        Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "filename.xls"));
        Response.ContentType = "application/ms-excel";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw); 
        base.OnPreRender(e);
        ScriptManager sm = ScriptManager.GetCurrent(Page);
        sm.RegisterScriptControl(LineChart1);
        LineChart1.Visible = true;          
       for (int i = 0; i < grdview1.HeaderRow.Cells.Count; i++)
        {
           grdview1.HeaderRow.Cells[i];
        }
        grdview1.RenderControl(htw);
        LineChart1.RenderControl(htw);
        Response.Write(sw.ToString());
        Response.End();        
    }

public override void VerifyRenderingInServerForm(Control control)
    {
        /* Verifies that the control is rendered */
    }

I added OnPreRender() for Registering the scriptmanager control

    protected override void OnPreRender(EventArgs e)
    {
        /* Verifies that the control is rendered */
        base.OnPreRender(e);
        ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);

        if (scriptManager == null)
        {

            scriptManager = new ScriptManager();

            scriptManager.ID = "ScriptManager1";

            scriptManager.EnablePartialRendering = true;

            Controls.AddAt(0, scriptManager);

        }
    }

Can anyone help me out how can i export linechart.

Thank you
