添加「導出到Excel」按鈕，網頁導出GridView控件在web應用

我建了一個病人管理軟件的診所所長，我需要出口從ASP.net網格視圖patiet列表，excel文件添加「導出到Excel」按鈕，網頁導出GridView控件在web應用

我的問題是：

是否有出口的GridView到Excel 我使用vb.net和Visual Web Developer 2010

我存儲從高級搜索頁的數據源到一個會話，然後重定向到這裏結果頁面方式是結果代碼頁面

Partial Class Sresults 
Inherits System.Web.UI.Page 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    GridView1.DataSource = Session("dsource") 
    GridView1.DataBind() 

End Sub 

Protected Sub Backbtn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Backbtn.Click 
    Session("dsource") = "" 
    Response.Redirect("searchme.aspx") 

End Sub 

Protected Sub Page_PreRenderComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRenderComplete 
    Response.Write(GridView1.Rows.Count.ToString + " Records") 
End Sub 
End Class

試試下面的按鈕代碼點擊

// Get DataTable that DataGrid is bound to. 
var dataTable = (DataTable)dataGrid.DataSource; 

// Create new ExcelFile. 
var ef = new ExcelFile(); 
// Add new worksheet to the file. 
var ws = ef.Worksheets.Add(dataTable.TableName); 
// Insert the data from DataTable to the worksheet starting at cell "A1". 
ws.InsertDataTable(dataTable, "A1", true); 

// Stream file to browser. 
Response.Clear(); 
Response.ContentType = "application/vnd.ms-excel"; 
Response.AddHeader("Content-Disposition", "attachment; filename=Employee.xls"); 
ef.SaveXls(Response.OutputStream); 
Response.End();

我需要導入微軟互操作的命名空間？我無法在視覺Web開發者快速安裝中找到它！ – 2010-12-09 13:37:37

首先你要下添加到頁面指令來避免運行時錯誤

EnableEventValidation ="false"

添加GridView控件的aspx頁面會話「dsource」正在傳遞包含連接字符串的高級搜索頁面的數據源並選擇命令那麼這裏就是落後

using System; 
using System.Data; 
using System.Configuration; 
using System.Web; 
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using System.Web.UI.WebControls.WebParts; 
using System.Web.UI.HtmlControls; 
using System.Data.SqlClient; 
using System.Threading; 
using System.IO; 
using System.Reflection; 

public partial class csresults : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 

    gridview1.DataSource = Session["dsource"]; 
    gridview1.DataBind(); 




} 


    public override void VerifyRenderingInServerForm(Control control) 
{ 

} 



protected void Button2_Click(object sender, EventArgs e) 
{ 
    HtmlForm form = new HtmlForm(); 
    string attachment = "attachment; filename=Patients.xls"; 
    Response.ClearContent(); 
    Response.AddHeader("content-disposition", attachment); 
    Response.ContentType = "application/ms-excel"; 
    StringWriter stw = new StringWriter(); 
    HtmlTextWriter htextw = new HtmlTextWriter(stw); 
    form.Controls.Add(gridview1); 
    this.Controls.Add(form); 
    form.RenderControl(htextw); 
    Response.Write(stw.ToString()); 
    Response.End(); 
}

代碼}
