Description

  1. JVCLInfo

Use an error indicator when you need to notify the user about an erroneous input value in a non-intrusive way. The error indicator uses the real estate of the form or dialog to display icons next to each control that has been determined to have an error. The icons Hint is also assigned the specific error message so when the user moves the mouse over the icon, the reason for the error is displayed. Although mainly used to display erroneous user input, this component can be used whenever you want to draw the users attention to a specific control or set of controls without having to show a dialog or similar. This component was inspired by and roughly equivalent to the ErrorProvider component in .Net.
