DxCheckBox<T>.InputId Property

Specifies a unique identifier (ID) of the CheckBox’s input element.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v20.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public string InputId { get; set; }

Property Value

Type	Description
String	A unique identifier.

Remarks

The InputId property value is assigned to the id attribute of the CheckBox’s input element. The id is case-sensitive, should contain at least one character, and should not contain whitespaces (spaces, tabs, etc.)

When you create a Form Layout component and add a CheckBox to a layout item’s template, use the InputId property to associate the CheckBox with the layout item’s caption.

• Specify the layout item’s Caption property. A browser renders the caption as an HTML label element.
• Set the layout item’s CaptionFor property to a unique value. This value is assigned to the label’s for attribute.
• Set the editor’s InputId property to the same value as the item’s CaptionFor.

Note

If you do not specify the CaptionFor property, the Form Layout generates a random identifier (GUID) and assigns it to the label’s for attribute and to the id property of the first input element in the template.

<DxFormLayout>
    @*...*@
    <DxFormLayoutItem Caption="On Vacation:" CaptionFor="check_box">
        <Template>
            <DxCheckBox @bind-Checked="@OnVacation" InputId="check_box"></DxCheckBox>
        </Template>
    </DxFormLayoutItem>
</DxFormLayout>

@code {
    // ...
    bool OnVacation { get; set; } = true;
}

You can click the associated label to focus/check/uncheck the checkbox.
