The behavior of the control can be defined by setting up some important properties as well as by handling events.
RadMaskedEditBox descends from RadTextBox and so has the same properties, methods and events. The significant properties unique to RadMaskedEditBox are:
MaskType: This property determines how masks are interpreted by the control. Valid values are:
None: The control acts like a text box.
Standard: You can define standard masks
Regex: You can define Regex expressions as masks.
IP: Predefined mask for IP input.
Email: Predefined mask for email validation.
DateTime: Predefined mask for DateTime input.
TimeSpan: Predefined mask for TimeSpan input. Available since R1 2019.
FreeFormatDateTime: With that mask type end-users are able to enter a date and time in a wide range of formats without having to conform to a specific mask. In the following article you can find more information how this DateTime parsing logic works: Parsing Dates
Mask: A string of characters that constrain user input. The Mask property may contain literals and special mask characters. The MaskType determines how the mask characters are interpreted. Use the backslash "\" character to escape any mask characters so that they display as literals. At runtime, any blank space occupied by a Mask character is displayed as the PromptChar property character.
PromptChar: This property represents the character displayed in any blank space defined by a Mask character. By default the character is an underscore "_".
Culture: This property allows you to set the current language and culture from a drop down list at design-time or assign a new CultureInfo instance at run-time.
this.radMaskedEditBox1.MaskType = Telerik.WinControls.UI.MaskType.DateTime; this.radMaskedEditBox1.Mask = "d"; this.radMaskedEditBox1.Culture = new System.Globalization.CultureInfo("de-de");
Me.RadMaskedEditBox1.MaskType = Telerik.WinControls.UI.MaskType.DateTime Me.RadMaskedEditBox1.Mask = "D" Me.RadMaskedEditBox1.Culture = New System.Globalization.CultureInfo("de-DE")
Value: This property returns user input without the formatting characters. If you want the input and the formatting characters, use the Text property.
NullText: determines the text that will be displayed, when the Value of the control is null.
RadMaskedEditBox allows you to handle ValueChanging and ValueChanged events. Examine the Text and Value properties to determine user entry with mask and without mask, respectively. ValueChanging also passes a CancelEventArgs parameter containing a Cancel property. When Cancel is set to true the value is not allowed to change.
|MaskType||Mask||User Input||Displayed as Example|
|Standard||# ###||12||# 12_|
|DateTime||d||1 1 2007||01/01/2007|
