Hi,
I used this example DEMO, in the ProductDetailsCS.ascx I'd put a button to download a file save in server's folder and save filename on DB, but when click on button show me this error: "Error en tiempo de ejecución de Microsoft JScript: Sys.WebForms.PageRequestManagerParserErrorException: No se pudo analizar el mensaje recibido del servidor. Este error suele producirse cuando la respuesta resulta modificada por llamadas a Response.Write() o cuando los filtros de respuesta, los HttpModules o el seguimiento de servidor están habilitados.
Detalles: Error de análisis cerca de 'PK"

Code Button to Download is

protected void Descargar_Click(object sender, EventArgs e)

{

string filePath = ((Label)FormView1.FindControl("DocumentoConvocatoriaLabel")).Text;

string archivo = "~/DocsGC/"+filePath;

Response.Clear();

Response.ContentType = "application/vnd.ms-excel, application/pdf, application/vnd.ms-excel";

Response.AddHeader("Content-Disposition", "attachment;filename=\"" + archivo + "\"");

Response.Flush();

Response.TransmitFile(Server.MapPath(archivo));

Response.End();

}

Then my FormView on usercontrol:

<asp:FormView ID="FormView1" runat="server" DataKeyNames="IDGC"

Hello Jaime,

The user control loaded in the tooltip is actually loaded in an ASP UpdatePanel. This means you cannot download a file like this from the server cilck handler, because the response from the server is not the full response needed to do this, it is a partial page update.

What I can suggest is executing a JavaScript function that will open the URL you have in a new browser window (or in the same) - see window.open(url) or window.location = url. How to execute a script is explained in this help article - the ScriptManager.RegisterStartupScript() method is perhaps the most robust one.
