uvavilala,

 

Try

 

protected void edtContent_PostBackCommand(object sender, CommandEventArgs e)
    {
      
        if (string.Compare(e.CommandName, "Save", true) == 0)
        {
            try
            {
            //    this.edtContent.SaveFile(loadfilepath);
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
    }

 

And try again.

 

Keep me posted
