Check the status of annotations or comments in Blazor SfPdfViewer
1 Oct 20252 minutes to read
The Syncfusion Blazor SfPdfViewer component supports retrieving the review status of annotations and comments through the Review property of the PdfAnnotation class. This enables identifying the State (for example, Accepted, Rejected) and the StateModel (for example, Review, Comment) associated with each annotation.
The following code example shows how to obtain the review status of each annotation and log it to the browser console.
@using Syncfusion.Blazor.SfPdfViewer
@using Syncfusion.Blazor.Buttons
@inject IJSRuntime JsRuntime;
<SfButton OnClick="reviewStatus">Review Status</SfButton>
<SfPdfViewer2 @ref="pdfviewer"
CommentPanelVisible="true"
DocumentPath="@DocumentPath"
Height="100%"
Width="100%"></SfPdfViewer2>
@code{
private string DocumentPath { get; set; } = "wwwroot/Data/PDF_Succinctly.pdf";
SfPdfViewer2 pdfviewer;
//Prints the comment status of the PDF document in console.
public async void reviewStatus()
{
//Gets the annotation collection.
List<PdfAnnotation> annotationCollection = await pdfviewer.GetAnnotationsAsync();
for (var x = 0; x < annotationCollection.Count; x++)
{
PdfAnnotation annotation = annotationCollection[x];
//Gets the review status details of the comment.
Review review = annotation.Review;
var reviewState = review.State;
var reviewStateModel = review.StateModel;
await this.JsRuntime.InvokeVoidAsync("console.log",reviewState.ToString());
}
}
}
