Suppose that both FirstModule and SecondModule handle the Application_BeginRequest event. Will it execute in the order defined in the web.config?
<httpModules>
<add type="MyApp.FirstModule, MyApp" name="FirstModule"/>
<add type="MyApp.SecondModule, MyApp" name="SecondModule"/>
<add type="OtherApp.OtherModule, OtherApp" name="OtherModule"/>
</httpModules>
Are there other ways that the order can be specified?
MSDN got a page showing in which order ASP.Net global.asax methods are invoked. I can't seem to find it, anyone got a linkAre there a similar page, but for ASP.Net MVC (including in which order all controller methods are invoked like OnActionExecuting, OnAuthorization etc)?
ASP.Net app life cycle: http://msdn.microsoft.com/en-us/library/bb470252.aspx
Does the order of httpmodule execution match their order in the web.config or is it undefinied?
View 1 RepliesDuring a recent interview the following question was asked.
- A Master page which contains
- An ASPX web form page which contains
- A Web User Control inside the page which contains
- A button to fire some code in a button_click event
The Init Event will fire (Inner Most to Outer Most)
aspx.page Begin Init
-> Inside user control Page_Init
-> Inside master page Page_Init
-> Inside lifecycle page Page_Init
aspx.page End Init
and Load Event will fire
aspx.page Begin Load
-> Inside lifecycle page Page_Load
-> Inside master page Page_Load
-> Inside user control Page_Load
aspx.page End Load
Why does ASP.NET framework support different execution order in Load() and Init().This was the question asked in interview.I have no idea about what the interviewer expecting from me.
I have a list of methods I wish to call and a button accompaning each and a generic method to handle the buttons.Using the commandArgument how can I run the selected method.E.g. Click run method1 button. In handler for button click call the method as named in commandArgument
View 4 Repliesi know how to implement this thing..
but i have few question like..
wot is the major purpose of using HttpHandler & HttpModules..
and how they work with page life cycle..?did they get executed b4 page life cycle..?where i got more control and more power
in order to utilize HttpHandler & HttpModules..
When exactly to use HttpHandlers and HttpModules?Can't I write that code in ASPX pages' code behind?
View 1 RepliesI have a Gridview with a templated column which contains just a label.
I set the Label1.text during GridView1.RowDataBound based on doing a DataBinder.Eval(e.Row.DataItem,"myColumn") and a calculation off that.
When the user clicks the header I want it to sort based on what's in the Label but instead if seems to be sorting on the contents it was bound to, "myColumn", even though that's not what appears in the grid.

It works grate on my PC running XP and IIS 5.1
but on my webserver running IIS7 and WS 2008 dosn't works.
I recently started learning about HttpModules and made my first one. I was wondering if someone could explain why some modules in the the web.config include a lot of extra info and others do not.
example: not much info
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
example a lot of info
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
What is a publickeytoken, version, culture. Do I need to do anything special to use those?
I'd like to clean up the web.config and remove unneeded XML.
A default ASP.NET 3.5 web application has the follow elements in the web.config:
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/>
</httpHandlers>
<httpModules>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</httpModules>
When running under IIS7, which has modules and handlers being registered under the system.webServer element, is the configuration above still needed?
I attempted to find any information in regards to best practices of handling errors inside of a HttpModule unfortunately I can't seem to find any information on Google in regards to this.
All the information I've found all pertains in how to use the global.asax or a custom http module to log errors which is completely not pertinent.
Edit: Clearly this question has been misunderstood. I am seeking information regarding software patterns that are employed to prevent a HttpModules from faulting, triggering custom errors redirection, and faulting again causing infinite exception chains until IIS shuts down the thread entirely.
This however is very nontrivial since the HttpSessionState collection can't be depended on for the life cycle of HttpModules. Since error conditions have already occurred it would be improper to expect that I could read the ASP.NET session cookie to get an identifier that I could store user specific data in the application cache. Storing data in the HttpRequest.Items collection would be pointless since that in no way exists across multiple requests.
I have 5 hard corded texboxes in a page in a sequence with sequence Number .

Is there any way to set the width of a GridView to a pre-determined width?
I have set the width of the gridview and all the columns to a % and then to a number of pixels but it does work. The gridview always sets itself to a width required to display all fields and it goes beyond the resolution of the screen. I would like to contain it to 1024 pixels.
Here's my .aspx

From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

My task is to create an ASP.NET application with a piece of code which will automatically run every half an hour. This code must append a record to the file every half an hour. It should not depend on users requests(whether they happen or not).
1) I'm writing my code in Application.Start method of Global.asax file. Am I right?
2) Do I have anything to do with the hosting (IIS) settings (e.g. change permissions to write the file, etc)?
I have already tried just putting the code to write to file into a loop in Application.Start method and then just copied the project directory to the server. However, it didn't work.
