The Appearance property of an object is used to associate the object with an Appearance object that will determine its appearance. The Appearance object has properties that control settings such as color, borders, font, transparency, etc. For many of the objects in the UltraWinSchedule, you do not set formatting properties directly. Instead, you set the properties of an Appearance object, which controls the formatting of the object it is attached to.
There are two ways of working with the Appearance property and assigning the attributes of an SSAppearance object to other objects. One way is to create a new Appearance object, adding it directly to the Appearances collection. Then you assign the new Appearance object to the Appearance property of the object you want to format. This method uses a "named" Appearance object that you must explicitly create (and to which you must assign property settings) before it can be used. For instance, you could create an object in the control's Appearances collection and assign it some values as follows:
UltraTextEditor1.Appearances.Add "New1"
UltraTextEditor1.Appearances("New1").BorderColor = Color.Blue
UltraTextEditor1.Appearances("New1").ForeColor = Color.Red
Creating the object in this way does not apply formatting to any visible part of the control. The object simply exists in the collection with its property values, waiting to be used. To actually use the object, you must assign it to the control's (or another object's) Appearance property:
UltraTextEditor1.Appearance = UltraTextEditor1.Appearances("New1")
In this case, only one Appearance object exists. The control's appearance is governed by the settings of the "New1" object in the collection. Any changes you make to the object in the collection will immediately be reflected in the control.
The second way of working with the Appearance property is to use it to set property values directly, such as:
UltraTextEditor1.Appearance.ForeColor = Color.Blue
In this case, an Appearance object is automatically created by the control. This Appearance object is not a member of an Appearances collection and it does not have a name. It is specific to the object for which it was created; it is an "intrinsic" Appearance object. Changes to the properties of an intrinsic Appearance object are reflected only in the object to which it is attached.
Note that you can assign properties from a named Appearance object to an intrinsic Appearance object without creating a dependency relationship. For example, the following code...
UltraTextEditor1.Appearance.ForeColor = UltraTextEditor1.Appearances("New1").ForeColor
...does not establish a relationship between the foreground color of the intrinsic object and that of the named object. It is simply a one-time assignment of the named object's value to that of the intrinsic object. In this case, two Appearance objects exist - one in the collection and one attached to the control - and they operate independently of one another.
If you wish to assign all the properties of a named object to an intrinsic object at once without creating a dependency relationship, you can use the Clone method of the Appearance object to duplicate its settings and apply them. So if you wanted to apply all the property settings of the named Appearance object "New1" to the control's intrinsic Appearance object, but you did not want changes made to "New1" automatically reflected in the control, you would use the following code:
UltraTextEditor1.Appearance = UltraTextEditor1.Appearances("New1").Clone
Note that the properties of an Appearance object can also operate in a hierarchical fashion. Certain properties can be set to a "use default" value, which indicates to the control that the property should take its setting from the object's parent. This functionality is enabled by default, so that unless you specify otherwise, child objects resemble their parents, and formatting set at higher levels of the control hierarchy is inherited by objects lower in the hierarchy.

The KeyActionMappings property provides access to the control's mechanism for handling keyboard input from users. All keystrokes for actions such as selection, navigation and editing are stored in a table-based system that you can examine and modify using this property. Through the KeyActionsMappings property, you can customize the keyboard layout of the control to match your own standards for application interactivity.
For example, if you wanted users to be able to navigate between cells by pressing the F8 key, you could add this behavior. You can specify the key code and any special modifier keys associated with an action, as well as determine whether a key mapping applies in a given context.

| {double:i.f:c} | {double:i.f:c} is a place holder for a mask that allows floating point input where i and f in i.f specify the number of digits in the integer and fraction portions respectively.

For example, with :c in the mask, in order to enter 12.34 the user types in "1234". Notice that the decimal separator character is missing.

This property is used to determine how mask literals and prompt characters are applied to the value returned by the Value property of the control. Based on the setting of this property, the text returned by the Value property will contain no prompt characters or literals (just the raw data), the data and just the literals, the data and just the prompt characters, or all the text including both prompt characters and literals. The formatted spacing of partially masked values can be preserved by indicating to include literals with padding, which includes data and literal characters, but replaces prompt characters with spaces.
Generally, simply the raw data is returned by the Value property and data masking is used to format the data when it is displayed. In some cases, however, it may be appropriate in your application to include mask literals as well as data.

