Overview
The ErrorProvider control is functionally equivialent to the Windows Forms ErrorProvider control. It provides a very simple means of notifying the user about errors on their forms, by showing an error icon with a tooltip.
The ErrorProvider can be used in three flavors, so to speak:
- One ErrorProvider control on the whole form
- One ErrorProvider control for each control on the form
- Watching for errors on a Datasource implementing the IList interface
The ErrorProvider does not come with any UI component itself, so you do not add the control to the Form's Controls container.
Availability
The ErrorProvicer is one of the Out of the Box standard controls, which means it is free and available in all Visual WebGui versions.
