As you ve seen, when the UpdatePanel performs its callback, the web page code runs in exactly the same way as if the page had been posted back. The only difference is the means of communication (the page uses an asynchronous call to get the new data) and the way the received data is dealt with (the UpdatePanel refreshes its inner content, but the remainder of the page is not changed). For that reason, you don t need to make significant changes to your server-side code or deal with new error conditions. That said, problems can occur when performing an asynchronous postback just as they do when performing a synchronous postback. To find out what happens, you can add code like this to the event handler for the Page.Load event, which causes an unhandled exception to occur when an asynchronous callback takes place: if (this.IsPostBack) { throw new ApplicationException("This operation failed."); } When the web page throws an unhandled exception, the error is caught by the ScriptManager and passed back to the client. The client-side JavaScript then throws a JavaScript error. What happens next depends on your browser settings, but usually browsers are configured to quietly suppress JavaScript errors. In Internet Explorer, an Error on page message appears in the status bar that indicates the

problem. If you double-click this notification, a dialog box appears with the full details, as shown in Figure 25-3.

VertexArray vertexArray = new VertexArray(vertices.length / 3, 3, 2); vertexArray.set(0, vertices.length/3, vertices); byte[] normals = { 0, 0, 127, 127, 0, 0, 0, -127, 0, };

Figure 25-3. Displaying a client-side message about a server-side error There s another option for dealing with the errors that occur during an asynchronous postback. You can use custom error pages, just as you do with ordinary web pages. All you need to do is add the <customErrors> element to the web.config file. For example, here s a <customErrors> element that redirects all errors to the page named ErrorPage.aspx: <configuration> <system.web> <customErrors defaultRedirect="ErrorPage.aspx" mode="On"></customErrors> ... </system.web> </configuration> Now, when the PageRequestManager is informed of an error it will redirect the browser to ErrorPage.aspx. It also adds an aspxerrorpath query string argument to the URL that indicates the URL of the page where the problem originated, as shown here: http://localhost/Ajax/ErrorPage.aspx aspxerrorpath=/Ajax/UpdatePanels.aspx You can write code in ErrorPage.aspx that reads the aspxerrorpath information. For example, you might include a button that redirects the user to the original requested page, like this:

protected void cmdOK_Click(Object sender, EventArgs e) { // Abort the event if the control isn't valid. if (!RangeValidator.IsValid) return; lblMessage.Text = "cmdOK_Click event handler executed."; } This code solves the current problem, but it isn t much help if the page contains multiple validation controls. Fortunately, every web form provides its own IsValid property. This property will be false if any validation control has failed. It will be true if all the validation controls completed successfully. If validation was not performed (for example, if the validation controls are disabled or if the button has CausesValidation set to false), you ll get an HttpException when you attempt to read the IsValid property. protected void cmdOK_Click(Object sender, EventArgs e) { // Abort the event if any control on the page is invalid. if (!Page.IsValid) return; lblMessage.Text = "cmdOK_Click event handler executed."; } Remember, client-side validation is just nice frosting on top of your application. Server-side validation will always be performed, ensuring that crafty users can t spoof pages.
