I have this code below which takes my GridView, populates it, and generates and opens an Excel file with the griddata in my browser.
What if I want to save that file directly to my server or attach it to an email message, instead of the display prompt that automatically pops up.
Can I do that with small modifications to the script?
protected void btnExcelExport_Click(object sender, EventArgs e)
{
HtmlForm form = new HtmlForm();
Response.Clear();
Response.Buffer = true;
Response.Charset = "";
Response.AddHeader("content-disposition", string.Format("attachment;filename={0}", "Student.xls"));
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
BindGridDetails(GridView1);
form.Attributes["runat"] = "server";
form.Controls.Add(GridView1);
this.Controls.Add(form);
form.RenderControl(hw);
string style = #"<!--mce:2-->";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
you can save your grid data as a Comma Separated Value file on the server and email or save it directly on your server.
CSV files can be opened using Excel.

Title may not describing well what I'm asking for,
Actually I'm looking for some guidelines to solve my code issue,
I'm creating a application that will export the HTML page with data in
Grid view and logo images to excel. What I've done so far in below:
private void ExportExcel()
{
//This method is defined in ButtonClick Event
Response.Clear();
Response.Buffer = true;
Response.ClearContent();
Response.ClearHeaders();
Response.Charset = "";
GridView2.AllowPaging = false;
string FileName = "Exported" + DateTime.Now + ".xls";
StringWriter strwritter = new StringWriter();
HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);
this.EnableViewState = false;
GridView2.DataBind();
Response.Write(ExportDiv.InnerHtml);
GridView2.GridLines = System.Web.UI.WebControls.GridLines.Both;
GridView2.HeaderStyle.Font.Bold = true;
GridView2.RenderControl(htmltextwrtter);
Response.Write(strwritter.ToString());
Response.End();
}
This above code is working fine, but they issue is with the logo image Attach images shows issue with logo image,
Check Image here
The logo image is not set inside a cell what i actually need. What i
need is shown in this pic Please check image
Without using any outsource library you can do this, Things that was causing issue the alignment of the Grid view and HTML code.
So what I've done is create a div and named it ExportDiv and add
HTML Table inside ExportDiv, after that I write my HTML code inside
table by adding row and columns again and again, and add grid view
inside my Table which was created inside ExportDiv.
Following is the code that works behind the click event.
private void ExportToExcel(string strFileName)
{
StringBuilder sb = new StringBuilder();
string attachment = "attachment; filename=" + strFileName;
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/vnd.ms-excel";
Response.Clear();
Response.Buffer = true;
Response.Charset = "";
StringWriter oStringWriter = new StringWriter();
HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);
Response.Output.Write(sb.ToString());
GridView3.AllowPaging = false;
GridView3.DataBind();
ExportDiv.RenderControl(oHtmlTextWriter);
string style = #"<style> TD { mso-number-format:\#; } </style>";
Response.Output.Write(oStringWriter.ToString());
Response.Write(style);
Response.End();
}
The good thing about the above code is it set HTML design and Grid view alignment accordingly.
Anyone else facing issue in this type of work can ask in comments
