Old Name was. "Implement a feature to change the Value property based on the Text property ". However, Value is the primary property for this control and that is why we want clients to use Value property, not two-way binding of the Text property that changes the Value internally. That is why we changed the name of the feature request.

Its meaningful and clients will benefit from it. Basically clients want the literals to be included in in the VALUE. And this is meaningful only in TextInput. So new property in RadMaskedTextInput (for ex. IncludeLiteralsInValue) seems fine - Estimate 10. 

Example Scenario: 

Mask="##--##--##", 

User types 123456, Value property becomes "12--34--56" which will have the same value as the Text property.

Example Scenario:

IP Address SDK demo. Look at its code - there is converter in file and convert methods in ViewModel.cs. Both Value and Text are bound. If Value includes the dots, only 1 converter and 1 2way bingding would do the job with less code.

Add built in masks for Email, IP, Phone, etc. Add design time support for this.

When using German Culture, NoMask and FormatString = "n0" , an incorrect input is produced.

For example pressing 4 times "6" will produce a Value of 7.

This is a parsing issue (6666 becomes 6.666 where "." is a grouping symbol in German Culture).

Then 6.666 is parsed with rounding to 7.

Select text in the RadMaskedTextInput then Ctrl + X cuts the text but Ctrl + V does not paste it.

Steps to reproduce:
1) Type 12345. Select 345.
2) Ctr + X.
3) Ctrl + V won't do anything. (345 is not pasted) the result is - "_______________"). 
Expected result is: "345". This  should replace the whole text with the copied one. SelectionStart is not changed after paste.

Notes:  This bug is only for the scenario Cut + Paste in the MaskedTextInput with Mask. 
Pasting in No-Masked MaskedTextInput (Mask="") should work much like pasting in normal TextBox (in the same scenario the result should be "12345"). 

When the user inputs digits in the RadMaskedNumericInput and then inputs some Spaces, the Value property is not changed although the UpdateValueEvent="PropertyChanged". It is only changed when the focus is lost.

Hitting dot or comma on the keyboard doesn't move the cursor after the decimal separator in the MaskedNumeric/CurrencyInput controls in Mac

The minus key on a Mac keyboard, doesn't toggle the sign of the values in the MaskedNumeric/CurrencyInput controls. However, if an external usb keyboard is attached to the machine, it can be used to toggle the sign as expected.

Japanese input symbols are not correctly displayed. Empty symbols are shown on left of the japanese symbols.
Exception occurs when entering  n japanese symbols with mask = an. For example when Mask = "a4", 4 symbols entered in MaskedTextInput. This might lead to a crash.

Numeric input with  Mask="#7" or CurrencyInput with       Mask="c7" .

 UpdateValueEvent="LostFocus"

Value =3000

If you remove the digit "3" with backspace / delete and then type digit 4,  You will receive value"4" and text "0004".

The expected result is Text="4000" and value =4000.

Workaround:  Use Mask="" (no-mask).
=============
Fixed in R3 2016.

In Insert Mode digits are not inserted properly. For example, with Value 123456 - when caret is between 3 and 4 pressing digit overwrites the digit 4 but is shouldn't

User should be able to input 123.1.1.10 , currently only 123.1__.1__.10_ is achievable.

IpAddress demo will be added in our SDK with Q2 2014.

The AcceptReturn=True doesn't work in a MaskedTextInput with Mask="l20" (l is the small letter of L ).
Controls behaves expected when the Mask is "a20".

Change the InputBehavior when deleting digits after the decimal symbol: For example if the cursor position is marked with '|': Enter: 1234,56|78  (press 'del') Result: 1234,560|8 - change this behavior so that the result can be 1234,56|8.

=====

We can split the request into 2 desired results. Input: 1234.56|78. Pressing Delete

1) Produces Value 1234.5680 but NOT 1234.5608

Solution: Can be achieved with using No-Mask, FormatString and overriding MaskedNumeric/Currency Input and the protected method ReplaceChar. This is demonstrated in the attached sample.

2) (1) is True + Last zero is removed => 1234.568 but NOT 1234.5680

Solution: 2 is tightly coupled with changing the FormatString or Mask dynamically. There is no way to see number 123.456 if the Mask is "x.4" or the Mask is "" + format string is "n4". To see 3 digits only after the decimal point you need to change the Mask to "x.3" or the FormatString (in no-masked scenario) to "n3". This cannot be built-in feature because it changes a public property set by the client. So, this is custom behavior, it is also demonstrated in the SDK demo DynamicFormatString (it is pushed in GitHub with Q2 2014 Release)

In the Currency and NumericInput controls, clear the sign of the value on SelectAll in order to allow the user to enter a negative value again. At the moment when everything in the controls is selected, the minus key only toggles the sign of the value. Instead you should be able to select a negative value and replace it with another negative value by entering the minus key and the new value.

MinusKeyCustomizations demo is added in our SDK: https://github.com/telerik/xaml-sdk/tree/master/MaskedInput/MinusKeyCustomizations 

When the layout of the keyboard is AZERTY the minus key is not working as expected.

Available in LIB version 2017.3.1113, it will be also available in the R1 2018 Release.

You have the following scenario:

The UpdateValueEvent property is set to "LostFocus". You have bound the Value property of the control to a property from your ViewModel. 


When this property is changed programmatically from negative to positive several times, the Value property of the control isn't updated correctly.

It stays negative when it must stay positive.


Workaround (if applicable):
You can change the UpdateValueEvent property to "PropertyChanged" 

Other Possible workaround (if the bound property is named "Sum")

private void radMaskedNumericInputSum_ValueChanging_1(object sender, Telerik.Windows.Controls.MaskedInput.RadMaskedInputValueChangingEventArgs e)
{
    if (this.Sum != (double)e.NewValue)
    {              
        e.Handled = true;
    }
}

Carets Background is incosistant with the Caret's Background in System.Windows.Control.TextBox.
For example, when the Background of the control is Black, the caret shoul be white.

RadMaskedTextInput with no-mask => Mask="".

Selecting part of the value then paste works incorrectly. The selected text is not replaced and it is preserved, the copied text is inserted.

It is expected that the selected text is entirely replaced with the copied text.

MaskedInputExtensions.AllowNull is set to False. 

Select All then Delete makes the Value 0 and the Text is like "______0.00" (contains 0.00) which is expected (this is in Numeric and CurrencyInput). 

Second time SelectAll and then delete makes the Value 0 but the text becomes "________" which is not expected.
