V25.1
  • DxSparkline.Exported Event

    Fires after the Sparkline is exported.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    [Parameter]
    public EventCallback Exported { get; set; }

    Remarks

    When you call the ExportToAsync(String, DataExportFormat) method, the Sparkline exports its data and raises the Exported event.

    The following code snippet handles the Exported event to display information about the exported file:

    @inject IJSRuntime JSRuntime
    
    <DxSparkline Data="@DataSource"
                 @ref=@Sparkline
                 ArgumentFieldName="Month"
                 ValueFieldName="VisitorCount"
                 Exported="OnExported"
                 Height="50px"
                 Width="200px">
    </DxSparkline>
    
    
    <DxButton Text="Export to PDF" Click="ExportToPdf" />
    
    @code {
        DxSparkline Sparkline;
        string fileName = "Custom PDF";
    
        async Task ExportToPdf() {
            await Sparkline.ExportToAsync(fileName, DataExportFormat.Pdf);
        }
        async Task OnExported() {
            await JSRuntime.InvokeVoidAsync("alert", $"The Sparkline is exported to the {fileName} file.");
        }
    
        IEnumerable<SparklineDataPoint> DataSource = Enumerable.Empty<SparklineDataPoint>();
        protected override void OnInitialized() {
            DataSource = GenerateData();
        }
    }
