Issue with validation using IDataErrorInfo with int range

Hi, I have a textbox which takes only numbers as input. Textbox has binding with int type property. <TextBox Name="TXT_From" Text="{Binding Path=Range, UpdateSourceTrigger=LostFocus,<br/> ValidatesOnDataErrors=True, Mode=TwoWay}" /> public int Range { get { return (int)GetValue(RangeFromProperty); } set { SetValue(RangeFromProperty, value); } } public static readonly DependencyProperty RangeFromProperty = DependencyProperty.Register("Range", typeof(int), typeof(MyClass)); In IDataErrorInfo I am doing some auto correction of values. public string this[string property] { get { string msg = null; switch (property) { case "Range": if (Range < 0) Range = 1; if (Range > Max) Range = TempMax; break; default: throw new ArgumentException("Unrecognized property: " + property); } return msg; } } Now the issue is when I enter value greater than 2,147,483,647 which is max value for int the IDataErrorInfo member public string this[string property] is not getting called,also it displays red bordered textbox. I want to avoid this validation and dont want restriction on value input. How to achieve this?

Range Validation Rule

In this post I will show you one of the rule which is quite often used in applications is the Range validation, To check the range of the input user control so that user can't enter less or more then the minimum and maximum value respectively. In my previous post I have show you how to use the validation rules you can read it if you don't have any idea about the validation rules.This post is the continuity of the previous post.
Let us start with the range validation rule example. The example code for this example is the same as I have used for the previous post I have added new validation rule with the name of the RangeValidation in the ValidationRules folder, where all the validation rules are placed.In the List 1 you can see the complete class for the RangeValidation rule. Here you can see that I have three properties one for the MaximumLength and MinimumLength for checking the maximum values entered in the user input control and to check the minimum value entered by the user in the input control respectively.

Regex validation of a range of digits

Hi,

I need to check if a variable is inside of a range.

E.g. I'll like to check if variable "input" of type Int32 with the value 5 is in the range from 0 to 15.

I've tried with

if (Regex.IsMatch(input.ToString(), "([0-9]|1[0-5])"))

{

Console.WriteLine("In the Range");

}

It doesn't work :-(

Can somebody help,

ThanX :-)

VS 2010 HTML validation "in CSS" option - where the hell is it?

In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.

1. am I blind?

2. they decided it is too convenient to use and removed it?

3. they will "introduce" it in SP1?

What is going on? That one thing made me move back to VS 2008 web developer.

set messageTemplateResourceName from resource file in Validation appication block.

Hi,

I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.

Here is my code:

<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250"
              upperBoundType="Inclusive" negated="false" messageTemplate=""
              messageTemplateResourceName="PerilTypeAndDetailsSection.VMEnterWhere"
              messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"
              tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris

Localize framework message from xml validation error

I need to validate an XML through XSD. I am using XMLReader (with XmlReaderSettings and

Validation_EventHandler to do it). Depend on users preference, I would like to change the output message generated by Validation_EventHandler in french or english.

Any idea on how to perform this?

Thanks

System.DateTime.AddDays: Value to add was out of range.

I'm getting the following error:

[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
   System.DateTime.Add(Double value, Int32 scale) +7657639
   System.DateTime.AddDays(Double value) +19
   ...

The line from which this error originates has the following code:

expires = Now.AddDays(30)

It occurs irregularly and irreproducably. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative.

It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Any ideas? Culture settings perhaps?
