DxSparkline.Exported Event
Fires after the Sparkline is exported.
Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v24.1.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();
}
}
