Gets or sets a value that determines whether the custom errors section of the Web.config file is used during an error in an asynchronous postback.

Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public bool AllowCustomErrorsRedirect { get; set; }
<asp:ScriptManager AllowCustomErrorsRedirect="True|False" />

Property Value

Type: System.Boolean
true if the custom errors setting in the Web.config file is used to determine error behavior during asynchronous postbacks; otherwise, false. The default is true.

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.