The default setting for BorderStyle is 'Raised'.
The Appearance property of an object is used to associate the object with an Appearance object that will determine its appearance. The Appearance object has properties that control settings such as color, borders, font, transparency, etc. For many of the objects in the UltraWinSchedule, you do not set formatting properties directly. Instead, you set the properties of an Appearance object, which controls the formatting of the object it is attached to.
There are two ways of working with the Appearance property and assigning the attributes of an SSAppearance object to other objects. One way is to create a new Appearance object, adding it directly to the Appearances collection. Then you assign the new Appearance object to the Appearance property of the object you want to format. This method uses a "named" Appearance object that you must explicitly create (and to which you must assign property settings) before it can be used. For instance, you could create an object in the control's Appearances collection and assign it some values as follows:
UltraNumericEditor1.Appearances.Add "New1"
UltraNumericEditor1.Appearances("New1").BorderColor = Color.Blue
UltraNumericEditor1.Appearances("New1").ForeColor = Color.Red
Creating the object in this way does not apply formatting to any visible part of the control. The object simply exists in the collection with its property values, waiting to be used. To actually use the object, you must assign it to the control's (or another object's) Appearance property:
UltraNumericEditor1.Appearance = UltraNumericEditor1.Appearances("New1")
In this case, only one Appearance object exists. The control's appearance is governed by the settings of the "New1" object in the collection. Any changes you make to the object in the collection will immediately be reflected in the control.
The second way of working with the Appearance property is to use it to set property values directly, such as:
UltraNumericEditor1.Appearance.ForeColor = Color.Blue
In this case, an Appearance object is automatically created by the control. This Appearance object is not a member of an Appearances collection and it does not have a name. It is specific to the object for which it was created; it is an "intrinsic" Appearance object. Changes to the properties of an intrinsic Appearance object are reflected only in the object to which it is attached.
Note that you can assign properties from a named Appearance object to an intrinsic Appearance object without creating a dependency relationship. For example, the following code...
UltraNumericEditor1.Appearance.ForeColor = UltraNumericEditor1.Appearances("New1").ForeColor
...does not establish a relationship between the foreground color of the intrinsic object and that of the named object. It is simply a one-time assignment of the named object's value to that of the intrinsic object. In this case, two Appearance objects exist - one in the collection and one attached to the control - and they operate independently of one another.
If you wish to assign all the properties of a named object to an intrinsic object at once without creating a dependency relationship, you can use the Clone method of the Appearance object to duplicate its settings and apply them. So if you wanted to apply all the property settings of the named Appearance object "New1" to the control's intrinsic Appearance object, but you did not want changes made to "New1" automatically reflected in the control, you would use the following code:
UltraNumericEditor1.Appearance = UltraNumericEditor1.Appearances("New1").Clone
Note that the properties of an Appearance object can also operate in a hierarchical fashion. Certain properties can be set to a "use default" value, which indicates to the control that the property should take its setting from the object's parent. This functionality is enabled by default, so that unless you specify otherwise, child objects resemble their parents, and formatting set at higher levels of the control hierarchy is inherited by objects lower in the hierarchy.
You should use the Appearance's BackColor property to set the background color of the control. The
The setting of this property will be passed through to the BackColor property of control's Appearance object.
You should use the Appearance's BackgroundImage property to set the background color of the control. The

