is a container for the information related to the data loading error:
- data source name
- an exception that occurs during data loading
- the text to explain the situation to the end user.
The DataLoadingError objects are available in the DataLoadingError event handlers.
The DataLoadingError events (e.g., DashboardDesigner.DataLoadingError, DashboardViewer.DataLoadingError, or DashboardControl.DataLoadingError) are raised when one or more errors occur during data loading. The Error dialog informs the end user about these errors:
In code, use the DataLoadingErrorEventArgs.Errors property to obtain a list of DataLoadingError instances.
Tip
To hide the Error dialog, set the DataLoadingErrorEventArgs.Handled property to true.
Note
To handle connection errors, subscribe to the ConnectionError events.
