I am using the example DBContentProvider-Vb.
How do i disable RadWindow to open when i want to download  a images, pdf, ecxel and other files?
I only want to have the download dialog....

Hi Kjell,

To download files instead of open them you need to pass the files as an attachment through the content provider's handler. Please review the following live demo demonstrating such implementation:

It works for all file extensions in addition to pictures. This will open the image in the browser. I want to get the dialog to download the image. See attached Open.png that I get with other file extensions.
Open.png

var requestImage = "Handler.ashx?path=" + item.get_url(); does not work, get double Handler.ashx? path ....
this works: var requestImage = item.get_url();

function OnClientFileOpen(oExplorer, args) {
    var item = args.get_item();
    var fileExtension = item.get_extension();

    if (fileExtension == "jpg" || fileExtension == "gif" || fileExtension == "png" || fileExtension == "pdf") {
        args.set_cancel(true);

        // var requestImage = "Handler.ashx?path=" + item.get_url(); This not work.....
        var requestImage = item.get_url();
        document.location = requestImage;
    }
}

Hi Kjell,

FileExplorer is already using a generic handler when working with a DB provider, this is why it is enough to request directly the item by its url. The other thing you have to do is to implement the download logic from the handler from the demo to the one used in your application.

Commenting the following if statement in the Handler.ashx file will allow you to download all type of files:

private void WriteFile(byte[] content, string fileName, string contentType, HttpResponse response)
{
    response.Buffer = true;
    response.Clear();
    response.ContentType = contentType;
    string extension = System.IO.Path.GetExtension(fileName).ToLower();
    //if (extension != ".htm" && extension != ".html" && extension != ".xml" && extension != ".jpg" && extension != ".gif" && extension != ".png")
    //{
        response.AddHeader("content-disposition", "attachment; filename=" + fileName);

    //}
    response.BinaryWrite(content);
    response.Flush();
    response.End();
}

I hope this helps.
