Redirection on a Callback Error
When any server error occurs during server-side callback processing, ASPxHttpHandlerModule prevents an application from remaining pending, by composing and sending a specific response to the client. To redirect the response to a specific page, you can use this callbackErrorRedirectUrl option within the Web.Config file, specifying the required page name.
Declaration
<configuration>
...
<devExpress>
...
<errors callbackErrorRedirectUrl="" />
</devExpress>
...
</configuration>
Note
You should register the DevExpress Web.config section to apply these settings to your project.
By default, this option’s value is an empty string. Assign a value to this option (for instance as callbackErrorRedirectUrl=”Default2.aspx”) to specify the redirection location.
