In Q3 2013, Focus() or KeyBoard.Focus() cannot focus the MaskedInputControls so that their Caret is blinking and ready to receive input.
Also, FocusManager.FocusedElement used to do the same  in previous releases but in Q3 it doesn't.

Pasting text in TextInput with No-Mans and UpdateValueEvent=LostFocus is not successful.

This operation clears the whole Value.

 <telerik:RadMaskedTextInput Mask="" UpdateValueEvent="LostFocus"/>

Available in LIB version: 2014.3.1305

If Mask = "\A\B\C\D####" (A, B, C, D are escaped) and NumericInput is used. Select All , then typing 1234 produces something like 4312.

Available in LIB version: 2014.3.1222

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.

If you try to paste text in the RadMaskedTextInput control using the default ContextMenu, after the Clear button is pressed (or after delete with backspace), the Paste command is not working as expected.

Part of the Value or the whole value is selected in no-masked NumericInput.

Pasting a copied text is not successful. For example 4 is the value and 4 is selected. Pasting "123" produces "1" but it should produce "123".

MaskedNumericInput with Mask = #6.3. When there is no digit grouping (you can turn it off from  the region / format settings in windows, no digit grouping means no symbol for grouping) the control produces Exception on load.

GridView with GridViewDataColumn.CellEditTemplate.

In it MaskedTextInput is initially Collapsed. Double clicking the Cell will produce a Null refecence exception.

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.

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.

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

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".

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.

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.

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.

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"). 

Pressing ClearButton of the RadMaskedDateTimeInput will place the caret on the last position.

It must place the caret on the first position. 

If you set the OS culture to Dutch (Belgium) and set the Decimal symbol to "." and the Digit grouping symbol to "," you are not allowed to enter 5 digits into the RadMaskedNumericInput control.
