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

A possibility to specify the default time (to be different from 00:00) when choosing date value from the drop-down calendar.

Add option to RadSpellChecker which will allow you to append the newly added words to the loaded dictionary and save them on the hard drive.

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.

RadMaskEditBox - When MaskType is Numeric and Mask is currency ("C") pasting a value (9.99) results in 09.99.00

Users should be able to increment the whole value of the RadMaskedEditBox using the Up/Down arrow keys or Mouse Wheel

To reproduce:
this.radDateTimePicker1.DateTimePickerElement.TextBoxElement.MaskType = MaskType.FreeFormDateTime;

And try pasting a date, or some free text.

 

The Free Form Date Time Parsing of a RadTimePicker is not able to recognize "hhmm" as an legit value (ex. 1030 for half pas ten).

This improvement could be nice, as it is a common way to write an time. It is working in Outlook Appointement Form.

Workaround:
((RadDateTimePickerCalendar)this.dtpFromTaarich.DateTimePickerElement.GetCurrentBehavior()).Calendar.Navigating +=
               new CalendarNavigatingEventHandler(dtp_Navigating);
 
void dtp_Navigating(object sender, Telerik.WinControls.UI.CalendarNavigatingEventArgs e)
       {
           if (e.Direction == Telerik.WinControls.UI.CalendarNavigationDirection.Forward)
           {
               if (!e.IsFastNavigation)
                   e.StartDate = (sender as RadCalendar).CalendarElement.View.ViewStartDate.AddMonths(-1);
               else
                   e.StartDate = (sender as RadCalendar).CalendarElement.View.ViewStartDate.AddMonths(-12);
           }
           else if (!e.IsFastNavigation)
           {
               e.StartDate = (sender as RadCalendar).CalendarElement.View.ViewStartDate.AddMonths(1);
           }
           else e.StartDate = (sender as RadCalendar).CalendarElement.View.ViewStartDate.AddMonths(12);
       }

Resolution: You need to set the RightToLeft property to Yes of CalendarBehavior
RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
RadCalendar calendar = calendarBehavior.Calendar as RadCalendar;
calendar.RightToLeft = System.Windows.Forms.RightToLeft.Yes;

Note: when you open the spell check dialog  and it iterates through the words, it does not highlight (select) the word in the linked RadTextBoxControl/RadTextBox, like it does in the Word's spell checker. 

It will be nice if there is a TextAlign property at control level for RadMaskedEditBox.

Users should be able to insert the decimal separator character of the current culture by pressing the '.' (dot) char from the numeric pad.

ADD. RadMaskedEditBox - add functionality to get the value of the control without the literals contained or the prompt chars

One should be able to disable the saving of the custom colors. In addition one should be able to override the color dialog FormClosing method.

RadMaskedEditBox does not appear as a choice in the data source list of bound controls.

RadAutoCompleteBox - Items collection ordered by input, not alphabetically

When the IP is set like this:
this.radMaskedEditBox1.Value = "89.111.222.123";
the value in the box is not correct:
891.112.221.23

In addition the user should be able to insert digits not just replace them.
