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

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

asp:Button inside a SharePoint Dataview's Rows with onclick event does not call C# function. Pull i

asp:Button inside SharePoint Dataview Rows with onclick event does not call C# function. Pull it out of Dataview and works fine. I have a ASP.NET Button I've placed inside a SharePoint  DataView's rows with an onclick event pointing to C# function block inside my page. The page refreshes when I click on them, but it's not hitting that code block. If I move the button to outside the dataview and make the ID fixed, the code works beautifully. what's up with that? the button in the Dataview: td class="ms-vb" style="width: 70px"><asp:Button runat="server" Text="Delete" id="Delete{@ID}" CommandArgument="{@FileRef}" OnClick="DeleteDoc"/> </td> my C# onclick handler (inline C# on the page) void DeleteDoc(object sender, EventArgs e) { Button b = sender as Button; .. more code The buttons are rendered and they look like this: input type="submit" name="ctl00$PlaceHolderMain$g_08acadfd_957b_4112_a426_cc7c81991c1e$Delete1" value="Delete" id="ctl00_PlaceHolderMain_g_08acadfd_957b_4112_a426_cc7c81991c1e_Delete1" Thie code block in inline and I'm working from SharePoint Designer. Not sure how I can troubleshoot this.  Am I missing something here, maybe I need to add an Itemtemplate or something like we need to in the ASP.N
