You can display the pdf, jpg etc in an iframe on the same page or another. For eg:

<iframe id="iframe" runat="server" src="NameOfYourFolder/pdf.pdf"></iframe>

Here i have hardcoded the path to the pdf file which will be displayed within the iframe. You need to create a mechanism to get the path of the file associated with that linkbutton in the GridView and pass that path to iframe's src through embedded code blocks.

First Way to show PDF in browser

protected void btnOpen_Click(object sender, EventArgs e)
{
Response.Redirect("SiteAnalytics.pdf");
}

Second way to Show PDF in browser by setting Content Type of the Response object and add the binary form of the pdf in the header

protected void btnpdf_Click(object sender, EventArgs e)
{
string path = Server.MapPath("SiteAnalytics.pdf");
WebClient client = new WebClient();
Byte[] buffer = client.DownloadData(path);

if (buffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", buffer.Length.ToString());
Response.BinaryWrite(buffer);
}

You should specify Content-Disposition: inline header. If the browser will support the display of the type you specified in Content-Type header, it will be displayed in the browser.

The opposite is Content-Disposition: attachment which will force the browser to provide Save As button for your content (even when it is HTML).

This depends on the file type and how the current system is configured to handle that type.

For instance, most images will just open in a browser by default; however, for me, I have Chrome configured as the default registered application for PDF files, yet this is hardly a standard thing right now, many many general users will have just what they were told to download when installing something else, something awful like Foxit reader - and in such cases, where the browser isn't registered to handle the file type, it won't happen.
