I have the following code:
[Code]....
I am getting the following error:
System.NullReferenceException
Object reference not set to an instance of an object.
at ChooseTime_aspx.Page_Load(Object sender, EventArgs e)
at System.Web.UI.Control.OnLoad(EventArgs e)
at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
[Code]....
And the stack trace is as follows[Code]....I am not able to get what is the problem here?
I have a remoting-type set up within my application where I avoid TargetInvocationExceptions and grab the inner exception. I invoke the internal PrepForRemoting method on the Exception class to preserve the stack trace from the invoked method.
This appears to construct the stack trace property correctly:
[code]....
Calling Server.GetLastError(); on Application_Error in Global.asax shows the correct stack trace. Where is the yellow screen stack trace coming from?
RepeaterItemEventArgs e)
at System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource)
at System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e)
at _Default.up1_Load()
[code]...
is it happening in the Repeater1_ItemDataBound sub routine, or in the Timer1_Tick sub routine? Is the last thing that happened before the error occured at the top or bottom of the trace?
I have enabled trace in web.config which shows any error occur in my application on production by accessing trace.axd page. It shows very useful information.
My question is where trace.axd page retreive data so I can use some of the information on my gridview to organize it.
i have published asp.net mvc application on iis 6 on the server(windows server 2003) from local machine. On server i have set the default page to default.aspx. but when i try to browse the site on server, it gives me exception "The incoming request does not match any route" One thing i noticed is that. Stack trace on line 5 is shown below. it has one weird thing that exception is still pointing to my local machine path
[code]....
I am trying to redirect my trace output to a text file.
For this I tried to add a textwritertracelistener object to Trace.Listeners.Add but I can't see Listeners Class in Trace.ie When I put Trace. the Listeners class is not popup. Also I am unable to add System.Diagnostics.TraceListener namespace to the page.
My code is as given below ..

I am new to .net and wanted to know how to activate stack tracing in .net?
View 3 Repliesbased on a recent article on MySpace blaming the microsoft stack not being able to easily scale here.Is this true? Is scaling an app built on the microsoft stack (asp.net mvc here) nearly impossible? does php/LAMP really scale better than microsoft?
View 1 Replieswe are getting a stack overflow in production ~ 2-4 times / dayWe cannot reproduce this is in dev environment, nad given this is a web app with probably ~100 concurrent users at any one time, I'm struggling to work out how best to track this down.Is there anyway to get any more info from event viewer - happy to install some form of listener tool - even if i can just get teh thread identity (set to the current user) that'll help - although the dll + class / function woudl be great!

View 7 RepliesI'm using ASP.NET for a search app web site.My search retrieves exactly one result per fetch. Once the search is complete and the user selects "Update", a new result is fetched and the old result is written to the ViewState as a generic List. The new result replaces the old one.I am trying to get the page to update (via partial post-back), so that the old result drops down the screen and the new result sits on top of it. Much like the concept of a stack.

How can i solve this problem.
How would you implement a user message stack in ASP.Net MVC? (you set messages for the user in any place inside your app. and they are shown as hints of your app to the user anywhere inside the app)

Let's say I asked Microsoft to describe the perfect, modern, Microsoft-based technology stack to power a standard e-commerce web site, which perhaps has a simple 2-tier web/database architecture. What would it be like? Yes, I'm just looking for a list of product / technology names.
For example, in the J2EE world, I might describe a stack that includes:
J2EE 6 standard
JavaServer Faces
Glassfish 3
MySQL 5.1.x
I'm guessing this stack includes some combination of .NET, SQL Server, ASP.NET, IIS, etc. but I am not familiar with this world. Looking for ideas on the equivalent in Microsoft-land.
I'm looking for suggestions for the following issue, and I realize there is really not going to be a perfect answer to my question:I have a UI built in WinForms.NET (v4.0 framework) with WCF back-end and EF4 model objects, that I am looking to port to the web. UI is not huge and is not super complex and is structured well. But it is not a super simple system either. I am looking to pick a technology stack for the web-frontend that will target desktop & partially mobile platforms, provide a good development platform to build on, and facilitate code reuse across UI and back-end tiers...

I'm interested in creating "short URLs" a segment of pages on a site. However, this isn't in the traditional sense of "short URLs" like bit.ly where it will redirect to a different destination URL. I want the short URL to be the final destination.For example, one of these URLs might be http://foo/a/Afjbg, and when you navigate to it, it stays on http://foo/a/Afjbg (IOW, http://foo/a/Afjbg is visible to the user in the address bar).
If it was static content, I would just arrange the pages and folders into these names. But the content I will have on the site will be dynamically driven from a DB, so each page is generated on the fly. So the content looks logically different, but in reality is essentially the same .aspx page with dynamic content.How can this be accomplished on a Microsoft hosting stack? The platform is IIS 7 with ASP.NET 4.
i'm a total newbie with asp.net mvc and here's my jam:
i have a 3 level list box which selection on box A shows options on box B and selection on box B will show the options for box C.
I'm trying to do the whole thing in asp.net MVC and what i see is that the nerd dinner tutorial uses the ORM method.
so i created a dbml to the database and drag the stored proc inside. i create a datacontext object but i don't quite know how to connect the result from the stored proce which should be multiple rows of data and make it into a json. so i can keep all the json data inside the html page and using jquery i could make the selection process faster. i don't expect the data inside the three boxes to change so often thus i think this method should be quite viable.
Questions:
So how do i get the stored proc part
to return the data as json?
i've noticed some tutorial online
that the json return result part is
at the controller and not at the
model end.
Why is that?
Edit
FYI, i find what i mostly wanted to do here.
For the json part, i referenced here.
