DxTagBox<TData, TValue>.InputId Property

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

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v21.1.dll

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 TagBox’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 TagBox to a layout item’s template, use the InputId property to associate the TagBox 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="Position:" CaptionFor="tag_box">
        <Template>
            <DxTagBox Data="@(new List<string>() { "Sales Representative", "Designer", "System Administrator" })"
                        TData="string"
                        TValue="string"
                        InputId="tag_box" />
        </Template>
    </DxFormLayoutItem>
    @*...*@
</DxFormLayout>

You can click the associated label to focus the TagBox and invoke the drop-down list.
