Export data to Excel file with ASP.NET MVC 4 C# is rendering into view
asp.net-mvc, export-to-excel
Solution
I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):
public ActionResult ExportToExcel()
{
var products = new System.Data.DataTable("teste");
products.Columns.Add("col1", typeof(int));
products.Columns.Add("col2", typeof(string));
products.Rows.Add(1, "product 1");
products.Rows.Add(2, "product 2");
products.Rows.Add(3, "product 3");
products.Rows.Add(4, "product 4");
products.Rows.Add(5, "product 5");
products.Rows.Add(6, "product 6");
products.Rows.Add(7, "product 7");
var grid = new GridView();
grid.DataSource = products;
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
Problem
I am having trouble exporting data to Excel. The following seems to render the gridview into my View, instead of prompting the user to open with Excel, which I have installed on my machine. ``` Public ActionResult ExportToExcel() { var products = this.Repository.Products.ToList(); var grid = new GridView(); grid.DataSource = from p in products select new { Id = p.Id, Name = p.Name }; grid.DataBind(); Response.ClearContent(); Response.Buffer = true; Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls"); Response.ContentType = "application/ms-excel"; Response.Charset = ""; StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); grid.RenderControl(htw); Response.Output.Write(sw.ToString()); Response.Flush(); Response.End(); return View("MyView"); } ``` What am I doing wrong?
