DxDropDownBox.ValueChanged Event

Fires when the editor value changes.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public EventCallback<object> ValueChanged { get; set; }

Parameters

Type	Description
Object	Editor value.

Remarks

Handle the ValueChanged event to respond to the Value change. The ValueChanged event is handled automatically when you use two-way data binding for the Value property (@bind-Value).

Note

If you add a DxDropDownBox to an EditForm component and use one-way binding for the Value property, you need to specify the ValueExpression property.

<DxDropDownBox Value="@Value" ValueChanged="@((object newValue) => OnValueChanged(newValue))" ... />

@code {
    object Value { get; set; }

    void OnValueChanged(object newValue) {
      Value = newValue;
      // ...
    }
}
