How to: Specify Layout for In-Place Messages On ASP.NET Server Controls
When an ASP.NET validation error message appears on the page, it becomes part of the layout of the page. You can specify that the layout be fixed—the error message does not change the page layout when it appears—or dynamic. For details about layout options, see Validation Error Message Layout for ASP.NET Server Controls.
To specify fixed or dynamic layout for client error messages
Set the Display property of each validation control to one of the following values from the ValidatorDisplay enumeration:
Option Description Used when you are using only the summary control
For a fixed layout
For a dynamic layout
Note A browser that supports dynamic HTML (DHTML) is necessary to view static layout.
