It works when doing this :
<xctk:ValueRangeTextBox Text="AA">
<Trigger Property="xctk:ValueRangeTextBox.HasValidationError"

I am setting a Style for a ValueRangeTextBox as follows:

Property="xctk:ValueRangeTextBox.HasValidationError" Value="True">
<Setter Property="BorderBrush" Value="Red" />
<Setter Property="BorderThickness" Value="2" />

but then I get this error at design time:
'{DependencyProperty.UnsetValue}' is not a valid value for property 'HasValidationError'.

Yes, of course, I should be binding value, not text. Thanks for the sharp eye.

My first thought from reading the code is that you are binding the "Mileage" property to ValueRangeTextBox.Text where this Text property is a string. So, the "value" received from the Validate method will always be a string.
In the LostFocus callback, you check the ValueRangeTextBox.Value property, which can be a Int64.

I have a ValueRangeTextBox defined as follows:

ValueDataType="{x:Type s:Int64}">
<local:MinMileage />

The class MinMMileage is defined as:

Public Class MinMileage
Inherits ValidationRule

Public Overrides Function Validate(value As Object, cultureInfo As CultureInfo) As ValidationResult
Debug.WriteLine(TypeOf value Is String)
<other code>
End Function
End Class

I also have
Private Sub txtMileage_LostFocus(sender As Object, e As RoutedEventArgs) Handles txtMileage.LostFocus
Debug.WriteLine(TypeOf txtMileage.Value Is Int64)
End Sub

The Lost_Focus event occurs before the validation. The Debug statement gives True, as it should. However, the next statement executed is the Validate Function and that Debug statement also gives True, which means that the value passed to the validation function has been changed from an Int64 to a string.

Am I doing something wrong or is this a bug?

For the ValueRangeTextBox I have BeepOnError = True and ValueDataType="{x:Type s:Single}"

When I enter an alphanumeric into there is no beep. What are the conditions that will trigger the beep?

"s" namespace can be define like this :

SezMe Mar 8, 2016 at 1:15 AM 
Good examples but how is the namespace "s" defined? (Sorry to be a bug - I've just started using the Toolkit)

BoucherS Mar 7, 2016 at 1:39 PM 
here are examples :
<xctk:ValueRangeTextBox MinValue="10" MaxValue="20" ValueDataType="{x:Type s:Int32}"/>
<xctk:ValueRangeTextBox MinValue="0" MaxValue="10" ValueDataType="{x:Type s:Double}"/>
<xctk:ValueRangeTextBox MinValue="0" MaxValue="10" ValueDataType="{x:Type s:String}"/>

SezMe Mar 7, 2016 at 7:31 AM 
What are valid ValueDataTypes? I cannot set anything (string, Int32, etc.) in XAML or code)

I'm sorry, my problem is caused by the Value defined as "string". So during ValueRangeTextBox initialization the Exception is thrown.

fedemonte89 Apr 8, 2015 at 4:26 PM 
Is it possible to bind ValueDataType to any attribute of an object?
Now I'm trying to do something like this:
<xctk:ValueRangeTextBox ValueDataType="{Binding PrimitiveType, Mode=OneWay}" />

but an Exception is thrown. Is there any solution?

Thank you for all your work!! :)
