 <ext:CommandColumn ID="CommandColumn1" runat="server" Width="60" >
                        <PrepareToolbar Fn="prepareToolbar" />
                          <Commands>
                               <ext:GridCommand Icon="Page" CommandName="View">
                                           <ToolTip Text="Посмотреть" />
                                </ext:GridCommand>
                            </Commands>
                       
                       <DirectEvents>
                           <Command OnEvent="ShowDoc"  Success="onAfterShowDoc"  IsUpload="true" >
                              <%--  <EventMask ShowMask="true"  />--%> 
                                        <ExtraParams>
                                            <ext:Parameter Name="ext" Value=record.data.col6 Mode="Raw" />   
                                            <ext:Parameter Name="link" Value=record.data.col1 Mode="Raw" />
                                        </ExtraParams>

                           </Command>
                       </DirectEvents>

on the server side i found 2 examples..
this work for me.. but open dialog - where i must select open or save..

  protected void ShowDoc(object sender, DirectEventArgs e)
    {

        string ext = e.ExtraParams["ext"];
        string link = e.ExtraParams["link"];
   
     FileInfo file = new FileInfo(link);
        // Checking if file exists
        if (file.Exists)
        {
            Response.ClearContent();
            Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
            Response.AddHeader("Content-Length", file.Length.ToString());
            if (ext == "pdf")
                Response.ContentType = "application/pdf";
            else
                Response.ContentType = "application/html";  
            Response.TransmitFile(file.FullName);
            Response.End();
        }
    }

and two examples - open content in window ( the same what i want)

  protected void ShowDoc(object sender, DirectEventArgs e)
    {

        string ext = e.ExtraParams["ext"];
    
        string link = e.ExtraParams["link"];
 

           var win = new Ext.Net.Window()
            {
                ID = "newDocument",
                Title =ext,
                Width = Unit.Pixel(1000),
                Height = Unit.Pixel(600),
                Modal = true,
                Collapsible = false,
                Maximizable = true,
 
                BodyStyle = "padding:10px;",
                AnimateTarget = sender.ToString(),
                Icon = Icon.PageWhiteAcrobat,
                Loader = new ComponentLoader
                {
                    Url = link, // this link only internal for IIS.??. i want  open from net share path.. html and pdf file
                    Mode = LoadMode.Frame,
                    LoadMask = { ShowMask = true },
                    MonitorComplete=true
                }
      
         };
           win.Render(this.Form1);
       }
