Open PDF new browser tab ASP.net 2.0

Question

I am trying to open a PDF in a new tab in the browser. So far I have been able to get the PDF in the browser within the "same" page. However I would now like it to open it in a new tab. However I am stuck on how to achieve this?

            Response.Clear()
            Response.ClearContent()
            Response.ClearHeaders()
            Response.ContentType = "application/pdf"
            Response.AddHeader("Content-Disposition", "inline;filename=" + strFileId & fileExtension)
            Response.AddHeader("Content-Length", bytesReturned.Length.ToString())
            Response.OutputStream.Write(bytesReturned, 0, bytesReturned.Length)
            Response.Flush()
            Response.End()

Result: enter image description here

The result is displayed in a gridview, I would like to link each "view" button to a target"_blank" attribute. The "ID" corresponds to the file name.

From my research, I can see you can add a button in the aspx page and give it target "_blank" attribute but I am not sure how to link it to my displayPDF() method?

If the question is unclear, please let me know.

Put that code in another asp page, and call it from JS with the _blank attribute. — Caveman
The bytes are being returned from a database, the file name is displayed in a gridview. A view button is clicked to display the pdf current process... — Harry
@JimmyChandra how do I set this for every file displayed in a gridview? — Harry

One way is to make view button an anchor and set its attribute to _blank and second is to open file by using code behind.

Call this code on button click

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "a", "window.open('"+strFileId & fileExtension+"','_blank');", true);
