1.GridView无代码分页排序:
效果图:
小提示:
1.AllowSorting设为True,aspx代码中是AllowSorting="True";
2.默认1页10条,如果要修改每页条数,修改PageSize即可,在aspx代码中是PageSize="12"。
3.默认的是单向排序的,右击GridView弹出“属性”,选择AllowSorting为True即可。
2.GridView选中,编辑,取消,删除:
效果图:
后台代码:
你可以使用sqlhelper,本文没用。代码如下:
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; public partial class _Default : System.Web.UI.Page { SqlConnection sqlcon; SqlCommand sqlcom; string strCon = "Data Source=(local);Database=数据库名;Uid=帐号;Pwd=密码"; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { bind(); } } protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { GridView1.EditIndex = e.NewEditIndex; bind(); } //删除 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { string sqlstr = "delete from 表 where"; sqlcon = new SqlConnection(strCon); sqlcom = new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); bind(); } //更新 protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { sqlcon = new SqlConnection(strCon); string sqlstr = "update 表 set 字段1='" + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',字段2='" + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "',字段3='" + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "' where"; sqlcom=new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); GridView1.EditIndex = -1; bind(); } //取消 protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { GridView1.EditIndex = -1; bind(); } //绑定 public void bind() { string sqlstr = "select * from 表"; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, "表"); GridView1.DataSource = myds; GridView1.DataKeyNames = new string[] { "id" };//主键 GridView1.DataBind(); sqlcon.Close(); } }
前台主要代码:
... ... <asp:GridView runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit"> <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> <Columns> <asp:BoundField DataField="身份证号码" HeaderText="用户ID" ReadOnly="True" /> <asp:BoundField DataField="姓名" HeaderText="用户姓名" /> <asp:BoundField DataField="员工性别" HeaderText="性别" /> <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" /> <asp:CommandField HeaderText="选择" ShowSelectButton="True" /> <asp:CommandField HeaderText="编辑" ShowEditButton="True" /> <asp:CommandField HeaderText="删除" ShowDeleteButton="True" /> </Columns> <RowStyle ForeColor="#000066" /> <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" /> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> </asp:GridView>
3.GridView正反双向排序:
效果图:点姓名各2次的排序,点其他也一样可以。
后台代码:
using System; using System.Data; using System.Configuration; using System.Collections; 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; public partial class Default3 : System.Web.UI.Page { SqlConnection sqlcon; string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd="; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { ViewState["SortOrder"] = "身份证号码"; ViewState["OrderDire"] = "ASC"; bind(); } } protected void GridView1_Sorting(object sender, GridViewSortEventArgs e) { string sPage = e.SortExpression; if (ViewState["SortOrder"].ToString() == sPage) { if (ViewState["OrderDire"].ToString() == "Desc") ViewState["OrderDire"] = "ASC"; else ViewState["OrderDire"] = "Desc"; } else { ViewState["SortOrder"] = e.SortExpression; } bind(); } public void bind() { string sqlstr = "select top 5 * from 飞狐工作室"; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, "飞狐工作室"); DataView view = myds.Tables["飞狐工作室"].DefaultView; string sort = (string)ViewState["SortOrder"] + " " + (string)ViewState["OrderDire"]; view.Sort = sort; GridView1.DataSource = view; GridView1.DataBind(); sqlcon.Close(); } }
