Parameters
- e
- Type: System.Web.UI::AsyncPostBackErrorEventArgs
The error event data.
The AsyncPostBackError event is raised when there is a page error during asynchronous postbacks. How errors on the server are sent to the client depends on the AllowCustomErrorsRedirect property, the AsyncPostBackErrorMessage property, and the custom errors section of the Web.config file.
The following example shows how to handle the AsyncPostBackError event to set the AsyncPostBackErrorMessage property (which is sent to the client) to the server exception error message.
