GridView读取Excel数据

private DataSet CreateDataSource()

{

string strCon;

strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";

OleDbConnection olecon = new OleDbConnection(strCon);

OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);

DataSet myds = new DataSet();

myda.Fill(myds);

return myds;

}

protected void Button1_Click(object sender, EventArgs e)

{

GridView1.DataSource = CreateDataSource();

GridView1.DataBind();

}

如果GridView存在模板列，其中包含子控件，例如CheckBox等，导出EXCEL后就会出现该区域的不规律。所以要对模板列单独处理（转载）

public static void PrepareGridViewForExport(Control gv)//模式化特殊元素 flashcong

{

LinkButton lb = new LinkButton();

Literal l = new Literal();

string name = String.Empty;

for (int i = 0; i < gv.Controls.Count; i++)

{

if (gv.Controls[i].GetType() == typeof(LinkButton))

{

l.Text = (gv.Controls[i] as LinkButton).Text;

gv.Controls.Remove(gv.Controls[i]);

gv.Controls.AddAt(i, l);

}

else if (gv.Controls[i].GetType() == typeof(DropDownList))

{

l.Text = (gv.Controls[i] as DropDownList).SelectedItem.Text;

gv.Controls.Remove(gv.Controls[i]);

gv.Controls.AddAt(i, l);

}

else if (gv.Controls[i].GetType() == typeof(CheckBox))

{

l.Text = (gv.Controls[i] as CheckBox).Checked ? "True" : "False";

gv.Controls.Remove(gv.Controls[i]);

gv.Controls.AddAt(i, l);

}

else if (gv.Controls[i].GetType() == typeof(ImageButton))

{

l.Text = "图片";

gv.Controls.Remove(gv.Controls[i]);

gv.Controls.AddAt(i, l);

}

if (gv.Controls[i].HasControls())

{

PrepareGridViewForExport(gv.Controls[i]);

}

}

}
