Problems with multiple validation rules

Posted By: Posted Date: September 24, 2010 Points: 0 Category :WPF

Hi!

I've added some custom validation rules programatically like this:

BindingOperations.GetBinding(txtTitulo, TextBox.TextProperty).ValidationRules.Clear();

BindingOperations.GetBinding(txtTitulo, TextBox.TextProperty).ValidationRules.Add(new ReglaDatoRequerido(Idioma.RecursoIdiomaLocal(this, "msjErrorDatoRequerido")));

BindingOperations.GetBinding(txtTitulo, TextBox.TextProperty).ValidationRules.Add(new ReglaRangoDatos(Idioma.RecursoIdiomaLocal(this, "msjErrorDatoRequerido"), 1, 5, false));

these are the rules:

public abstract class ReglaValidacionBase : ValidationRule

{

/// <summary>

/// Mensaje de error.

/// </summary>

public string MensajeError { get; set; }

}

public class ReglaDatoRequerido : ReglaValidacionBase

{

public ReglaDatoRequerido(st

Web Services: Extend the ASP.NET WebMethod Framework with Business Rules Validation

In an earlier article the authors showed how to build a custom WebMethods extension that provides XML Schema validation, a function that is lacking in ASP.NET. In the process they established a foundation for enforcing business rules during the deserialization of XML data. The technique, which is described in this article, uses declarative XPath assertions to test business rule compliance.In building this business rules validation engine, the authors integrate the validation descriptions into the WSDL file that is automatically generated by the WebMethod infrastructure. Finally, they demonstrate how to extend wsdl.exe, the tool that generates WebMethod proxy/server code from WSDL files, to make use of their extensions.

Multiple forms on the same page MVC2: how to handle (including validation from model)

Hi,

It should be simple; although I'm having a hard time to figure out the best way to do it. I've MVC2 pages with multiple forms on the same page having different functionalities.

What's the best way to handle this; including the MVC2 way of validation from the model?

Thanks.

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

Help on Binding validation rules

Defining Validation rules with Data annotations - ???

I am having following problem:

Defined RegisterModel class - with some validation rules for creating new users, and this works fine.

Then I get this class, strip few properties and wanted to reuse it as UserInfo_Form_Model, for editing user properites.

No changes, just deleted few items, renamed and reused in strongly typed View for editing.

And result of validation is: -

[DisplayName("Name")] works fine, showing correct

[StringLength(20, ErrorMessage = "xxxx...")] - not working, no message showed when suppose to be one

[Required(ErrorMessage = "xxxx.")] - not working, not showing messages when delete required values?

but (ModelState.IsValid) is false when I checked it in controller (it had to be because required value is missing)?

Is it this only partially correct and how this can be?

Well this is a bit frustrating because it cant be simpler than this and I cant make this simple code reuse. :|

Quite a few gotchas I already found or I am coding completely wrong.

Problems with multiple calls from the same client

Hi all!

I have a service with the following binding configuration (identical on server and client), running under IIS (Win 7 x64):

<netTcpBinding>
 <binding name="Printec.TMS.DCS.WindowsTcpBinding" maxReceivedMessageSize="6553600" 
  maxConnections="2000" listenBacklog="2000" closeTimeout="00:10:00" 
  sendTimeout="00:10:00" receiveTimeout="00:10:00" openTimeout="00:10:00">
 <readerQuotas maxDepth="200" maxStringContentLength="6553600" maxArrayLength="6553600" />
 <reliableSession enabled="false" />
 <security mode="None" />
 </binding>

Here is the service behaviour:

I'm having a lot of problems using XmlDsigEnvelopedSignatureTransform when signing an XML document multiple times. For example, I have a simple document and I add a signature to it, then, when I check the document, the signature is valid and everything
is fine. But when I add a second signature to the previously signed XML then the problems begin: the second signature is valid, the first one not! This seems like if the XmlDsigEnvelopedSignatureTransform is not removing the already existing Signature
nodes (as from W3C specifications) from the document before signing and when verifying, so the second signature broke the first one. This behavior is also specified in the MSDN documentation:
The XmlDsigEnvelopedSignatureTransform class removes the <Signature> element from an XML document before the digest
is computed. With this transform, you can sign and verify all elements of an XML document except the XML digital signature elements.
To confirm this, I've tested the example found in the official documentation and the results are like I imagined, the Signature element is not removed:

firing Validation rules under One way binding Mode
Can Validation Rules fire When binding Mode is set to OneWay.?
If No : Is is Because the validation rules fire only when the source property changes and hence under oneway binding the source never changes and so the rules never fire.
Is there a workaround to Fire the validation rules Except invoking the explicitly.( Because i have triggered the save button to be enabled only when ther's no validation errors, So makin the user click and explicitly firing rules is not what i want.)

problems with trace.writeline not writing output messages on multiple instance/thread service
Hi,
I've come across something strange and can't quite figure out what could be going wrong. I have a windows service which processes queue items in a threadpool (default 5 threads).
So, during testing, i "debug, start new instance" and spin up about 4-5 instances of the service, and on average there is about 25 threads going at same time.
My trace code:

Trace.WriteLineIf(traceOutput.TraceVerbose, string.Format("processing Item for {0}", item.id));
this seems to work for a while and writes the trace code to the output window, but after a while, the trace output just stops being output to the window.. has anyone else experienced this before or could know what might be going wrong?
thanks,
Paul

Cannot get recommendations after querying an association rules model for multiple customers
To carry out this data mining task, I am using the Data Mining(DM) add-in of Excel 2007,
where one has to make use of SQL Analysis Server in order to utilize the add-in.
Basically, I have a three-column dataset: CustomerID,Product,Transaction. These are the steps I am following:
1. Build an Association Rules(AR) Model.
2. Query the AR Model with new data and obtain a recommended product.
Right now, if I supply an input of Products "A","B","C" for "Customer1" I get the recommendation e.g. product "D".
This is the DMX query I am using:
##############################################################################################################
SELECT
PredictAssociation([Associate ProductNo].[ProductNo_Table],INCLUDE_STATISTICS,5) AS [Output 1]
FROM
[Associate ItemNo]
NATURAL PREDICTION JOIN SHAPE
{@InputRowset } APPEND ( { @InputRowset1 } RELATE [SessionNo]
TO [SessionNo] ) AS [ProductNo_Table] AS T
InputRowset = Microsoft.SqlServer.DataMining.Office.Excel.ExcelDataReader
InputRowset1 = Microsoft.SqlServer.Data
Multiple database support with Entity Framework
One of the features introduced in Entity Framework is being database independent. Which mean each database provider can support Entity Framework by implementing its provider.

This feature allows you build applications independent from the underplaying database provider. In this post I'm going to show how to build an application that support multiple databases using same conceptual model made by Entity Framework.
