DxListBox<TData, TValue>.SearchBoxInputDelay Property
Specifies the delay between the last input in the search box and when the list box displays matching values.
Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v25.1.dll
NuGet Package: DevExpress.Blazor
Declaration
[Parameter]
public int SearchBoxInputDelay { get; set; }Property Value
| Type | Description |
|---|---|
| Int32 | The delay in milliseconds. |
Remarks
If the ShowSearchBox property is enabled, a search box appears above the list box. When a user enters text into this search box, the list automatically filters to show matching items and highlights the search term within the found items.
Use the SearchBoxInputDelay property to specify the time between the last update of the search field and the subsequent update of the list box. If the search input changes during the delay, the timer restarts. This is useful for limiting frequent list updates and reducing associated data requests (such as database queries or REST API calls) while the user types.
The list box updates immediately if the user presses the Enter key or moves focus away from the search field.
<DxListBox Data="Data.Stars.Alpha"
@bind-Values="SelectedValues"
ShowSearchBox="true"
SearchBoxInputDelay="1000" />
@code {
IEnumerable<string> SelectedValues { get; set; } = Data.Stars.Alpha.Take(1);
}
