Asp.net c# ile Gridviewdeki verileri Excel dosyası olarak export etmek

Gridview içerisindeki verileri Excel dosyasına dönüştürmek için gereken classımızı oluşturuyoruz.

Website menüsü-add new item-class

Classımızın adını GridViewExport.cs yapıyoruz.

Classımızın kodları aşağıda…

                control.Controls.Remove(current);

                control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));

            }

            if (current.HasControls())

            {

                GridViewExportUtil.PrepareControlForExport(current);

            }

        }

    }

}

Kaydettikten sonra herhangi bir sayfada ;

GridViewExportUtil.Export("Exceldosyam.xls", GridView1);

Kodunu kullanabiliriz. Bu kod GridView1deki verileri exceldosyam.xls dosyası olarak export etmektedir.

Kolay gelsin.
