ASP.NET Architecture - ASP.NET Worker Process - HTTP Pipleline - Http Modules and Handlers

"ASP.NET is a powerful platform for building Web applications, that provides a tremendous amount of flexibility and power for building just about any kind of Web application. Most people are familiar only with the high level frameworks like WebForms and WebServices which sit at the very top level of the ASP.NET hierarchy. In this article I'll describe the lower level aspects of ASP.NET and explain how requests move from Web Server to the ASP.NET runtime and then through the ASP.NET Http Pipeline to process requests.

Writing Http Handlers and Modules in IIS 7.5

This article describes how Http modules and handlers are to be written and configured in IIS 7.5. The concept of a handler and module remains same, so dose there programming model. In this section we start off with the concept of a Http module and a Http handler, then talk about how to code them and finally describe the two methods available to configure them.

Http Modules and the Http handlers in asp.net 4


I am using IIS 7 .when I tried to migrate  to asp.net 4 , the VS 2010  has removed the following tag on conversion .if I opened a web application  in 3.5 framework ,the following tag is added inside the Web.config file ,if i opened a asp.net4 application  the following tag is not added.

<validation validateIntegratedModeConfiguration="true" />

I know this tag is basically used when the application is running under the  Integrated mode.

Is this tag is required in asp.net 4 .Do we still need to configure the Http Modules and the Http handlers under the sytem.webserver in the Web.config?

Any suggestions are welcome

Tooltip for GridView Column Headers (ASP.Net)

I just wanted to add auto tooltips for my GridView headers. There are couple of ways but I don't want to use javascript and wanted to use simple 'title' attribute. It took couple of hours to get the working code supporting sortable columns. I thought it will be very useful for others. Here's the code and logic behind it.

Multiple Column Dropdownlist for the ASP.NET DataGrid

Based on my previous control "Multiple Column DropDownList for ASP.NET", I received many emails asking for the same control to be used in the DataGrid for web applications. Here we go.. This control can be used as the regular MS DropDownList in the DataGrid and also as a regular dropdownlist. It has all the properties, like DataTextField, DataValueField, DataSource, SelectedIndex etc. The download file contains the samples both in VB.NET and C#. In this sample, I have used the Northwind database of SQL Server.

Alternating row background for first column of a report


is there a way to make the first column of a report use the an alternating background color? 

I have the background color set for the entire row however it does not work for the first column if the color is set to an expression.  If I just set it to a color i.e. red it works just fine. If I insert a dummy column to the left it works just fine (but the dummy column does not work, presumably because it is first??).

In the file below only the textbox for part number does not show an alternating background.  All others work correctly.

                    <Textbox Name="PartNumber">

Use a column as parameter for a sds in another column; gridview


Hola, I have a gridview which is bound to a sds which returns 7 columns and I added two columns from the GUI.  What I want is to fill up the 9th column with DDLs and these  DDLS will get their data from a different sds which is using a stored procedure with a single parameter.  I created the 9th row, used template field, made the sds for 9th row, the stored_procedure, threw a DDL in Item template and all  I need now is to pass a parameter in the first column to the sds in the 9th column.  I can code this but i'm getting tired of aspx.cs :) and would like to do it from the GUI.

Pass a grid column value to a Modal


Hi, I have a requirement to hide a field called details on a gridview and show it in a jQuery modal dialog when users click on the Customer ID hyperlink. This grid is created programmatically. I will be hiding the details column via the CSS display:none property. Does some one know how can I pass the grid's selected hidden column value to the modal? Here is some of the code I started:

            GridView mygrid = new GridView();
            //.....................................More columns code for the grid

            //Here is where I need to pass the Details column value associated with the customer ID field selected to the Modal and open the Modal dialog.            
            HyperLinkField linkField = new HyperLinkField();
            string[] dataNavigateUrlFields = { "CustomerID" };
            linkField.DataTextField = "CustomerID";

HTTP Error 403 - Forbidden


(VB Express website directed me to ASP.NET Web Services which in turn redirected me to this forum).

 Hopefully someone can help me here...... 

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

What's up?????



Bug: Does not change column type from nvarchar to ntext


Scenario: If you create a table with a column of type nvarchar, populate it with some content and try to modify it using the WebMatrix editor, from nvarchar to ntext, it does not display any error message or warning that this is not possible. It silently saves and reverts the change, back to nvarchar. Wasted some hours on this issue as I thought my column was ntext, but in fact was still nvarchar.

Expected behavior: It should change to ntext, or if SQL CE doesn't support that, it should notify the user that no change was applied.

Display column from child table. Possible ?



I'am using dnamic entity with EF4. On a list page of a table, I would like to display a column containing information from a child table of the current element. Sample :

Order List :

Order Data | Required Date | Shipped Date | etc... | ... | Customer Name (foreign key with tostring() method override) | Customer Postal Code (Column that I want to add) |

I don't known how to do that. Is it possible ? Maybe I have to to create my own Metadata proxy that will add dynamicly a column on the MetaColumn list of the table.

Does someone have an easier or better idea ?

Thank you for any help.

Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

Filter by Computed Column



After looking for a driver to open legacy dbf drivers to connect, the next level trouble a have is this one:

first, i can retrieve the data but when trying to filter by a parameter (somesc columns) i get an error.

The error says about the database can't determine some blah blah!

The error is a columm tha is formated (  1234  ) about  8 space, fixed. The values in the query appears like that. I resolve this by Trimming Ltrim(ColumnName) and i get this (1234).

Now in SqlExpress, how can i filter by the new Trimmed Expression? (This is a primary key that the DBF use)


SELECT column1, column2, column3


SELECT Ltrim(column1) as NewExp, column2, column3
Where NewExpre = @NewExpres                  -Error-
