Type Parameters
Name Description
TValue

Specifies the type of the time value that the SfTimePicker component will handle. This can be System.DateTime, System.DateTime?, System.DateTimeOffset, System.DateTimeOffset?, System.TimeOnly, or System.TimeOnly?.
Remarks

The SfTimePicker component inherits from SfInputTextBase<TValue> and provides a comprehensive time selection interface. It supports various time formats, input validation, keyboard navigation, and localization features. The component can be configured to restrict time selection within specific ranges and supports both popup-based selection and direct text input.

Examples

The following example demonstrates how to create a basic SfTimePicker component:

<SfTimePicker TValue="DateTime?" @bind-Value="@selectedTime" Placeholder="Select time"></SfTimePicker>

@code {
    private DateTime? selectedTime = DateTime.Now;
}

Basic usage of TimePicker component:

<SfTimePicker TValue="DateTime" @bind-Value="selectedTime" Format="HH:mm" />

Properties

AllowEdit

Gets or sets a value indicating whether the SfTimePicker<TValue> allows users to change the value via direct typing.

Declaration
public bool AllowEdit { get; set; }
Property Value
Type Description
System.Boolean

true if the TimePicker allows users to change the value via typing; otherwise, false to restrict users to picker-only selection. The default value is true.
Remarks

When set to false, users can only select time values from the popup list and cannot type directly into the input field. This property is useful when you want to ensure that only predefined time values can be selected.

System.Collections.Generic.Dictionary<System.String, System.Object>

A dictionary of key-value pairs representing HTML attributes. The default value is null.
Remarks

Additional attributes can be added by specifying an inline attribute or by using the @attributes directive. These attributes will be applied directly to the root HTML element of the TimePicker component.

Examples

The following example shows how to add HTML attributes:

<SfTimePicker TValue="DateTime?" HtmlAttributes="@(new Dictionary<string, object> { {"class", "custom-timepicker"}, {"title", "Select time"} })"></SfTimePicker>

InputAttributes

Gets or sets additional input attributes such as disabled, value, and more to be applied to the input element of the SfTimePicker<TValue>.

Declaration
public Dictionary<string, object> InputAttributes { get; set; }
Property Value
Type Description
System.Collections.Generic.Dictionary<System.String, System.Object>

A dictionary of key-value pairs representing input attributes. The default value is an empty dictionary.
Remarks

If you configure both a component property and an equivalent input attribute, the component considers the property value over the attribute value. These attributes are applied directly to the underlying input HTML element.

Examples

The following example shows how to add input attributes:

<SfTimePicker TValue="DateTime?" InputAttributes="@(new Dictionary<string, object> { {"maxlength", "10"}, {"autocomplete", "off"} })"></SfTimePicker>

InputFormats

Gets or sets the array of input formats to be used for parsing typed time values in the SfTimePicker<TValue> component.

Declaration
public string[] InputFormats { get; set; }
Property Value
Type Description
System.String[]

An array of strings representing the acceptable input formats for time values. The default value is null.
Remarks

This property allows the SfTimePicker<TValue> to interpret typed time values using a specified array of formats. The formats can include both standard and custom time formats supported in C#. When both InputFormats and Format properties are specified, the InputFormats property takes priority for parsing. If only InputFormats is specified, parsing will be attempted using the formats provided in the array. The parsing logic prioritizes the formats in the order they are specified in the InputFormats array. If a successful parsing occurs, the SfTimePicker<TValue> updates its value accordingly. Error handling is controlled by the StrictMode property.

Examples

The following example demonstrates how to set multiple input formats for flexible time entry:

<SfTimePicker TValue="DateTime?" InputFormats='new string[] { "hh:mm", "hh mm", "hhmm", "HH:mm" }' Placeholder="Enter time"></SfTimePicker>

KeyConfigs

Gets or sets the keyboard shortcut configurations for the SfTimePicker<TValue> component.

Declaration
public Dictionary<string, object> KeyConfigs { get; set; }
Property Value
Type Description
System.Collections.Generic.Dictionary<System.String, System.Object>

A dictionary of key-value pairs representing keyboard shortcuts and their corresponding actions. The default value is null.
Remarks

This property allows customization of keyboard shortcuts for various TimePicker actions. It is particularly useful when using non-standard keyboards (such as German keyboards) or when you need to override default keyboard behaviors. The dictionary keys represent the keyboard shortcuts, and the values represent the corresponding actions.

