Mac os rapidclick5/9/2023 My page that errors has a GridView bound to an ObjectDataSource. I can confirm I get exactly the same error. I'm sure other developers are also hit, aren't they? special remark:Īlthough we have NO webfarm in use, i've also tried to use a self-generated in web.config. no success as expected -) ![]() Message "Validation of viewstate MAC failed" occurs in simple page architecture (no masterpages, no callbacks etc.) even! and we've figured out that all our asp.net applications (which were running fine in asp.net beta 2.0) have this problem :-( error i'm working in a small developping team for web solutions. My problem has too be a general one in asp.net 2.0 final framework. Navigate too quickly (have a look at first post for its explanation). they fail in both cases (bound / unbound) if you and it does not even matter if they are bound to a datasource control. Gridview, a detailview or a formview within the *.aspx page. my reported problem only occurs if you've nested a I've done a lot of test cases in recently past hours, following i found out concerning my problem: it depends on which webcontrols you have in use in an asp.net 2.0 final application. Unfortunately there's no "perfect" solution for this just yet. Of course, that's hard to tell your users, but perhaps you couldĭisable the UI until the form has rendered? Alternatively, just never post back before the form has finished rendering. One work around is of course to just disable event validation, but you have to be aware of the security implications. If you submit a form before it has been entirely rendered, then chances are the EventValidation field has not yet been rendered, and thus ASP.net cannot validate your click. If EventValidation is enabled (which it is, by default), but ASP.net doesn't see the hidden field when you postback, you also get the exception. The problem you're seeing happens specifically when you postback before the EventValidation field has been rendered. If it's not valid, you get the exception that you've been seeing. When a postback occurs, ASP.net uses the values stored in this hidden field to ensure that the button you clicked invokes a valid event. The end result is that at the bottom of your rendered tag, you'll see something like this: This feature is implemented by having controls register valid events when they render (as in, during their actual Render() methods). This is a security feature that ensures that postback actions only come from events allowed and created by the server to help prevent The error that's happening (as has been mentioned earlier) is caused by an ASP.net 2.0 feature called Event Validation. Is there also a solution available for asp.net 2.0 final version? The second error could be solved with hotfixes/updates in asp.net 1.0/1.1 The state information is invalid for this page and might be corrupted. page property "EnableViewStateMac" set to false does not solve the problem, it just changes the error message I've read a lot of articles and forum posts, and nothing figured out the problem: Whole page has finished rendering, then the postback generates no errors. that means, if you press an before the whole page is loaded/rendered, then you get this posted error. This error is only generated if you navigate quickly through the web application. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. now, with the new asp.net 2.0 final version, i'm getting a lot this error message: it compiled and ran without any problems. I developped a "job search application" in asp.net 2.0 beta. Thanks in advance, I'll try and be responsive to any questions you may have.Maybe you can help me with the following prob: I would also like source files for the design (psd, ai etc.) Icon should look great as a standard Mac OS X icon at 512x512 and scale down well to smaller sizes too. ![]() The app's UI is red and black/grey (see attached pictures) so perhaps those colours could be used. You can also try it for yourself here (needs Mac OS X 10.6): You can see a video of the app in action here: ![]() or some other concept, these are just ideas. some kind of 'clicking machine', a contraption with wheels and levers Here are a few ideas for elements that could make a memorable icon: Something that represents the slightly quirky nature of the app. I'd like something pictorial and creative, slightly unusual. I'm looking for something fairly fun which appeals to the eye and conveys the idea of rapid clicking. ![]() Especially users of games such as FarmVille which need lots of clicking (all that harvesting crops)! It's useful for anyone who needs to click the mouse a lot and doesn't want tired hands. It is a simple app that rapidly clicks the mouse up to 10 times per second. I need an icon for my new application, RapidClick.
