Hi, <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I have used fusion charts in my web application with drilldown option using javascript & Ajax within a single page. When I click on graph loaded, ajax page will be called and the generated graph is placed in another div tag. Similarly, I have generated 4 graphs in a page on click the graph. I have used session for user identification. After Session get expired, when I click on second graph loaded using ajax how can I redirect to login page.(This is my first issue.) Also I used one linkbutton for exporting excel file. After clicking this linkbutton if I click on graph for further drilldown, it shows error message since I have used resonse.End() method for downloading excel report. Could u please tell me some solutions (or) some other logic for implementing this.

Hi, As described in above mentioned link,if i use j-format instead of javascript in link property of <set> tag, then also i will get the same problem. Since i have used response.End() method for export to excel, page get refreshed.So only one graph will be displayed.Drilldown graphs will not be generated since these graphs r generated using ajax on click on the graph.

Hi Srividya, How to use j- format in fusionchart for drilldown

Hi Srividhya, thanks a lot for your timing & useful reply.

This code is used for excel export on button click,GridView dg = new GridView(); dg.HorizontalAlign = HorizontalAlign.Center; dg.AutoGenerateColumns = true; dg.CssClass = "Tableheadertext"; dg.CellPadding = 10; dg.HeaderStyle.BackColor = System.Drawing.Color.FromName("#7AABD9"); dg.HeaderStyle.HorizontalAlign = HorizontalAlign.Center; dg.HeaderStyle.CssClass = "Tableheadertext"; dg.AlternatingRowStyle.BackColor = System.Drawing.Color.FromName("#EFF3FB"); dg.RowCreated += new System.Web.UI.WebControls.GridViewRowEventHandler(GridView_Merge_Inference_Header_RowCreated); dg.RowCreated += new System.Web.UI.WebControls.GridViewRowEventHandler(GridView_Merge_BlankHeader_RowCreated); dg.DataSource = ds.Tables[0]; dg.DataBind(); dg.RenderControl(htw); HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Charset = ""; response.ContentType = "application/vnd.ms-excel"; response.AddHeader("Content-Disposition", "attachment;filename="" + filename + """); response.Write(sw.ToString()); response.End(); After clicking this button,if i click on the graph for drilldown it ask for page refresh. if i refresh the page all the drilldown graphs disappear, since the graphs r generated using ajax page.
