本文實(shí)例講述了asp.net實(shí)現(xiàn)批量刪除功能的方法。對(duì)于asp.net的學(xué)習(xí)有一定的參考價(jià)值。分享給大家供大家參考之用。具體實(shí)現(xiàn)方法入戲：
.aspx文件代碼如下：
<asp:GridView ID="GridView1" runat="server" Width="100%" EmptyDataText="暫時(shí)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(hào)" > <ItemStyle Width="20px" /> </asp:BoundField> <asp:TemplateField HeaderText="標(biāo)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(shí)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(shí)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(yùn)行一下本文實(shí)例，學(xué)有余力的朋友還可以對(duì)代碼作出改進(jìn)以完善其功能。希望本文實(shí)例對(duì)大家的asp.net學(xué)習(xí)有一定的幫助作用。
