Solution to view pdf file loaded from server based on arguments

[SaravanaRaj Sundararaj]

I have an Angular application which has the ASP.NET MVC as the server controller. I have simple requirement to view the pdf file on the browser. The use case is UI sends the fileId to the MVC controller which in turn interpretes the location of the file from the database. 

I have gone through the documentation of the PdfViewer but I couldnt find an easy working solution where in I can pass the params and pdfviewer loads the file from the server's response stream. 

So, I need your help and looking forward to find a solution with the help of your team. Thanks! and Im using Syncfusion 14.4

Hi SaravanaRaj, 

  

Thank you for using Syncfusion products. 

  

We have created a sample for loading the PDF document from the database in a Angular application with ASP.NET MVC controller. You can download the sample from the following link. 

  

https://www.syncfusion.com/downloads/support/forum/130599/ze/PdfViewer_DBSample-1178543973 

  

In the above sample, a text box is provided to enter the document id (which you have provided in the Database). On clicking the button "Load the Document", the location of the PDF document from the database will be sent as response from the MVC controller and the PDF document will be loaded in the PDF viewer control. 

  

Note: Please modify the sample based on the database that you have created. The database table has two columns "DocumentID" for id of the document and "Data" for full path of the PDF document. 

  

Please confirm us that the provided sample meets your requirements. If not, please let us know further details about your requirements. These details will be helpful for us to analyze further and assist you better.

Thanks for the sample. It solves our problem but not completely. Do I have to load a default pdf document on the initial load? Because, in our page, the initial view is blank and when user click on a node (which is on the left navigation bar), it loads the pdf doc inside the viewer.Also do I have to define the PostViewerAction in the controller class? A load call is triggered in the JS when this $("#pdfviewer").ejPdfViewer({ serviceUrl: "/PDFDemo" }); is initialized. But a call to this nethod pdfviewer.load(data) aborts the previous load request which in turn triggers postViewerAction method to be called (in the error handling function).Im still troubleshooting but if this issue rings a bell, please let us know the solution. Thanks!

Hi SaravanaRaj, 

  

Thank you for your update. 

  

Please find the details for your queries in the below table. 

  

Query	Details
Do I have to load a default pdf document on the initial load? Because, in our page, the initial view is blank and when user click on a node (which is on the left navigation bar), it loads the pdf doc inside the viewer.	We need to provide the default PDF document to the PDF viewer control in the version 14.4 during control initialization. But we have provided the support to initialize the PDF viewer control without providing the default PDF document in our latest version (i.e.15.2.0.40) of Essential Studio, the PDF viewer control renders blank when we have not provided default PDF document in the MVC controller.     We have modified the previously provided sample to version 15.2.0.40 and the PDF viewer will render blank initially(the default PDF document is not provided) in the sample. You can download the sample from the following link.     https://www.syncfusion.com/downloads/support/forum/130599/ze/PDFViewer_DBsample_15.2.0.401063243708
Also do I have to define the PostViewerAction in the controller class? A load call is triggered in the JS when this $("#pdfviewer").ejPdfViewer({ serviceUrl: "/PDFDemo" }); is initialized. But a call to this nethod pdfviewer.load(data) aborts the previous load request which in turn triggers postViewerAction method to be called (in the error handling function).	We have modified the Web API controller API’s from the product version 15.1.0.33 of Essential Studio and removed the AJAX call from the error handling function of the previous AJAX request in the PDF viewer control from the same version. Please upgrade to our latest version (i.e. 15.2.0.40) of Essential Studio to resolve this issue. You can download the latest Essential Studio setup from the following link.     https://www.syncfusion.com/forums/130361/essential-studio-2017-volume-2-release-v15-2-0-40-is-available-for-download
