    Hi,

     Am using rad chart.i want to export my image in local system.

    Am using following code


               
                    System.IO.MemoryStream ms1 = new System.IO.MemoryStream();
                    this.chartPie.Save(ms1, System.Drawing.Imaging.ImageFormat.Png);
                    this.Page.Response.Clear();
                    this.Page.Response.ClearHeaders();
                    this.Page.Response.AddHeader("Content-disposition", "attachment; filename=PieChart.png");
                    this.Page.Response.AddHeader("Content-type", "image/png");
                    this.Page.Response.BinaryWrite(ms1.ToArray());
                    this.Page.Response.End();
              
        

    The chart is getting saved while running in local.while running my project through IIS, i am getting "object reference error".
    I gave all permissions to folders and also IIS.Even setting all permissions, i am getting the same error.

    Thanks for any help,

    Hi sabarishbabu,

    Unfortunately we are unable to reproduce the problematic behavior in our local tests with IIS so we are unsure that the problem you are experiencing is related to the control. Please review the attached sample application and let us know how can we observe the issue locally.
