Namespace Removed In Web.config Not Removed In A Page With Master?

Sep 12, 2010

I have defined this in the web.config of a subdirectory

<remove namespace="App"/>
<add namespace="Tom"/>

App is imported in the parent web.config file, Tom and App have classes with the same names.To avoid errors resulting from ambiguous class names I removed the App namespace from the sub-directory where the Tom namespace is used.

However the namespace App is still imported on content pages that have a master page outside the Tom directory. This causes the aforementioned errors.Here is my dir structure

-Root Directory
--web.config (App is added in web.config)
--Tom Sub-diretory
---web.config (App is removed in web.config)
---Content page that uses Default.master (Here is the problem)
---Page without master (Works OK)

Why Isn't The Last Row In A Repeater Get Removed

Nov 10, 2010

I have a ASP .NET Repeater data bound to a DataTable. Everything works fine where I can add rows to the DataTable & Bind() and the Repeater will gracefully show the newly bound data and delete from the DataTable and Bind() and the Repeater will remove the data.

However a strange problem exists where when rows are been deleted, the last standing row, although perfectly deleted from the DataTable would still be shown in the web page. It's as if for the last row, the Repeater is not data bound! But I have put break points and analysed that the item is definitely deleted from the DataTable and the Repeater1.DataBound() is called as well. If the page is refreshed, the last item is deleted as well (just as it should).

if (dtTelephoneNumbers.Rows.Count == 0)

Here is my delete code.


public static DataTable dtTelephoneNumbers = new DataTable();

And everything happens inside a UpdatePanel which is inside a Wizard Step.


The data is local only (for now). I collect all information from the user using a wizard and finally add it to the database.


Works just fine when used without an UpdatePanel. :( Looks like the UpdatePanel has got something to do with this!

When Publishing A Website Default Document Name Keeps Getting Removed From IIS

Nov 7, 2010

I have an ASP.NET web site project, which I'm publishing to IIS on my Win2k8 R2 server. It has a default page called login.aspx. I set that up on the published web site.

Trouble is, every time I publish a new version of the web site, the login.aspx entry gets erased from the "Default Document" settings of the web site in IIS. This is very annoying. How can I publish my web site from Visual Studio without wiping out the default page every time?

I have a form that has contact fields, billing address, and shipping address.

Forms Data Controls :: AlternateRowStyle When Row Is Removed?

Jun 30, 2010

I have a GridView that has a RowStyleColor which is White and an AlternatingRowStyleColor which is a light blue.

I am having an issue where under certain cases a row with will be hidden if a cell contains a certain value and this causes issues with my row styles.

I though by adding the row styles during the RowDataBound event, this would resolve my issue:


Unfortunately, this does not seem to have any effect and I get the same results as if I were to add the row styles in the .ASPX page.

Session Objects Are Not Removed After Timeout Period?

Feb 8, 2011

Why Session objects are not removed after Timeout period?

I am using Asp.Net 4.0 and Session state is configured as shown below.

<sessionState mode="SQLServer" cookieless="false" timeout="5"
sqlConnectionString="data source=.SqlExpress;initial catalog=App_SessionState;user id=sa;password=xxxxxxxx"/>

If I have not activity in browser for about 10 mins, shouldn't the Session object be removed. But after 10 mins I can still access the Session variable. Am I missing something here?


If I access a session variable after 10 mins as shown below shouldn't I get NULL

var myObj = Session["MyKey"] as MyClass;
mObj is not NULL after 10 mins.

How To Create A Submitable Form That Contains Dynamically Added And Removed Controls

May 20, 2010

I am trying to create a form that is made up of controls with values that represent an entity with multiple child entities.

The form will represent a product with multiple properties where the user will then be able to create options with multiple properties which in turn be able to create multiple option-items with multiple properties.

My question is what is the best approach? Can i use ajax to avoid postbacks and having to rewrite the controls to the page? If i dynamically add the controls in the form of table rows or grid rows will the data/control values be available in the code-behind when i submit?

This is an age old question.. the last time i had to do this was .Net 2.0, pre-ajax (for me) and i was forced to recreate all the controls on each post back.
