Currently, performing consecutively paste operation does not work like in TextBox. In TextBox the strings are concatenated but in MaskedTextInput the caret is in the beggining and only the first paste is successful. The XAML team has recently reviewed the status of this feature request and will not be addressing it in future. Consecutive Paste operation works in No-Masked scenario (Set Mask=""). Changing the paste behavior in masked scenarios would be a breaking change for some of our clients.
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
Use No-Masked TextInput (Mask=""). Pressing delete will always place the caret on position 0.
Pasting 5788250000028292 in NumericInput with Mask = # 19 will cut the last digit 2. Pasting the same number in CurrencyInput will produce an exception.
Mask="Pddd" should disallow letters. However, after select all, you can type letter in the position of the first "d" Available in LIB Version: 2016.1.125.
Placeholder is set to " " and the SelectionOnFocus is set to CaretOnBeggining. When the Mask receives the focus, the caret is under the MouseClick position, not in beggining. After load and clicking in the center of the MaskedInput , no value can be inserted. The xaml team recently reviewed the status of this issue and won't be addressing it in future. Placeholder set to string.empty or ' ' should be considered not supported. Please consider using Mask="" (no-mask) instead.
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.
RadGridView with CellEditTemplate with RadMaskedDateTimeInput. Select a GridViewRow. Press ALT + N Key (or other key with letter/digit). Argument Exception occurs in MaskedDateTimeGridViewEditor. The issue is reproducible in Q3 2015 SP (1104) version of Telerik UI for WPF. The fix will be available in Q1 2016 Release.
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.
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. Available in LIB version: 2014.3.1124
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. Available in LIB version: 2014.3.1124
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".
I think it would be great to have a IsMultilineAllowed property for this control, as AcceptsReturn property is only designed to ignore the return key entered by the user. Here is my post in the forum: http://www.telerik.com/forums/paste-multi-line-text-when-acceptsreturn-set-to-false ======== Reason for Decline: The desired request is custom logic that could be implemented by inheriting the RadMaskedInput control and overriding HandlePaste.
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.
