Looking for advice on how to code a data-driven app

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :ASP.Net

I am looking for some guidance on how to proceed with a database-driven ASP.NET 4.0 application. The requirements are that the end user must be able to do the following:

- Resize columns
- Rearrange columns
- Edit the data (if they have the correct permissions)
- Sort the columns
- Filter the data (e.g., show only certain columns or rows)

In addition to the above, whatever the end user does in terms of resizing, rearranging, etc. must be stored or "remembered" somehow by the application so that the next time they login, their settings will be customized to their liking so that they don't have to keep reconfiguring things every time they use the application.

Do you know of anything, besides Silverlight, that can be used in conjunction with ASP.NET to accomplish the above goals?

Silverlight is out of the question for reasons which I won't get into. I have looked into using the Yahoo! User Interface (YUI), which will work to some degree. However, I'm not sure how the user's preferences can be stored for future use, and that is a key requirement. I wonder if column widths, arrangements, and filter settings can be stored using the Profile feature of the ASP.NET Membership Provider?

Trustworthy Code: Exchange Data More Securely with XML Signatures and Encryption


You can sign any kind of data using XML Signature, including part of an XML document, other XML documents, or other data of any format. However, in practice, XML signatures are most frequently used to sign other data represented in XML. In this article, the authors discuss the new standard and how you can benefit from it in your apps.

Data: More Load, Less Code with the Data Enhancements of ASP.NET 2.0


A data source control is a server control that wraps some basic functions of a data source - be it a SQL Server database, an XML document, an Excel worksheet, or a sitemap description. Through the services of a similar component, data-bound controls can fetch data as well as insert new records or update and delete existing ones. Data source controls enable a consistent model across a variety of data sources and dramatically reduce the amount of code needed to implement a two-way data-binding scenario. This article provides an introduction to data source controls and other related data binding features.

SQLXML 3.0: Build Data-Driven Web Services with Updated XML Support for SQL Server 2000


XML is becoming the ubiquitous data format on the Web, and XML support in SQL Server is evolving to meet the additional demand. Using XML, SOAP, HTTP, and SQL Server, you can now build powerful Web Services easily. To show just how simple it is with SQLXML 3.0, this article walks the reader through the process step by step, from setting up a virtual directory enabling data access via HTTP to executing queries and building Web Services. Finally, the author illustrates the creation of two Web Services clients-one with C# that works with the Microsoft .NET Framework and one with the SOAP Toolkit 2.0 for anyone still using earlier development tools.

Using Server-Side XSL for Early Rendering: Generating Frequently Accessed Data-Driven Web Pages in A


Dynamic data-driven pages have become the basis of many cutting-edge Web sites. Early render systems can provide better performance and maintainability for data-driven Web sites by generating frequently accessed pages that contain less-volatile information ahead of time. We'll show you an example of a server-side solution that uses Extensible Stylesheet Language (XSL) to merge data and layout information into HTML that is compatible with just about any modern Web browser. Using these techniques to render Web pages early can reduce the load on your database back end and increase performance for your users.

Trying to run a stored procedure from vb code with oracle data provider.



Here is my SP:

create or replace
 Open p_getuserssignon_recordset1 for
 SELECT Distinct(Userid), UserPassword, SecurityLevel, ActiveStatus
WHERE substr(UserId,1,2) <> vUid
Order By UserId;

I would like to run this SP from code and fill a gridview with the result. 

I am not sure how to go about this, as I have found several different examples, other than the one I  think I need.

I am using the oracle data provider and I have an input parameter (vUid, which will equal "zz").

First question. When filling a gridview with a result set from a stored procedure should the recordset OUT be defined as a REFCURSOR (like i did above)? 


Do you have example code as to how to execute the SP and fill a gridview?  I keep trying different variations of code i've found on the internet without any success other than getting more confused.

(I am using VS 2005, VB).

Thank you.



DataGrid ValidationRule or IDataErrorInfo validation code called multiple times for each data change

Following my enquiry regarding a problem in Datagrid validation, for which managing exceptions is apparently a problem, I tested the two other methods: using validation rules, or implementing the IDataErrorInfo interface. I ran into other problems there, more insidious this time. This has been done on Windows7 (32-bit), .NET 4.0.30319. 1) IDataErrorInfo When this interface is implemented, the this[string columnName] property is called four times for each modification: two times before the cell enters edit mode (with the old value in the corresponding property) two times when the new value has to be validated (with the new value) It strikes me as not really efficient, is there something wrong with my code? Here's the C# part: using System; using System.Windows; using System.Collections.ObjectModel; using System.ComponentModel; namespace DataGridTest2 { public partial class MainWindow : Window { ObservableCollection<User> users; public MainWindow() { InitializeComponent(); users = new ObservableCollection<User>() { new User { Name = "Teddy", Age = "2" }, new User { Name = "Avi", Age = "19" } }; datagrid.ItemsSource = users; datagrid.Focus(); } } public class User : INotifyPropertyChanged, IDataErrorInfo { string name; public string Name

Solved: LDAP authentication: error code 49 - 80090308, comment: AcceptSecurityContext error, data 52

Hi, I have a problem conneting to another domain (far.away.domain). We have a two-way trust to this domain. Also I can access the DS using ADSI edit and our Administrator account (ourdomain.com). I tried several types of credentials (userid = "CN=Administrator,CN=Users,DC=ourdomain,DC=com", "Administrator @ ourdomain.com" (without blanks)...). Connecting to ourdomain.com is no problem, but to far.away.domain I can't connect, I always get the error 525 (user not found). What could be the problem? Have I to use an entry from the ForeignSecurityPrincipals CN of the far.away.domain? I also tried to connect using Softerra LDAPBrowser and a command line ldapsearch without succes and with not a better error message. But why is it not possible to use a trusted account, or is this a active directory feature and does not work with pure LDAP bindings? Best regards, Nils.

Adding source redirect code to end of a URL which used a dynamic data value

I'm trying to add some source redirect code to the end of a URL in a Data Form Web Part on a simple SharePoint aspx page. This is the basic url: /itservices/helpdesk/Lists/Service%20Requests/DispForm.aspx?ID={@ID} However I want to add a source redirect to the end of the URL so that it returns to a particular page rather than the list's default page. I have tried all of the following: /itservices/helpdesk/Lists/Service%20Requests/DispForm.aspx?ID={@ID}&source=/itservices/Pages/MyOverview.aspx That causes an error in the web part stating "This Web Part does not have a valid XSLT stylesheet: Error; A semi colon character was expected". I tried replacing the ampersand with the URL encoded character: /itservices/helpdesk/Lists/Service%20Requests/DispForm.aspx?ID={@ID}%26source=/itservices/Pages/MyOverview.aspx But when opening from this URL the form contains no data. What am I missing or can this not be done? Thanks.
