本文實例講述了asp.net實現(xiàn)批量刪除功能的方法。對于asp.net的學習有一定的參考價值。之用。具體實現(xiàn)方法入戲：

.aspx文件代碼如下：

<asp:GridView ID="GridView1" runat="server" Width="100%" EmptyDataText="暫時無數(shù)據(jù)" BorderColor="White" OnRowDeleting="GridView1_RowDeleting"><Columns><asp:TemplateField HeaderText="選擇"><ItemStyle Width="20px" />    <ItemTemplate>      <asp:CheckBox id="id" runat="Server" />    </ItemTemplate>  </asp:TemplateField>   <asp:BoundField DataField="id" HeaderText="序號" > <ItemStyle Width="20px" />   </asp:BoundField>   <asp:TemplateField HeaderText="標題"> <ItemStyle Width="400px" /> <ItemTemplate>   <a href="../shangpu/<%#eval_r("pageurl") %>" target="_blank"><%#eval_r("title") %></a> </ItemTemplate>   </asp:TemplateField>   <asp:TemplateField HeaderText="發(fā)表時間"> <ItemStyle Width="100px" /> <ItemTemplate>   <%# Convert.ToDateTime(eval_r("addtime")).Date.ToString("yyyy-MM-dd") %> </ItemTemplate>   </asp:TemplateField>   <asp:HyperLinkField DataNavigateUrlFormatString="shangpu_edit.aspx?id={0}" Text="修改" NavigateUrl="shangpu_edit.aspx?id={0}" DataNavigateUrlFields="id" > <ItemStyle Width="30px" />   </asp:HyperLinkField>    <asp:CommandField ShowDeleteButton="True" HeaderText="刪除" DeleteText="<div id="de" onclick="JavaScript:return confirm('確定刪除嗎？')">刪除</div>" > <ItemStyle Width="30px" />   </asp:CommandField> </Columns> <EmptyDataTemplate> <font color=red>暫時無數(shù)據(jù)</font> </EmptyDataTemplate><RowStyle Height="20px" />  </asp:GridView> 

.cs 文件代碼如下：

protected void btndeleteall_Click(object sender, EventArgs e){string sqltext = "(";for (int i = 0; i < GridView1.Rows.Count; i++){  CheckBox chb = (CheckBox)GridView1.Rows[i].FindControl("id");  if (chb.Checked)  { sqltext = sqltext + GridView1.DataKeys[i].Value.ToString() + ",";  }}sqltext = sqltext.Substring(0, sqltext.Length - 1) + ")";sqltext = "delete from shangpu where id in" + sqltext;string sqlcon = ConfigurationManager.AppSettings["ConnectionString"].ToString();SqlConnection con = new SqlConnection(sqlcon);con.Open();SqlCommand cmd = new SqlCommand(sqltext, con);try{  int count = Convert.ToInt32(cmd.ExecuteNonQuery());  if (count > 0)  { viewbind(); MessageBox.Show(this, "刪除成功,共刪除" + count + "條記錄！");  }}catch{  MessageBox.Show(this, "刪除失敗！");}finally{  con.Close();  con.Dispose();}}

感興趣的朋友可以調(diào)試運行一下本文實例，學有余力的朋友還可以對代碼作出改進以完善其功能。希望本文實例對大家的asp.net學習有一定的幫助作用。
