本文实例讲述了asp.net实现批量删除功能的方法。对于asp.net的学习有一定的参考价值。分享给大家供大家参考之用。具体实现方法入戏：
.aspx文件代码如下：
<asp:GridView runat="server" EmptyDataText="暂时无数据" BorderColor="White" OnRowDeleting="GridView1_RowDeleting"> <Columns> <asp:TemplateField HeaderText="选择"> <ItemStyle /> <ItemTemplate> <asp:CheckBox runat="Server" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="id" HeaderText="序号" > <ItemStyle /> </asp:BoundField> <asp:TemplateField HeaderText="标题"> <ItemStyle /> <ItemTemplate> <a href="../shangpu/<%#eval_r("pageurl") %>" target="_blank"><%#eval_r("title") %></a> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="发表时间"> <ItemStyle /> <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 /> </asp:HyperLinkField> <asp:CommandField ShowDeleteButton="True" HeaderText="删除" DeleteText="<div>删除</div>" > <ItemStyle /> </asp:CommandField> </Columns> <EmptyDataTemplate> <font color=red>暂时无数据</font> </EmptyDataTemplate> <RowStyle /> </asp:GridView>
.cs 文件代码如下：
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, "删除成功,共删除" + count + "条记录！"); } } catch { MessageBox.Show(this, "删除失败！"); } finally { con.Close(); con.Dispose(); } }
感兴趣的朋友可以调试运行一下本文实例，学有余力的朋友还可以对代码作出改进以完善其功能。希望本文实例对大家的asp.net学习有一定的帮助作用。
