Button click event handler firing twice

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net
I noticed today that button click event handlers are firing twice for me in some cases when the button is inside an UpdatePanel -- but only in Firefox.  I'm wondering if this might have to do with the Firefox update that came out today because I never noticed this problem until today.  Has anyone else run into this problem?

OK button click on Windows dialogue form not triggering click event

I have created an Add-In for Outlook 2003 in Visual Studio 2005. When a new message is sent and a toggle button is selected, a form that I have created will be displayed as a dialogue box, where further information can be entered. Once this information has been entered you can click the OK button and the message is sent. If you were to click the OK button with invalid data in the form, there would be a message box with an error message. This all works perfectly on my development machine but when I have packaged the Add-In and installed it on other machines it does not work. Clicking on the OK button does nothing, there is not even an error message. All the prerequsits are successfully installed and this is the only part of the Add-In that does not work. All help greatly appreciated. Thanks Nick

Sharepoint Event Handler not firing

I have written an event handler for an ItemAdded eventfor a document library. I am trying to read an excel file being uploaded and extract a value from it which I write to a list column for the item. I have this working properly on my development machine which is a Windows Server 2003 machine.However, on a production Windows Server 2008 machine, the event handler never fires. I am doing a simple write to a log file to test and see if it runs at all even if the Excel parsing does not work but I get no indication that it ran. The event handler is being registered with a feature that I am deploying. I have verified that the event handler is registered to the library by using the u2u Event Handler Explorer tool.Is there any way I can determine if my event handlers are even executing? How can I debug this?

Viewstate issue when calling button click event from Javascript

I have a javascript that asks a confirmation on search click. If the user has made some changes to the data in grid (gridview) on click of Search, a confirmation is asked to Save or Continue Search. If Yes, Save the records by invoking Save click from javascript. If No, Search click is invoked. While Search click happens correctly, Save click results in an error which reads like this..  "Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. " I know the Viewstate is what causing the problem, where the control is not loaded but script is trying to invoke it's click event. Any help is appreciated. At the end of the day, all i need is to invoke Save click from javascript.   -- Viswanth VG
