How to force browser to download, not view, PDF documents in ASP.NET Webforms
asp.net, html, webforms
Solution
Use a linkbutton so you can run serverside code on click:
<asp:LinkButton ID="hl_download" runat="server" OnClick="hl_download_Click">Download</asp:LinkButton>
Then, in the codebehind:
public void hl_download_Click(Object sender, EventArgs e)
{
Response.AddHeader("Content-Type", "application/octet-stream");
Response.AddHeader("Content-Transfer-Encoding","Binary");
Response.AddHeader("Content-disposition", "attachment; filename=\"IdeaPark_ER_diagram.pdf\"");
Response.WriteFile(HttpRuntime.AppDomainAppPath + @"ideaPark\DesktopModules\ResourceModule\pdf_resources\IdeaPark_ER_diagram.pdf");
Response.End();
}
This assumes that the web path maps cleanly to the filesystem path of the file. Otherwise modify `Response.WriteFile()` so that it points to the location of the pdf file on the filesystem.
Problem
just want to ask how can I prevent the web Browser from View on Browser because every time user click the link to download it View in Browser ``` asp.net controller <li><asp:HyperLink ID="hl_download" runat="server" >Download</asp:HyperLink></li> html <a id="dnn_ctr932_View_hl_download" href="/ideaPark/DesktopModules/ResourceModule/pdf_resources/IdeaPark_ER_diagram.pdf">Download</a> ```
