Application_error not firing

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :ASP.Net
I have included code in the Application_Error event of my global.asax file. Unfortunately it appears that this event is not firing. If I try to handle the event in web.config it works fine. Q. Do I need to set custom errors mode to 'off' in web.config in order for Application_Error to handle the error. If not any ideas why Applicaiton_Error is not running it's code?

MouseUp event not firing on ActivityDesigner class?

I have a custom control derived from ActivityDesigner.  I'm basically retemplating the contol to give it a stylized look and feel ... I want to add the ability to change the Display Name by swapping out the TextBlock with a TextBox on MouseUP - but this event is not firing. I can handle the MouseDown event and it works OK, except it enters the Edit mode when dragging the activity around.  Is the MouseUp handled at the base level?  Is there a way to work around this? 

Scripting tags not firing

This should be so simple but the answer is escaping me.  We have a simple ASP.NET 3.5 webform written in VB.  The form does not contain any databound controls.  The markup posted below is a simplified version of the page.  We're trying to get the script code in the Text property of the label to fire.  I seem to recall there is something that needs to be put in the Page_Load to force the scripting to run under these circumstances but I can't recall what it is.  Can someone help please?<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Test2.aspx.vb" Inherits="EUCNET00123.Test2" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:Label ID="Label33" runat="server" Text='<%= IIf(String.IsNullOrEmpty("X"), "Null or Empty", "Not Empty") %>'> </asp:Label> </div> </form> </body> </html&g

HTTPModule Events not firing for non-administrative user

Hi All, I have deployed an HTTP module into the GAC on MOSS 2007 and Win 2k8. When I log in as administrator to the site, everything works fine.

IsVisibleChanged not firing when element is in collapsed parent element

Using the code below, it is possible to change the child grid's visibility in code-behind. However, as long as the parent grid is collapsed, the IsVisibleChanged event will not fire for the child grid even though its visibility actually changes. Is this by design, or am I missing something? I want to be able to change the parent grid's visibility when the child grid's visibility changes, and under these circumstances I have to work around the issue with the non-firing event. <Grid x:Name="LayoutRoot">   <Grid x:Name="grdOuterGrid" Visibility="Collapsed">     <Grid x:Name="grdInnerGrid" IsVisibleChanged="grdInnerGrid_IsVisibleChanged" />   </Grid> </Grid>

RowCommand not firing inside a GridView

Hello,  I'm trying to fire the RowCommand event on a DataGrid control.  I've previously done that, but not in this precise case.  Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary. The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.   Basically I have a GridView which I bind to a DataSet.  According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).  By pushing this button, I want to show a second GridView containing those details.  Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.   The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')".  When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!   In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.   Here's my summarized problem and

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?
