Opening local file

[Andreas]

Hi All,

with RadWindow I want to open a local PDF file like d://any.pdf

I would be very happy about a hint how to achieve this.

Many thanks

Andi

Hello Andi,

RadWindow works with URLs so you need to use an absolute or relative URL to that file on your server.
e.g.
NavigateUrl = "http://mysite.com/myfolder/myfile.pdf"

Just make sure to set ShowContentDuringLoad to true - this is needed when opening non-web page files like pdf or doc in RadWindow.

Can you give an example of how to open a local file?
I am trying somehting like this and it is not working. This is my code in the OnClientClose of one radwindow where I want to open the file in another rad window. The window opens but it is blank, the file exists but it is not opened in the window. I have ShowContentDuringLoad set to trure for RadWindow2.

In javascript:
var ownd=radopen("file://C:/Users/admin/AppData/Local/Temp/abc.pdf","RadWindow2");
return false;

I have also tried the following, same result, rad window opens but the file does not.
var ownd=radopen("C:/Users/admin/AppData/Local/Temp/abc.pdf","RadWindow2");
return false;

Thanks,
Saritha

RadWindow1.NavigateUrl = "http://99.999.999.999/User/User3/filename.pdf";

RadWindow1.VisibleOnPageLoad = true; //opens the window

Hi Saritha,

 

thats how it works for me.

 

I am setting the url from code behind in c# and also set VisibleOnPageLoad to true, so that once the page is refreshed, the window opens (see above)

On the aspx page I have the following code

<div id="zoneDiv" class="windowTracking">

<telerik:RadWindow ID="RadWindow1" runat="server" Height="500px" Width="500px"
                    CssClass="windowTracking" OffsetElementID="zoneDiv">
 </telerik:RadWindow>

 </div>

 
Formerly, I had the url in the html, but this did not work for me.

Also, on the same aspx page I have

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
    </telerik:RadWindowManager>

Please let me know if this is something which you can use (considering that this code is server side and not client side as you maybe need it.

I am using it from code behind as its easier for me to change the filename and not have it static. So multiple users can use the window at the same time as there are different file names and not just one file which is locked for one user.

Best wishes

Hi Saritha,

RadWindow is based on an IFRAME and it behaves just like that. That is why you cannot open a file by its physical path (actually a physical path has \ as a path separator). In your case you need to use a relative path the same way as you set path to an IFRAME.
For example:

var ownd=radopen("abc.pdf","RadWindow2");

The above code loads a PDF file - abc.pdf, that is located in the root directory of the application, in a new RadWindow.

Thanks Fiko.
So, basically it is easy to load from the server and not so easy to load from the client's machine. I will work around that.

Hi Fiko,

Please, how can I open a file in the server using C# code?

I´m using this approach, without sucess:

protected void RadGrid1_GridExporting(object source, GridExportingArgs e)
    {
        string vnome_arq = "relatorio_" + DateTime.Now.ToString("dd-MM-yy_HH-mm-ss") + "__" + t0302_projeto.SelectedItem.Text.Trim();
        string path = Server.MapPath("~/relatorios/" + vnome_arq + ".pdf");
        using (FileStream fs = File.Create(path))
        {
            Byte[] info = System.Text.Encoding.Default.GetBytes(e.ExportOutput);
            fs.Write(info, 0, info.Length);
        }

        RadWindow1.NavigateUrl = "~/relatorios/" + vnome_arq + ".pdf";
        RadWindow1.ShowContentDuringLoad = true;
        RadWindow1.VisibleOnPageLoad = true;

// THE WINDOW DON´T OPEN      

    }

Thanks, best

Daniel

Hello Daniel,

Assuming that the file is available when you try to access it (i.e. the creation goes well) the RadWindow should be able to load it just like any iframe would.

A possible reason why the RadWindow would not open in this scenario would be if this event is fired in an AJAX request where the RadWindow is not updated in the response. This means that the VisibleOnPageLoad property and the new url will not be sent to the client.

What I can advise is that you inject a JavaScript function instead, for example:

string script = "function f(){radopen(\"" + url + "\", \"RadWindow1\"); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
ScriptManager.RegisterStartupScript(this, this.GetType(), "key", script, true);

More information about this approach is available in this help article.

All the best,

Is it possible to open files present in a client machine rather than from server with telerik controls?

I am trying to open files from (C: drive ) in my local machine on click of File path hyperlink present in a web application.

Hi Dinesh,

If you can set the correct path to a simple <iframe> with JavaScript, the same approach will work with RadWindow too.

Hi Marin,

By Opening I am mean, Launching the local file with the file's respective default program in client machine[quote]

Hello Dinesh,

You can't do that. JavaScript cannot touch the PC, it is sandboxed in the browser, and that's a security feature that cannot be circumvented without things like Flash or Java applets. RadWIndow loads content from the designated URI and that's all it can do for you, it cannot hack the user's PC.
