Dear Telerik Team,

We are facing an issue in MaskedCurrencyInput when using Chinese keyboard. MaskedCurrencyInput control is showing numbers along with other characters that are not numeric. 
In case of typing alphabets, MaskedCurrencyInput is showing suggestion box of chinese characters and also showing alphabetic characters on input area.

This is working fine in English keyboards but in chinese keyboard Chinese Suggestion box and chinese characters are appearing which should not. 

Steps to Reproduce:
1- Use MaskedCurrencyInput of Telerik in XAML WPF.
2- Type alphabets e.g. abcd in MaskedCurrencyInput field box. Chinese Suggestion would appear.

Chinese Suggestion box and chinese characters should not appear. Kindly let me know if it would be resolved or any work around to stop this chinese suggestion box to be opened.

Setting these properties you can still select the control and change the text inside.

Release LIB 2019.1.422 (04/22/2019)

This reproduces only in a no-mask scenario (Mask="").

For example, if you enter the codes for º and ª, they appears as 'o' and 'a'. In other words, the bigger version of the symbol.

Here you can find an alt codes reference list:

For example the following culture:

 this.currency.Culture = new System.Globalization.CultureInfo("prs-AF"); has     


    CurrencyDecimalDigits: 2
===>  CurrencyDecimalSeparator: "."
===>  CurrencyGroupSeparator: ","
    CurrencyGroupSizes: {int[1]}
    CurrencyNegativePattern: 3
    CurrencyPositivePattern: 0
    CurrencySymbol: "؋"
    DigitSubstitution: NativeNational
    IsReadOnly: false
    NaNSymbol: "ناعدد"
    NativeDigits: {string[10]}
    NegativeInfinitySymbol: "-∞"
    NegativeSign: "-"
    NumberDecimalDigits: 2
===>  NumberDecimalSeparator: ","
===>  NumberGroupSeparator: "."
    NumberGroupSizes: {int[1]}
    NumberNegativePattern: 3
    PerMilleSymbol: "‰"
    PercentDecimalDigits: 2
    PercentDecimalSeparator: ","
    PercentGroupSeparator: "."
    PercentGroupSizes: {int[1]}
    PercentNegativePattern: 1
    PercentPositivePattern: 1
    PercentSymbol: "%"
    PositiveInfinitySymbol: "∞"
    PositiveSign: "+"

Typing 12345 in the control produces Value 123 which is wrong. Parsing becomes wrong after the group separator kicks in.

The current workaround is to create a custom control and override the OnTextInput method:

    public class CustomInput : RadMaskedTextInput
        protected override void OnTextInput(TextCompositionEventArgs e)
            e.Handled = true;

RadMaskedInput with NO-MASK (Mask="") and percentage P0 formatstring has some issues with typing digits.

After clearing the value and typing digit, caret moves after the percentage sign and editing is not possible.

For example: 

RadMaskedCurrencyInput with Culture="da-DK" and VALUE 12345.67 and Mask=#9.2. In this culture the currency symbol is "kr."

In WIndows 8, the NumberFormat.CurrencyPositivePattern is 2 (meaning '$ n').

In Windows 10, this pattern is 3 (n $). 

So in WIn8, WIn7 or WIn10 but if you change the pattern programmatically to 2. Th result is:

Actual: "kr.___.___._kr,12" this is what we see on load and on focus in control. Editing does not change the value.

Desired: 'kr. ___._12.345,67' in pattern 2

Control also produces ugly results with pattern 0 and 1. Control seems to work ok with pattern 3:

Actual and Desired: '___._12.345,67 kr.'

* this could be achieved on Win 8 with change setting or out of the box in Win10.


Workaround (if applicable and desired formatting in the specific scenario)

Set in code behind:


CultureInfo info = new CultureInfo("da-DK");
 info.NumberFormat.CurrencyPositivePattern = 3;
 this.maskInput.Culture = info;

 MaskedTextInput with Mask="(###)-###-####" and EmptyContent="Type digits" , type a single digit, for example 6 in the control.

Value becomes 6 and Text becomes '(6__)-___-____'.

 Mask is changed runtime to empty string (runtime) and the focus is out of the MaskedInput the control.

Value continues to be 6 but Text becomes '6' according to the new MASK.

 EmptyContent string is shown, although Text is 6.

Expected: Text is shown in the control '6'. 

Same issue in NumericInput and CurrencyInput.

The following workaround could be considered.

    public class CustomTextInput : RadMaskedTextInput
        protected override void OnPropertyChanged(DependencyPropertyChangedEventArgs e)
            if (e.Property.Name == "Mask")
                if (e.NewValue.ToString() == string.Empty)

This leads to a wrong value displayed in the masked input. The mask is always coerced to "hh:mm:ss.ff". An additional, 'f' is added to the mask. Probably, this will happen also if you have a single letter on another position in the mask.

To work this around you can create a custom masked input control and override its CoerceTextOverride() method. There you can implement some logic that replaces the wrong milliseconds text. Here is an example in code:

public class CustomMaskedDateTimeInput : RadMaskedDateTimeInput
	protected override string CoerceTextOverride(ref int selectionStart)
		var text = base.CoerceTextOverride(ref selectionStart);
		if (this.Value.HasValue && 
			this.Mask != null && 
			int millisecondsAllowedLength = GetAllowedMillisecondsLength(this.Mask); // example: .ff means that there are 2 allowed millisecond chars
			int millisecondsMaxLength = 3; // max = 999

			var milliseconds = this.Value.Value.Millisecond.ToString(); // the original milliseconds give from the value
			var zeroesCount = millisecondsMaxLength - milliseconds.Length; // how many zeroes should be append before the millseconds string value

			milliseconds = new string('0', zeroesCount) + milliseconds; // append the zeroes

			// apply the milliseconds restriction given by the Mask (.ff - two symbols)
			if (milliseconds.Length > millisecondsAllowedLength)
				int charsToRemoveCount = milliseconds.Length - millisecondsAllowedLength;
				for (int i = 0; i < charsToRemoveCount; i++)
					milliseconds = milliseconds.Remove(milliseconds.Length - 1, 1);

			// replace the default parsed millseconds part of the string with the custom milliseconds
			var millisecondsIndex = text.LastIndexOf(".") + 1;
			text = text.Remove(millisecondsIndex, millisecondsMaxLength - millisecondsAllowedLength);
			text = text.Insert(millisecondsIndex, milliseconds);

		return text;

	private int GetAllowedMillisecondsLength(string mask)
		int length = 0;
		var millisecondsIndex = mask.LastIndexOf(".") + 1;
		if (millisecondsIndex != -1)
			length = mask.Length - millisecondsIndex;
		return length;
