DxListBox<TData, TValue>.Attributes Property

Specifies a collection of standard HTML attributes applied to the List Box.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter(CaptureUnmatchedValues = true)]
public IReadOnlyDictionary<string, object> Attributes { get; set; }

Property Value

Type	Description
IReadOnlyDictionary<String, Object>	A collection of attributes.

Remarks

To apply a standard HTML attribute to the List Box, specify the attribute’s name and its value among List Box properties in the markup. If the specified name does not match an existing List Box property name, the component passes the specified value to the Attributes collection.

You can use the Attributes collection to add List Box attributes at runtime.

If you specify the CssClass property and class attribute in the Attributes collection at the same time, the List Box applies the CssClass property value.

The code snippets below set a custom value to the List Box title attribute at design time and runtime.

Design Time

<DxListBox 
    Data="@Cities" 
    @bind-Values="@Values"
    title="A sample List Box tooltip.">
</DxListBox>

@code {
    IEnumerable<string> Cities = new List<string>() {
        "London",
        "Berlin",
        "Paris",
    };

Runtime

<DxListBox 
    Data="@Cities" 
    @bind-Values="@Values"
    Attributes="ListBoxAttributes">
</DxListBox>

@code {
    IEnumerable<string> Cities { get; set; }
    IEnumerable<string> Values { get; set; }
    Dictionary<string, object> ListBoxAttributes { get; set; } = new();

    protected override void OnInitialized() {
        Cities = new List<string>() {
            "London",
            "Berlin",
            "Paris",
        };

        ListBoxAttributes["title"] = "A sample List Box tooltip.";
    }
}
