Steps to reproduce:

radDateTimePicker1.Value = DateTime.Today; 
radDateTimePicker1.SetToNullValue(); 
radDateTimePicker1.Value = DateTime.Today;

If assign a value using a percent mask the value isn't displayed as it should - assign a value of 0.08 I expect the control to display  "8.00 %", instead it displays "0.08 %"

Use the TextChanged event instead

The RadMaskedEditBox wil throw an exception if set the custom culture with empty CurrencySymbol and MaskType is set to Numeric. 

Workaround:
Set the CurrencySimbol to space char:

            cultureInfo.NumberFormat.CurrencySymbol = " "
            this.radMaskedEditBox1.Culture = cultureInfo

When NumberFormat.NumberDecimalSeparator is same with NumberFormat.CurrencyGroupSeparator   numbers cannot be edited and deleted.
As a workaround set these separators to different values.

If I set a RadSpinEditor.Hexadecimal to true, then false without reading the value, the value will steadily increase.

Workaround:
    public class MySpinEditor : RadSpinEditor
    {
        public new bool Hexadecimal
        {
            get
           

When users select the "Ignore All" on the certain word the other ocupation of this word still market as wrong.

If you set MaskType to Standard and Mask to  ">LLL_LLL_LLL"   and set the TextMaskFormat property to ExcludePromptAndLiterals, the result value property will be an empty string.

NullabeValue property is set to 1/1/0001 instead of NULL when user delete the date and date is equal to NullDate.

It's not possible to set using code not UI the RadTimePicker.Value when RadTimePicker.ReadOnly = true

RadDateTimePicker/RadDateTimePickerElement should display empty text if the Value property is set to null.

Fix: RadMaskedEditBox MaskedType Numeric Mask "D" allows to enter only one digit
Workaround: Change RadMaskedEditBox Mask from "D" to "D0"

Keyboard input does not work in RadDateTimePicker when the Culture is ar-SA

For example: users should be able to enter date like this 31/02/2013 and when control lost the focus the date should convert to 28/02/2013

Resolution:
This behavior could be achieved with the new FreeFormDateTimeProvider. Whit this provider user is not restricted from any mask and could enter the date in desire format. This provider is integrated in RadMakedEditBox so it can be used in RadDateTimePicker and RadTimePicker. To change default provider of RadDateTimePicker you should change the mask type of embedded RadMaskEditBox into RadDateTimePicker. For Example:

 this.radDateTimePicker1.DateTimePickerElement.TextBoxElement.MaskType = MaskType.FreeFormDateTime; 

RadTimePicker/RadTimePickerElement should display empty text or Null text if the Value property is set to null.

Workaround:
        Me.RadTimePicker1.NullText = "Please, enter a time!"
        Me.RadTimePicker1.Value = Nothing
        Me.RadTimePicker1.TimePickerElement.MaskedEditBox.TextBoxItem.Text = ""

Add a possibility to suggest misspelled words if they are all capital letters or contains numbers.

RadMaskedEditBox should be able to handle dynamic masks. The core of this feature is the ability to have a value for the number of allowed characters on one hand and a value for the number of maximum characters on the other hand.

RadMarkupDialog should provide the possibility to be localized by a localization providers.

If you have a GridViewMaskBoxColumn with MaskType set to E-mail and you try to enter and commit a value in this column, you get an exception.

The sender of RadDateTimePicker.KeyPress event is currently HostedTextBoxBase which is not the correct sender to expose.
