At times, you might need to switch or load the PDF documents dynamically after the initial load operation. To achieve this, load the PDF document as a base64 string or file path in PDF Viewer control using the Load() method dynamically.
The following code example shows how to load a bas64 string dynamically.
@using Syncfusion.Blazor.PdfViewerServer
@using Syncfusion.Blazor.Buttons
<SfButton @onclick="clicked">Load Document</SfButton>
<SfPdfViewerServer DocumentPath="@DocumentPath" Height="500px" Width="1060px" @ref="Viewer"></SfPdfViewerServer>
@code{
SfPdfViewerServer Viewer;
private string DocumentPath { get; set; } = "wwwroot/Data/PDF_Succinctly.pdf";
public void clicked()
{
byte[] byteArray = System.IO.File.ReadAllBytes("wwwroot/Data/Python_Succinctly.pdf");
string base64String = Convert.ToBase64String(byteArray);
Viewer.Load("data:application/pdf;base64," + base64String, null);
}
}The following code example shows how to load the PDF dynamically by specifying file path.
@using Syncfusion.Blazor.PdfViewerServer
@using Syncfusion.Blazor.Buttons
<SfButton @onclick="clicked">Load Document</SfButton>
<SfPdfViewerServer DocumentPath="@DocumentPath" Height="500px" Width="1060px" @ref="Viewer"></SfPdfViewerServer>
@code{
SfPdfViewerServer Viewer;
private string DocumentPath { get; set; } = "wwwroot/data/PDF_Succinctly.pdf";
public void clicked()
{
Viewer.Load("wwwroot/data/Python_Succinctly.pdf", null);
}
}
