Windows forms numericupdown value

Элемент NumericUpDown представляет пользователю выбор числа из определенного диапазона. Для определения диапазона чисел для выбора NumericUpDown имеет два свойства: Minimum (задает минимальное число) и Maximum (задает максимальное число).

Само значение элемента хранится в свойстве Value :

По умолчанию элемент отображает десятичные числа. Однако если мы установим его свойство Hexadecimal равным true , то элемент будет отображать все числа в шестнадцатеричной системе.

Даже если мы в коде установим обычное десятичное значение:

то элемент все равно отобразит его в шестнадцатиричной системе.

Если мы хотим отображать в поле дробные числа, то можно использовать свойство DecimalPlaces , которое указывает, сколько знаков после запятой должно отображаться. По умолчанию это свойство равно нулю.

Также можно задать отображение тысячного разделителя. Для этого для свойства ThousandsSeparator надо установить значение true . Например, numericUpDown при Value=1000,03 , DecimalPlaces=2 и ThousandsSeparator=true :

При этом надо учитывать, что если мы устанавливаем значение для свойства Value в окне свойств, то там в качестве разделителя цеой и дробной части используется запятая. Если же мы устанавливаем данное свойство в коде, тогда в качестве разделителя используется точка.

По умолчанию при нажатии на стрелочки вверх-вниз на элементе значение будет увеличиваться, либо уменьшаться на единицу. Но с помощью свойства Increment можно задать другой шаг приращения, в том числе и дробный.

При работе с NumericUpDown следует учитывать, что его свойство Value (как и свойства Minimum и Maximum ) хранит значение decimal. Поэтому в коде мы также должны с ним работать как с decimal, а не как с типом int или double.

DomainUpDown

Элемент DomainUpDown предназначен для ввода текстовой информации. Он имеет текстовое поле для ввода строки и две стрелки для перемещения по списку строк:

Список для DomainUpDown задается с помощью свойства Items . Список можно сразу упорядочить по алфавиту. Для этого надо свойству Sorted присвоить значение true .

Чтобы можно было циклично перемещаться по списку, то есть при достижении конца или начала списка его просмотр начинался с первого или последнего элемента, надо установить для свойства Wrap значение true .

В коде выбранное значение в DomainUpDown доступно через свойство Text. Например, добавим программно список строк в DomainUpDown и обработаем изменение выбора в списке:

Для обработки изменения текста здесь таке, как и для элемента TextBox, можно использовать событие TextChanged , в обработчике которого мы выводим выбранный текст в сообщение.

Элемент управления NumericUpDown (Windows Forms) NumericUpDown Control (Windows Forms)

Элемент управления Windows Forms NumericUpDown выглядит как сочетание текстового поля и пары кнопок со стрелками для корректировки значения пользователем. The Windows Forms NumericUpDown control looks like a combination of a text box and a pair of arrows that the user can click to adjust a value. Он выводит и задает отдельное числовое значение из списка вариантов. The control displays and sets a single numeric value from a list of choices. Пользователь может увеличить и уменьшить число путем нажатия кнопок со стрелками, клавиш со стрелками ВВЕРХ и ВНИЗ или путем ввода числа. The user can increase and decrease the number by clicking up and down buttons, by pressing the UP and DOWN ARROW keys, or by typing a number. Нажатие клавиши со стрелкой ВВЕРХ увеличивает значение до максимума; нажатие клавиши со стрелкой ВНИЗ уменьшает значение до минимума. Clicking the UP ARROW key moves the value toward its maximum; clicking the DOWN ARROW key moves the position toward the minimum. В качестве примера сферы применения этого элемента управления можно привести регулятор громкости музыкального проигрывателя. An example where this kind of control might be useful is for a volume control on a music player. Числовые элементы управления «вверх/вниз» используются в некоторых приложениях панели управления Windows. Numeric up-down controls are used in some Windows control panel applications.

