SafeGuardUpdate Property

Gets or sets a value indicating whether to safe guard the code block that applies the new output after a callback.

Syntax
C#
Copy
 public Boolean SafeGuardUpdate { get; set; }
Remarks

EO.Web CallbackPanel executes embedded JavaScript code rendered by user code during the callback. In case there is an error in the user code, CallbackPanel can either handle it and continue its normal flow or do nothing.

By default SafeGuardUpdate is set to true, which means the CallbackPanel will handle the error and continue its normal flow. In this case the end user will get a message box displaying the error message if Runtime.DebugLevel is set to a value higher than zero. The message box will not be displayed if Runtime.DebugLevel is set to zero.

Setting SafeGuardUpdate to false allows the debugger to catch the exact location of the error but risking of destroying the internal states of the CallbackPanel control thus making it unable to handle further callback request. As such this property should only be used as a debug tool.
