AsyncUpload files format being changed

[Joshua]

Hello

I am using AsyncUpload to upload photos and store them in a folder that exists inside my project

        <asp:Label ID="PhotoLabel" runat="server" Text="Upload a photo"></asp:Label>
        <telerik:RadAsyncUpload RenderMode="Lightweight" runat="server" ManualUpload="false"  ID="AsyncUpload1" MultipleFileSelection="Disabled" OnFileUploaded="AsyncUpload1_FileUploaded"></telerik:RadAsyncUpload>
        <telerik:RadButton runat="server" Text="Sibmit new photos" OnClick="UploadFiles_Click"></telerik:RadButton>
        <asp:Label ID="error" runat="server" Text="" Visible="false"></asp:Label>

 

    protected void UploadFiles_Click(object sender, EventArgs e)
    {
        try
        {
            if(AsyncUpload1.UploadedFiles.Count > 0)
            {
                foreach (UploadedFile file in AsyncUpload1.UploadedFiles)
                {
                    string targetFolder = HttpContext.Current.Server.MapPath("~/images");
                    string targetPath = Path.Combine(targetFolder, file.ToString());

                    file.SaveAs(targetPath);    
                }
                error.Text = "File Uploaded";
                error.Visible = true;

            }
            else
            {
                error.Text = "no files to upload";
                error.Visible = true;
                return;
            }
        }
        catch(Exception ex)
        {
            error.Text = ex.ToString();
            error.Visible = true;
        }
    }

 

This code works. And stores a file on the correct folder. The problem is that instead of it being a png like I uploaded its a 'Telerik.Web.UI.AsyncUploadedFile'

Hello Joshua,

In order to save the file and keep its name and extension you will have to change the following line in the UploadFiles_Click() handler:

string targetPath = Path.Combine(targetFolder, file.ToString());

to:

string targetPath = Path.Combine(targetFolder, file.FileName);

More information on how the files can be manipulated on the server side is available in the following article.
