DxEditorBase.BeginUpdate() Method

Suspends component updates caused by parameter changes and method calls until the EndUpdate() method is called.

Namespace: DevExpress.Blazor.Base

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
public void BeginUpdate()

#Remarks

You can use BeginUpdate() and EndUpdate() methods to change values of the editor parameters outside the component markup.

The following code snippet changes the ReadOnly parameter value.

<DxListBox Data="forecasts"
           TextFieldName="@nameof(WeatherForecast.Summary)"
           @ref="component"
           @bind-Values="values"/>
<br/>
<DxButton Text="MakeReadOnly" Click="@MakeReadOnly"></DxButton>

@code {
    private IListBox<WeatherForecast, WeatherForecast> component;

    private IEnumerable<WeatherForecast> forecasts;
    private IEnumerable<WeatherForecast> values;

    protected override async Task OnInitializedAsync() {
        forecasts = await ForecastService.GetForecastAsync(DateOnly.FromDateTime(DateTime.Now));
    }

    void MakeReadOnly() {
        component.BeginUpdate();
        component.ReadOnly = true;
        component.EndUpdate();
    }
}
