Building a Custom Data Grid: Performing Ad Hoc Web Reporting with a VBScript 5.0 Class Object

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

A flexible, customizable grid for displaying data is a useful tool for ASP developers. It allows Web visitors to customize their view of your data. This article takes the data grid presented in "Ad Hoc Web Reporting with ADO 2.0" by John Papa and Charles Caison (MIND, December 1998) and adds handy features such as a finds feature that supports multiple finds and a mode for adding and editing records. This version also improves response time by allowing asynchronous record download and it componentizes the code so it can be used as a standalone VBScript class object that can be reused in other pages.

In this article, the author will develop one such report renderer that outputs HTML reports, but the skills you'll learn can easily be used to create a renderer for Microsoft Word documents or any other format of your choosing.

ADO.NET: Building a Custom Data Provider for Use with the .NET Data Access Framework


The System.Data.dll assembly in the .NET Framework contains namespaces whose base classes can be used to create custom data providers. These namespaces also define a number of data access interfaces and base classes that let developers create data providers that will interoperate with other custom providers. Using the ADO.NET classes Connection, Command, DataReader, and DataAdapter, writing a provider is easier than writing one for OLE DB. This article explains these classes and their implementation, and how they can be used to write a variety of different kinds of data providers.

Calling a method with a class object as parameter data type.

   [WebMethod]    public string GetInfo(Customer inCust)    {        // Code in here    } I have a web service that resides on a remote server. I want to call a public method of theweb service named  "GetInfo". The method is shown above. The web service method expects a class object oftype "Customer". What I did to create a Customer object was to define in my asp.net project my own class named "Customer" which is exactlythe same as the class that belongs to the web service project on the remote server. I then created an instance of Customerand tried to call the web service passing in an object of type customer : my.Service ws = new my.Service(); // Get web service connectionCustomer aCustomer = new Customer();aCustomer.Initialize();ws.GetInfo(aCustomer) // call web service passing in a Customer object The problem is that the compiler gives me the following error: Value of type '_Default.Customer' cannot be converted to 'ws.Class1'. Here Default is refering to my Default.aspx.cs code. Why is this? Do I need to Cast my "aCustomer" class object to a type ofws.Customer ? How do I do that?

Unable to Create Object Variable for Linq Data Class


For some unknown reason I suddenly am unable to create an object variable for a Linq Data Class. If I create a new project and try the process again with the same database everything works as advertized.

The code I am using is Dim db As New RoggDataContext  which gives me an error on the object variable "db": Overload resolution failed because no accessibility 'NEW'  accepts this number of arguments.

I have looked inside every file in the Web Project like the web config to check the connection string, gobal, and designer.vb looking for any errors whit no JOY.  I also tried to create a new form and code behind with a button and received the same error.

This is mind blowing because as I already stated, I can create a new Web Site and the problem goes away.

Any help is appreciated!



Problem with adding custom propety to a data class using Linq.



I tried to add a custom property to the data model:

public partial class Department
        public string ExtensionIdName
                return Extension.ExtensionName;

It seems that it works, but when I bind the data to a ListView it shows all the properties except the property I added manualy (ExtensionIdName).

Am I missing something or is there something wrong?

Generic list of custom class returns data in WCF service layer, but loses them in Presentation Layer


I'm reading this excellent article by John Papa in MSDN Data Points - http://msdn.microsoft.com/en-us/magazine/cc700340.aspx

This single article alone sheds great deal of light on EF, WCF, WPF, MVP architecture, Layered Architecture with these technologies and so much more.

I'm trying to experiment with the code that comes with the article as is.

When executing the application, the service layer returns a Generic List with three Customer objects to the presentation layer. However, in presentation layer, the Generic list arrives with zero objects in the list. In the context of this application, I provide 'd' as a search criteria and hit the search button; while stepping through, I can see it returns 3 rows from the database.

With my limited experience in WCF, I am unable to figure out why it is so. This article was written  for 3.5 SP1 Beta 1. Could something changed in the general release that is causing this?

Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

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

Posting data to ASMX and return Object for jQuery


I am using fluent NHibernate with WebForms and I am trying to build a page where I allow a user to post a status update on their profile page and I a using a .asmx WebService to post the data to the database and then returnig a StatusUpdate instance to the page to be used by jQuery. I have a couple problems.

1) First off when I return a string from the WebService(i was testing) the textbox where the user enters their status doesnt empty the contents. And since the page doesnt refresh even if I manally clear out the textbox and put in something else, it still posts the previous status to the database again. How do I fix this?

2) Secondly, when I return the StatusUpdate Object from the Webservice I cant the results to display anything. Like I sad, Im using jQuery to make an AJX call to the WebService.

Here is my code:

User Profile Page:

Status: <asp:Label ID="status" runat="server"></asp:Label><span style="font-size:.7em;"><asp:Label ID="statustime" runat="server"></asp:Label></span><br />
<textarea id="statusBox" rows="3" cols="40"></textarea><br />
<input type="button" value="Update Status" onclick="SetStatus(); return false;
