The following steps explain the configuration of the Server side events in UploadBox.

In the ASPX page, add the UploadBox element.

  • html
  • <ej:UploadBox ID="Uploadbox" runat="server" SaveUrl="SaveFiles.ashx" RemoveUrl="RemoveFiles.ashx" OnComplete="Uploadbox_Complete" OnErrorFile="Uploadbox_ErrorFile" OnRemoveFile="Uploadbox_RemoveFile"></ej:UploadBox>

    NOTE

    The SaveUrl and RemoveUrl are the same as above (see Save File Action and Remove File Action section).

    Define the corresponding server side handlers in code behind

  • c#
  • protected void Uploadbox_Complete(object sender, Syncfusion.JavaScript.Web.UploadBoxCompleteEventArgs e)
    
    {
    
        //e.Size - Gets the file size

        //e.EventType - Returns the event name
    
        //e.FileStatus - Gets the dictionary value of Size, Name, Extension and RawFile
    
    }
    
    protected void Uploadbox_ErrorFile(object sender, Syncfusion.JavaScript.Web.UploadBoxErrorFileEventArgs e)