When inputting data, the user can only replace a placeholder with a character that is of the same type as the one specified in the input mask. If the user enters an invalid character, the control rejects the character. The control can distinguish between numeric and alphabetic characters for validation, but cannot validate for valid content, such as the correct month or time of day.
The input mask can consist of the following characters:
Character | Description |
| : | Time separator. The actual character used is the one specified as the time separator by the system's international settings. This character is treated as a literal for masking purposes |
| / | Date separator. The actual character used is the one specified as the date separator by the system's international settings. This character is treated as a literal for masking purposes. |
| mm, dd, yy | Combination of these three special tokens can be used to define a date mask. mm for month, dd for day, yy for two digit year and yyyy for four digit year. Examples: mm/dd/yyyy, yyyy/mm/dd, mm/yy. |
| hh, mm, ss, tt | Combination of these three special tokens can be used to define a time mask. hh for hour, mm for minute, ss for second, and tt for AP/PM. Examples: hh:mm, hh:mm tt, hh:mm:ss. |
| {date} | {date} token is a place holder for short date input. The date mask is derived using the underlying culture settings. |
| {time} | {time} token is a place holder for short time input. Short time typically does not include the seconds portion. The time mask is derived using the underlying culture settings. |
| {longtime} | {longtime} token is a place holder for long time input. Long time typically includes the seconds portion. The long time mask is derived using the underlying culture settings. |
| Literal | All other symbols are displayed as literals; that is, they appear as themselves. |

When the control's value is null (Nothing in VB), the control displays an empty string by default. The NullText property enables the end developer to change the text that is displayed for null values (for example, '(NULL)' or '(none)').
Note: Because the control requires a prompt character to indicate unpopulated mask positions, the PromptChar property cannot be set to the null character ('\x00'). If the property is set to the null character, the value will be changed to the space character ('\x32') instead.
When the user enters text in the UltraDateTimeEditor, then the control will validate that text when in the Leave or Validating events. If the text cannot be converted to a valid date, the control must revert the value to a valid date. This property determines whether the control will use the last valid date that was entered as the user typed, or the the original value when the control was entered.
An exception is thrown if the DateTime is set to a value that is outside the range determined by the
The IsDateValid property can be used to determine if the date to which the control's
The IsDateValid property is available only at runtime.
When the control's dropdown button is clicked, a calendar is displayed. Its selected date is preset to the date in the edit portion, or, if no valid date is set, the current date. When the control's dropdown calendar closes up, the edit portion is set to display the date that was selected in the calendar portion. The DropDownCalendarAlignment property determines which side of the control the dropdown calendar will be aligned with.
The Appearance property of an object is used to associate the object with an Appearance object that will determine its appearance. The Appearance object has properties that control settings such as color, borders, font, transparency, etc. For many of the objects in the UltraWinSchedule, you do not set formatting properties directly.

This method uses a "named" Appearance object that you must explicitly create (and to which you must assign property settings) before it can be used. For instance, you could create an object in the control's Appearances collection and assign it some values as follows:
UltraDateTimeEditor1.Appearances.Add "New1"
UltraDateTimeEditor1.Appearances("New1").BorderColor = Color.Blue
UltraDateTimeEditor1.Appearances("New1").ForeColor = Color.Red
Creating the object in this way does not apply formatting to any visible part of the control. The object simply exists in the collection with its property values, waiting to be used. To actually use the object, you must assign it to the control's (or another object's) Appearance property:
UltraDateTimeEditor1.Appearance = UltraDateTimeEditor1.Appearances("New1")
In this case, only one Appearance object exists. The control's appearance is governed by the settings of the "New1" object in the collection. Any changes you make to the object in the collection will immediately be reflected in the control.

Character | Description |
| {double:i.f:c} | {double:i.f:c} is a place holder for a mask that allows floating point input where i and f in i.f specify the number of digits in the integer and fraction portions respectively. The :c portion of the mask is optional and it specifies that the inputting of the value should be done continous across fraction and integer portions. For example, with :c in the mask, in order to enter 12.34 the user types in "1234". Notice that the decimal separator character is missing. This allevietes the user from having to type in the decimal separator. |

The UIElement property returns a reference to the UIElement that represents the control itself. All the UI aspects of the control are implemented as UIElements which are children of the control's UIElement (available only at runtime).
Note: Setting the AutoCloseUpOnEquals property to true does not cause the dropdown to close up when the "=" button is clicked.
Also note that the dropdown closes when the Enter/Return key is pressed, regardless of the value of the AutoCloseUpOnEquals property.
This can be prevented by handling the control's KeyDown event for the Enter/Return key and setting the 'Handled' property of the event arguments to true.
