DxDropDownListEditorBase<TData, TValue>.InputId Property

Specifies a unique identifier (ID) of an editor’s input element.

Namespace: DevExpress.Blazor.Base

Assembly: DevExpress.Blazor.v24.2.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 an editor’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 an editor to a layout item’s template, use the InputId property to associate the an editor 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.
