DxDocumentViewer.AutoStartBuild Property

Specifies whether to start building a document automatically before the Document Viewer’s UI is rendered.

Namespace: DevExpress.Blazor.Reporting

Assembly: DevExpress.Blazor.Reporting.v25.1.JSBasedControls.dll

NuGet Package: DevExpress.Blazor.Reporting.JSBasedControls

Declaration

C#

[Parameter]
public bool AutoStartBuild { get; set; }

VB.NET

<Parameter>
Public Property AutoStartBuild As Boolean

Property Value

Type	Default	Description
Boolean	`true`	true to start building a document automatically; otherwise, false.

Remarks

In Blazor Server applications, the Web Document Viewer sends the startBuild request automatically before the Document Viewer’s UI is rendered (if there is no need to wait for parameter values in the UI). If the report has no visible parameters and you set parameter values in the ParametersInitialized event handler and call the Submit() method, the report is generated twice.

Set the AutoStartBuild property to false to disable automatic document generation:

@page "/documentviewer"

<DxDocumentViewer ReportName="TestReport" AutoStartBuild="false">
    <DxDocumentViewerCallbacks ParametersInitialized="viewerCustomization.onParametersInitialized" />
</DxDocumentViewer>