Examples

The following example shows how to customize keyboard shortcuts:

<SfTimePicker TValue="DateTime?" KeyConfigs="@keyConfig" Placeholder="Select time"></SfTimePicker>

@code {
    Dictionary<string, object> keyConfig = new Dictionary<string, object>
    {
        { "escape", "close" },
        { "enter", "select" }
    };
}

Max

Gets or sets the maximum time value that can be selected in the SfTimePicker<TValue>.

Declaration
public DateTime Max { get; set; }
Property Value
Type Description
System.DateTime

A System.DateTime value representing the maximum selectable time. The default value is December 31, 2099, 23:59:59.
Remarks

Time values in the popup list and user input that exceed this maximum value will be disabled or rejected. Only the time portion of the DateTime value is considered; the date portion is used for internal calculations. This property works in conjunction with the Min property to define a valid time range.

Examples

The following example shows how to restrict time selection to business hours:

<SfTimePicker TValue="DateTime?" Max="new DateTime(2023, 1, 1, 18, 0, 0)" Min="new DateTime(2023, 1, 1, 9, 0, 0)" Placeholder="Business hours only"></SfTimePicker>

Min

Gets or sets the minimum time value that can be selected in the SfTimePicker<TValue>.

Declaration
public DateTime Min { get; set; }

Remarks

Time values in the popup list and user input that are below this minimum value will be disabled or rejected. Only the time portion of the DateTime value is considered; the date portion is used for internal calculations. This property works in conjunction with the Max property to define a valid time range.

Examples

The following example shows how to set a minimum time of 9:00 AM:

<SfTimePicker TValue="DateTime?" Min="new DateTime(2023, 1, 1, 9, 0, 0)" Placeholder="Select time after 9 AM"></SfTimePicker>

OpenOnFocus

Gets or sets a value indicating whether the SfTimePicker<TValue> popup opens automatically when the input field receives focus.

Declaration
public bool OpenOnFocus { get; set; }
Property Value
Type Description
System.Boolean

true if the TimePicker popup should open on input focus; otherwise, false. The default value is false.
Remarks

Use this property to improve user experience by automatically showing the TimePicker popup when the user clicks or tabs into the input field. This is particularly useful for interfaces where quick access to time selection is desirable and reduces the number of clicks required to select a time.

Examples

The following example demonstrates how to enable automatic popup opening on focus:

<SfTimePicker TValue="DateTime?" OpenOnFocus="true" Placeholder="Focus to open popup"></SfTimePicker>

Placeholder

Gets or sets the text that is shown as a hint or placeholder until the user focuses on or enters a value in the SfTimePicker<TValue>.

Declaration
public string Placeholder { get; set; }
Property Value
Type Description
System.String

A string value representing the placeholder text. The default value is null.
Remarks

The placeholder text behavior depends on the FloatLabelType property. When FloatLabelType is set to Auto, the placeholder text will float above the input when focused or when the field has a value.

Examples

The following example shows how to set a placeholder text:

<SfTimePicker TValue="DateTime?" Placeholder="Enter time (HH:mm)"></SfTimePicker>

Readonly

Gets or sets a value indicating whether the SfTimePicker<TValue> is in read-only mode, preventing user interaction.

Declaration
public bool Readonly { get; set; }
Property Value
Type Description
System.Boolean

true if the TimePicker value cannot be edited; otherwise, false. The default value is false.
Remarks

When the read-only mode is enabled, users cannot edit the time value through typing or popup interaction. The popup cannot be opened when this property is set to true.

Examples

The following example shows how to create a read-only TimePicker:

<SfTimePicker TValue="DateTime?" Readonly="true" Value="DateTime.Now"></SfTimePicker>

ScrollTo

Gets or sets the initial scroll position of the time popup list in the SfTimePicker<TValue>.

Declaration
public Nullable<DateTime> ScrollTo { get; set; }
Property Value
Type Description
System.Nullable<System.DateTime>

A nullable System.DateTime value representing the time to scroll to when the popup opens. The default value is null.
Remarks

When the popup opens, it will automatically scroll to the specified time position in the list. If the specified time is not present in the popup list (due to the Step interval), the popup will scroll to the nearest available time. If this property is null and no value is selected, the popup will show from the beginning of the time list.

Examples

The following example shows how to set the initial scroll position to 2:00 PM:

<SfTimePicker TValue="DateTime?" ScrollTo="new DateTime(2023, 1, 1, 14, 0, 0)" Placeholder="Select time"></SfTimePicker>

ShowClearButton

Gets or sets a value indicating whether the clear button is displayed in the SfTimePicker<TValue> component.