Практическое руководство. Ввод числовых значений с помощью элемента управления NumericUpDown в Windows Forms How to: Set and Return Numeric Values with the Windows Forms NumericUpDown Control

Числовое значение NumericUpDown элемента управления Windows Forms определяется его Value свойством. The numeric value of the Windows Forms NumericUpDown control is determined by its Value property. Можно писать условные тесты для значения элемента управления точно так же, как и любое другое свойство. You can write conditional tests for the control’s value just as with any other property. После Value задания свойства его можно настроить непосредственно, написав код для выполнения операций с ним, или можно вызвать UpButton DownButton методы и. Once the Value property is set, you can adjust it directly by writing code to perform operations on it, or you can call the UpButton and DownButton methods.

Задание числового значения To set the numeric value

Присвойте значение Value свойству в коде или в окно свойств. Assign a value to the Value property in code or in the Properties window.

Вызовите UpButton метод или, DownButton чтобы увеличить или уменьшить значение на величину, указанную в Increment свойстве. Call the UpButton or DownButton method to increase or decrease the value by the amount specified in the Increment property.

Получение числового значения To return the numeric value

Доступ к Value свойству в коде. Access the Value property in code.

Numeric UpDown. Value Свойство

Определение

Возвращает или задает значение, назначенное регулятору (также известному как элемент управления «вверх-вниз»). Gets or sets the value assigned to the spin box (also known as an up-down control).

Значение свойства

Численное значение элемента управления NumericUpDown. The numeric value of the NumericUpDown control.

Исключения

Присвоенное значение меньше значения свойства Minimum. The assigned value is less than the Minimum property value.

-или- -or- Присвоенное значение больше значения свойства Maximum. The assigned value is greater than the Maximum property value.

Примеры

В следующем примере кода создается и инициализируется NumericUpDown элемент управления, устанавливаются некоторые его общие свойства и пользователь имеет возможность изменять некоторые из этих свойств во время выполнения. The following code example creates and initializes a NumericUpDown control, sets some of its common properties, and allows the user to change some of these properties at run time. В этом коде предполагается, что CheckBox в форму были помещены три элемента управления и созданы обработчики для их Click событий. This code assumes three CheckBox controls have been placed on a form and handlers for their Click events have been instantiated. DecimalPlacesСвойства, ThousandsSeparator и Hexadecimal задаются для Click события каждого флажка. The DecimalPlaces, ThousandsSeparator, and Hexadecimal properties are set on the Click event of each check box.

Комментарии

Если Value свойство задано, новое значение проверяется между Minimum Maximum значениями и. When the Value property is set, the new value is validated to be between the Minimum and Maximum values. После этого UpdateEditText вызывается метод для обновления экрана регулятора новым значением в соответствующем формате. Following this, the UpdateEditText method is called to update the spin box’s display with the new value in the appropriate format.

Numeric UpDown Class

Definition

Represents a Windows spin box (also known as an up-down control) that displays numeric values.

Examples

The following code example creates and initializes a NumericUpDown control, sets some of its common properties, and allows the user to change some of these properties at run time. This code assumes three CheckBox controls have been placed on a form and handlers for their Click events have been instantiated. The DecimalPlaces, ThousandsSeparator, and Hexadecimal properties are set on the Click event of each check box.

Remarks

A NumericUpDown control contains a single numeric value that can be incremented or decremented by clicking the up or down buttons of the control. The user can also enter in a value, unless the ReadOnly property is set to true .

The numeric display can be formatted by setting the DecimalPlaces, Hexadecimal, or ThousandsSeparator properties. To display hexadecimal values in the control, set the Hexadecimal property to true . To display a thousands separator in decimal numbers when appropriate, set the ThousandsSeparator property to true . To specify the number of digits displayed after the decimal symbol, set the DecimalPlaces property to the number of decimal places to display.

To specify the allowable range of values for the control, set the Minimum and Maximum properties. Set the Increment value to specify the value to be incremented or decremented to the Value property when the user clicks the up or down arrow buttons. You can increase the speed that the control moves through numbers when the user continuously presses the up or down arrow by setting the Accelerations property.

When the UpButton or DownButton methods are called, either in code or by the click of the up or down buttons, the new value is validated and the control is updated with the new value in the appropriate format. Specifically, if the UserEdit property is set to true , the ParseEditText method is called prior to validating or updating the value. The value is then verified to be between the Minimum and Maximum values, and the UpdateEditText method is called.

Starting with the .NET Framework 4.6, the NumericUpDown control will be resized based on the system DPI setting when the app.config file contains the following entry:
