Dynamically add class to div with FileInfo

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :ASP.Net
Hey all. I'm still really new to this, so I apologize if I explain my problem poorly. I'll do my best.   I used this method to add an "active" class to my main navigation on another site.  Now I'm using it to change the background image for a div based on the current page. Problem is, it's not working in this case. When I view the source I just see the tag sitting sitting there like it wasn't compiled:  <div class="CategoryDetail <%= background %>" id="ctl00_ctl00_MainContent_uxCategory_cat_detail"> Here's the code behind:using System; using System.Collections.Generic; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using ZNode.Libraries.Framework.Business; using ZNode.Libraries.ECommerce.Catalog; using ZNode.Libraries.DataAccess.Custom; public partial class Themes_Default_Category_Category : System.Web.UI.UserControl { public string background; protected void Page_Load(object sender, EventArgs e) { System.IO.FileInfo fi = new System.IO.FileInfo(System.Web.HttpContext.Current.Request.Url.AbsolutePath); switch (fi.Name)

Dynamically Generate a WCF Proxy class at runtime and Callling web methods via reflection



I'm busy writing an application where the user will have to specify the location of a ?wsdl file for asmx and/or svc type services.

My application will have to :

1. Deduce from the wsdl what methods (with parameters and return types) are available on the service.

2. Provide a way to either generate a Proxy class in memory to execute methods against with e.g: Reflection

    for instanse : genericProxy.Invoke("HelloWorldMethod",parameter1,parameter2);

    I want to avoid using something like this : notSoGenericProxy.HelloWorldMethod(parameter1,parameter2); seeing that my application will have no 

    idea what service it will have to work with at runtime.

Is there a way to achieve this?

Thank you for any help in advance!

Class Diagrams

Class diagrams show the static structure of the systems. Classes define the properties of the objects which belong to them. These include:

Attributes - (second container) the data properties of the classes including type, default value and constraints.

Creating a Simple Class in C#

The second article in the C# Object-Oriented Programming tutorial describes how classes are created in C# and how behaviour, in the form of publicly visible and private, hidden methods can be added. This demonstrates some of the uses of encapsulation

Static Class for Beginners

In general, the members of a class can be accessed by instance of that class when they are in public, but there comes a situation to access or call members of a class without an instance and this can be achieved by declaring them as static

Dynamically Create Controls in ASP.NET by Using Visual C# .NET

This article demonstrates how to dynamically create a control for an .aspx page. The sample project does the following:

abstract away the source of the connection string using a class with a static property.

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

Let's abstract away the source of the connection string using a class with a static property.

MessageQueue Class

This sample demonstrates two way communications using message queuing between a device application and a desktop application. One application sends book order messages to a message queue and another application receives these book orders from the message queue and responds to the device queue that the orders have been processed.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

How to change the default page base class?


I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.

I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.



Can I replace the EntityObject as base-class in Entity Designer 3.5 sp1?


I'm using EF3.5sp1 for a project, and I've been working around many of its problems... as such, my entity partial classes have a lot of logic in them for change-tracking and whatnot.  Obviously, I'd like to factor this logic out into a common base class, but of course all my objects must derive from EntityObject.  Is it possible to tell them to derive from some class of my own invention (which would actually likely derive from EntityObject themselves)?

I'd rather avoid editing the EDMX file unless the changes will be safe on entity-model-update, since I'm still making changes to the database schema in this early state of my project.


Also, is there any good workaround for the fact that the change isn't tracked when you change EntityReference.EntityKey?

using the linqDataSource control programmatically (dynamically)



my scenario is this: I want to use the linqDataSource control to bind data to a gridview for it's efficient built-in paging and sorting features *but* I don't want the data to be bound until the user has input various search parameters, so I need to bind the data from a button click event. Also, the search options will be somewhat complex in that there will be several optional search parameters, via various dropdowns and textboxes, so I can't just declaratively/statically setup all the WHERE parameters on the linqDataSource (at least I'm assuming I can't, or that it may result in poor performance if I do and just assign default values like the everything wildcard '%' for the cases the user doesn't use a particular search parameter). Given that brief description, here is an example of what I'm doing, but with only one WHERE parameter for simplicity, the real code will be adding anywhere from 1 to about 12 WHERE parameters depending on how the user sets the search options in the GUI.

the linqDataSource on the aspx page:

<asp:LinqDataSource ID="ldsMain" runat="server" 
        Select="new (field1, field2, field3, etc..)" 

Search for a string in my datasource dynamically


I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
            SQuery = "[contains(title), 'asp')]";

Singleton Pattern and Abstract Class


I know what Singleton Pattern means and Abstract class means.

What I wanted to know was how would this apply to real world.

Could anyone give me any good example or simple explanation.

Say I have a simple website, why would I use any of the above if any.

Why would it simplify my architechture.

Thanks in advace. 

How to implement custom HttpContext for each request under class that implements IHTTPHandler


Hello All,

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.

Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.

After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)

Code is as follows.

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
            Dim requestedUrl As String
            Dim targetUrl As String
            Dim urlLength As Integer
            'Save settings which will be used while redirecting to appropriate page
            requestedUrl = context.Request.RawUrl
            If requestedUrl.IndexOf("?") >= 0 Then
                targetUrl = requestedUrl.Substring(0, requestedUrl.IndexOf("?"))
                targetUrl = requestedUrl
            End If
            If targetUrl = Nothing Or targetUrl.Length = 0 Then
                targetUrl = requestedUrl
            End If

Persist data in a dynamically populated ListBox in a user control


Hi All,

I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details

I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.

My Page_Load Function

void Page_Load(object sender, EventArgs e)










My Click Function

Protected Void Button1_Click(object sender, EventArgs e)


       string strValue = listBox.SelectedValue



I have placed brake point at Page_Load and on click function, I am seeing that the moment the breakpoin

Using a GenericHandler as a WebResource inside a Class Library



I hope this is the right place to ask this question.

I'm trying to make a control class library. I want to have a GenericHandler as a WebResource so I could call it from the web project that will use that control.

I need this handler will get parameters from the query string and return JSON data acourding to what it get in the QS.

I know how to create JS and images WebResources, so I tried the same on a generic handler I added to the class library project but all it does is return the source of the handler file and not the result.


Is what I'm trying to do possible? If so, what should I do?


Thank :-)
