I am trying to export data to Excel. And I have GridView with paging enabled. When I download data using HtmlTextWriter it give download only to visible record in GridView. Can we download all the record in single excel file? And also downloaded-data should be with the same sorted state as sorted in GridView?
Client Source code
<asp:GridView ID="gvDetailFleet" runat="server" DataSourceID="SqlDataSource2"
AllowPaging="false" AllowSorting="True" AutoGenerateColumns="true"
DataKeyNames="OracleId" CellPadding="4" ForeColor="#333333"
GridLines="None" >
<RowStyle BackColor="#EFF3FB" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<EditRowStyle BackColor="#2461BF" />
<AlternatingRowStyle BackColor="White" />
</asp:GridView>

You may try to do like this
GridView gv = new GridView();
gv.DataSource = sourceList; //Your datasource from database
gv.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=Preferred_Funds-" + DateTime.Now.ToShortDateString() + ".xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
//try this code inside the button
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=ExportData1.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.xls";
StringWriter StringWriter = new System.IO.StringWriter();
HtmlTextWriter HtmlTextWriter = new HtmlTextWriter(StringWriter);
//batigol
GridView1.AllowPaging = false;
GridView1.DataSource = Session["uu"];
GridView1.DataBind();
//
GridView1.RenderControl(HtmlTextWriter);
Response.Write(StringWriter.ToString());
Response.End();
