When UpdateValueEvent is set on PropertyChanged and the mask uses upper/lower token(s) the letters/characters are updated to uppercase after filling the mask. The control should update its text on every key stroke.

Update:
We are closing this issue because this is expected behavior in MaskedInput.
Value property is updated if all required symbols (required from the Mask) are populated. If you need the Value to be updated on every symbol entered you can set the property AllowInvalidValues = True.

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.

MaskedInput focus behaves different when it is set in code behind. When the textbox is on focus and new character is entered the text remains the same and the new character is added at the beginning of the textbox.

Scheduled for:
The fix for this issue will be available with LIB (version 2019.1.128) scheduled for publishing on Monday, 28th January 2019.

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

It must place the caret on the first position. 

Users sometimes need to invoke Undo / Redo. Public command properties would be a possible way to go.

GridView with GridViewDataColumn.CellEditTemplate.

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

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.

Numeric or Currency Input with Value = Null.

Clicking minus key (OemMinus or NumpadSubtract) places minus but Shift + OemPlus (or Numpad Add) does NOT remove the minus sign.

Will be available in Q1 2016 Release.

The 'hh:mm' Mask is not applied correctly in the DateTimeInput when the control is focused.

For example if the date is 2014-05-23, 22:30, and the Mask property of the control is set to 'hh:mm' the displayed text should be 10:30. Currently, this text is displayed only if the input is not focused, otherwise the text changes to 22:30

Currently the MaskedInput controls cannot parse strings containing such full-width symbols.

Actually the .net framework also cannot directly parse such symbols.

Currently users are not allowed to completely remove or customize the Undo/Redo actions in the RadMaskedInput controls. Consider adding extensibility points such as commands or events.

Mask="Pddd" should disallow letters.

However, after select all, you can type letter in the position of the first "d"

It would be really useful to be able to specify a maximum number of significant figures for Telerik RadMaskedNumericInput as this was requested by a client.

Mask is like "##--##". Current Value is "1234" and you see "12--34" Caret is between 2 and "-".

Pressing 3 wiill not move the caret after the digit 3.

InputBehavior is set to "Replace"

In NoMask scenario the Placeholder should not be a valid property. The issue: if the Placeholder is an underscore (default value) and the user's input underscore this character is not displayed on lost focus.


Workarounds: 

1. Set empty string for Placeholder (Placeholder="")

2. Set TextMode property to MaskedText (TextMode="MaskedText")

If a user has selected all text in a numeric masked input control with a decimal (eg. 12.34), if they start typing a new value with a period (eg user types .89), the integer potion of the decimal does not change (so the input control now displays 12.89 instead of 0.89). Please provide a way to clear out what's to the left of the decimal when users type the period, as this is much more inline with the expected behavior of pretty much any other input control. 

The user has selected all the text and started typing. There's no excuse for not clearing out all the text in the input control in this scenario. Our clients are rightfully frustrated with this behavior.

The workaround is to create a custom class which derives from RadMaskedTextInput and override the OnSelectionOnFocus() method.

 protected override int OnSelectionOnFocus(SelectionOnFocus selectionOnFocus)
        {
            if (MaskedInputExtensions.GetCaretToEndOfTextOnFocus(this))
            {
                return this.Text != null ? this.Text.Length : 0;
            }
            if (selectionOnFocus == SelectionOnFocus.Default)
            {
                return 0;
            }
            return base.OnSelectionOnFocus(selectionOnFocus);
        } 
Then you can set the following properties to the mask:
 -  TextMode="PlainText"
 -  Placeholder=" "
 -  maskedInput:MaskedInputExtensions.CaretToEndOfTextOnFocus="True"

The issue is reproducible with NoMask and UpdateValueEvent=LostFocus. The Clear button clears the whole content while deleting with the Backspace and Delete keys leaves the separator symbols. When the focus is moved outside of the masked input, the symbols are removed.
