Aspxgridview rowupdating error message
In your case, your service intercepts exceptions and writes some error codes as a response.
A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.
then the Custom Error event will not fire, will it ?
What I want to do is to react on everything else than Error Code.
And moreover, your code will forward the exception to the IIS (which shows a page with an error description).
When the exception occurs during a callback, our controls (they process callbacks by themselves) catch (via try...catch block) and show them in the Error Row.
