要全部展示數據，所以導出時要先將翻頁取消，重新綁定數據：gridview的allowpaging屬性設置為false，然后databind()一下
<%@ Page Language="C#" EnableEventValidation = "false" AutoEventWireup="true" CodeFile="SysUser.aspx.cs" Inherits="Autho_SysUser2" %>
添加方法：
public override void VerifyRenderingInServerForm(Control control)
{
}
private void ToExcel(Control ctl, string FileName)
{
HttpContext.Current.Response.Charset = "UTF-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + "" + FileName);
ctl.Page.EnableViewState = false;
System.IO.StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
}
protected void btnCheck0_Click(object sender, EventArgs e)
{
grdlogin.AllowPaging = false;
if (tbxXingming.Text != "")
{
BllImslog bllimslog = new BllImslog();
grdlogin.DataSource = bllimslog.GetRequestLog(tbxXingming.Text, ddlLoginsitu.SelectedValue, tbxStime.Text, tbxEtime.Text);
grdlogin.DataBind();
}
else
{
BindData();
}
ToExcel(this.grdlogin, System.Web.HttpUtility.UrlEncode("IMS登陸情況報表.xls", System.Text.Encoding.UTF8));
}
