Namespace: DevExpress.Blazor.Base
Assembly: DevExpress.Blazor.v24.1.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 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 a editor to a layout item’s template, use the InputId
property to associate the 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’sCaptionFor
.
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.
