1.aspx頁面需要添加：EnableEventValidation="false"
實例：<%@ Page Language="C#" AutoEventWireup="true" EnableEventValidation="false" CodeFile="DefCheckDate.aspx.cs"
Inherits="WebAdmin_CustomRegister_ShortOverFlow_DefCheckDate" %>
2.後台代碼（實例）：
public void btn_ExcelClick(object sender, EventArgs e)
{
if (Gdv_Sof.Rows.Count <= 0)
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script language=‘javascript‘>alert(‘沒有數據！‘)</script>");
return;
}
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=CheckDate.xls");
Response.ContentType="application/excel";
Response.Charset = "Big5";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("Big5");
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
Gdv_Sof.Columns[0].Visible = false;
Gdv_Sof.Columns[1].Visible = false;
Gdv_Sof.HeaderRow.Controls.Clear();
Gdv_Sof.AllowPaging = false;
Gdv_Sof.AllowSorting = false;
BindGridView();
Gdv_Sof.RenderControl(htw);
Response.Write(sw);
Response.End();
Gdv_Sof.AllowPaging = true;
Gdv_Sof.AllowSorting = true;
BindGridView();
}
//此方法一定要有VerifyRenderingInServerForm
public override void VerifyRenderingInServerForm(Control control)
{
}
3.導出的數據格式設置：例如頁面為005，可是導出卻為5，就需要添加以下樣式vnd.ms-excel.numberFormat:@");
實例：
protected void Gdv_Sof_RowDateBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[3].Attributes.Add("style", "vnd.ms-excel.numberFormat:@");
e.Row.Cells[4].Attributes.Add("style", "vnd.ms-excel.numberFormat:@");
}
}
