Class ItemEventArgs<T>

Provides strongly-typed event arguments for item rendering events in list-based components.

Inheritance

System.Object

ItemEventArgs<T>

Namespace: Syncfusion.Blazor.Toolkit.Calendars

Assembly: Syncfusion.Blazor.Toolkit.dll

Syntax

public class ItemEventArgs<T> : Object

Type Parameters

Name	Description
T	The type of the item value being rendered (typically System.DateTime for time picker items).

Remarks

This class contains information about individual list items as they are rendered in dropdown components such as time pickers. It allows customization of item appearance, disabling specific items, and accessing item-specific data during the rendering process. This event is fired for each item in the dropdown list.

Examples

<SfTimePicker TValue="DateTime?" ItemRender="OnItemRender"></SfTimePicker>

@code {
    void OnItemRender(ItemEventArgs<DateTime?> args)
    {
        // Disable lunch hour (12:00 PM)
        if (args.Value?.Hour == 12 && args.Value?.Minute == 0)
        {
            args.IsDisabled = true;
        }
    }
}

Constructors

Declaration

public ItemEventArgs()

Properties

IsDisabled

Gets or sets a value indicating whether the current item should be disabled.

Declaration

public bool IsDisabled { get; set; }

Property Value

Type	Description
System.Boolean	`true` if the current item should be disabled and cannot be selected; otherwise, `false`.

Remarks

This property allows you to programmatically disable specific items during the rendering process. When set to true, the item will be displayed as disabled and cannot be selected by users. This is useful for implementing business rules such as disabling specific time slots or invalid options.

Name

Gets or sets the name of the item rendering event.

Declaration

public string Name { get; set; }

Property Value

Type	Description
System.String	A `string` value representing the event name. The default value is `null`.

Remarks

This property specifies the name identifier for the item rendering event, which can be used to identify the specific type of rendering event in scenarios where multiple event handlers are used.

Text

Gets or sets the display text for the list item.

Declaration

public string Text { get; set; }

Property Value

Type	Description
System.String	A `string` containing the text to be displayed for the item. The default value is `null`.

Remarks

This property contains the formatted text that will be displayed to users in the dropdown list. You can modify this property to customize how items appear in the list, such as adding prefixes, suffixes, or applying different formatting rules.

Value

Gets or sets the underlying value object for the list item.

Declaration

public T Value { get; set; }

Property Value

Type	Description
T	A value of type `T` representing the actual value of the list item. The default value is `default(T)`.

Remarks

This property contains the strongly-typed value that corresponds to the list item being rendered. The type is determined by the generic parameter, allowing for flexibility in different component implementations. This value is what gets selected when the user chooses this item from the list.