Declaration
public bool ShowClearButton { get; set; }
Property Value
Type Description
System.Boolean

true if the clear button is displayed; otherwise, false. The default value is false.
Remarks

When enabled, a clear button (×) appears on the right side of the input field, allowing users to quickly clear the selected time value. The clear button is only visible when the TimePicker has a value.

Examples

The following example shows how to enable the clear button:

<SfTimePicker TValue="DateTime?" ShowClearButton="true" Placeholder="Select time"></SfTimePicker>

Step

Gets or sets the time interval in minutes between adjacent time values in the SfTimePicker<TValue> popup list.

Declaration
public int Step { get; set; }
Property Value
Type Description
System.Int32

An integer value representing the time interval in minutes. The default value is 30.
Remarks

This property determines the granularity of time options available in the popup list. For example, a step of 30 minutes will show times like 12:00, 12:30, 1:00, 1:30, etc. A smaller step value provides more time options, while a larger step value provides fewer options. The step value should be a positive integer and a divisor of 1440 (total minutes in a day) for optimal results.

Examples

The following example shows how to set a 15-minute interval:

<SfTimePicker TValue="DateTime?" Step="15" Placeholder="Select time (15 min intervals)"></SfTimePicker>

StrictMode

Gets or sets a value indicating whether the SfTimePicker<TValue> operates in strict mode for input validation.

Declaration
public bool StrictMode { get; set; }
Property Value
Type Description
System.Boolean

true if the component should only allow valid time values within the specified range and reset invalid entries to the previous value; otherwise, false to allow invalid or out-of-range time values with error highlighting. The default value is false.
Remarks

When StrictMode is enabled, the component will automatically validate user input and reset to the previous valid value if an invalid time is entered. When disabled, invalid time values are allowed but will be highlighted with an error class, giving users visual feedback about the invalid input. This property works in conjunction with the Min and Max properties to determine valid time ranges.

Examples

The following example shows how to enable strict mode:

<SfTimePicker TValue="DateTime?" StrictMode="true" Min="new DateTime(2023, 1, 1, 9, 0, 0)" Max="new DateTime(2023, 1, 1, 17, 0, 0)" Placeholder="Business hours only"></SfTimePicker>

TabIndex

Declaration
public int TabIndex { get; set; }
Property Value
Type Description
System.Int32

An integer value representing the tab index. The default value is 0.
Remarks

The TabIndex property specifies the order in which elements receive focus when the user navigates through the page using the Tab key. A higher value indicates that the element will receive focus later in the tab order.

Examples

The following example shows how to set the tab index:

<SfTimePicker TValue="DateTime?" TabIndex="1" Placeholder="Select time"></SfTimePicker>

TimePickerEditContext

Gets or sets the edit context of the TimePicker component for form validation integration.

Declaration
protected EditContext TimePickerEditContext { get; set; }
Property Value
Type Description
Microsoft.AspNetCore.Components.Forms.EditContext

An Microsoft.AspNetCore.Components.Forms.EditContext instance that provides validation context for the TimePicker. The default value is null.
Remarks

This property is automatically populated when the TimePicker is used within a Blazor EditForm component. It enables the TimePicker to participate in form validation and track field state changes.

Width

Declaration
public string Width { get; set; }
Property Value
Type Description
System.String

A string value representing the width in CSS units (px, %, em, etc.). The default value is null.
Remarks

The width can be specified in various CSS units such as pixels (px), percentage (%), em, rem, etc. If not specified, the component will use its default width based on the applied theme.

Examples

The following example shows how to set the width of the TimePicker:

<SfTimePicker TValue="DateTime?" Width="300px" Placeholder="Select time"></SfTimePicker>

ZIndex

Gets or sets the z-index CSS property value of the SfTimePicker<TValue> popup element.

Declaration
public int ZIndex { get; set; }
Property Value
Type Description
System.Int32

An integer value representing the z-index of the popup. The default value is 1000.
Remarks

The z-index property specifies the stack order of the popup element. Higher values appear in front of elements with lower values. This property is useful when you need to ensure the TimePicker popup appears above other elements on the page, especially in complex layouts with overlapping elements.

Examples

The following example shows how to set a higher z-index for the popup:

<SfTimePicker TValue="DateTime?" ZIndex="2000" Placeholder="Select time"></SfTimePicker>
