Unable get the File names in RadUpload in codebehind (C#)

[Mohan]

Hi ,
         I am unable to get the file names in the RadUpload  control .

IN ASPX

   <telerik:RadUpload runat="server" id="RadUpload1" />

IN ASPX.CS

    protected void SaveChanges_Click(object sender, EventArgs e)
        {
            int count = RadUpload1.UploadedFiles.Count;                    
        }

Error :  Unable to get the Uploaded files count in Server side.

Note :  I have tried the following work arounds in below, still i didn't get the output, This control is placed under Nested Master page -> inside RadMultiPage -> RadPanelItem -> RadUpload1

http://www.telerik.com/help/aspnet-ajax/upload-uploading-ajax.html

Please check the attached sample file

Regards

Hi,

By default files could not be uploaded with Ajax when using the RadUpload control. Here is a help article on the matter.

Kind regards,

Hi Dimitar ,
         Thanks for your reply . But I have already tried this link and also i have mentioned that same link  what you have send  .
So can you give me some good solutions :)  for Radupload or .net file upload  to solve this issues

for your easy understanding  I have made a sample  for you.

 

In Master page  Please add the below line
====================
   <telerik:RadScriptManager ID="RadScriptManager1" runat="server" AsyncPostBackTimeout="41600"  />
=====================
Default.aspx.cs

        protected void Button1_Click(object sender, EventArgs e)
        {  string strUpload=Upload.FileName ;// File Name is Empty here .Please help me out 
            if (RadUpload.UploadedFiles.Count > 0)            {
                string str = RadUpload.UploadedFiles[0].FileName;
            }
        }
Default.aspx

Hi,

In such scenario where Ajax is being used it's convenient to use the RadAsyncUpload control instead. Here is a link to its documentation and here is a link to the online demos.
