GridView常用操作事件图文介绍

对于gridview学NET的同学再熟悉不过，但是其中功能事件是否能编码熟练实现？前不久看点博文，以及资料，综合自己的一些想法，汇总如下：

数据库设计如下，以便更好理解：

设计：

实现：

GridView无代码分页排序

小实例：

AllowSorting设为True，aspx代码中是AllowSorting="True"；

运行结果：

GridView选中，编辑，取消，删除

小实例：

GridView.aspx

复制代码代码如下:

 
asp:GridView ID="GridView1" runat="server" Height="138px" Width="1117px" 
AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" 
onpageindexchanging="GridView1_PageIndexChanging" 
onrowcancelingedit="GridView1_RowCancelingEdit" 
onrowdeleting="GridView1_RowDeleting" onrowediting="GridView1_RowEditing" 
onrowupdating="GridView1_RowUpdating"> 
Columns> 

asp:TemplateField HeaderText="身份证号" SortExpression="pid"> 
ItemTemplate> 
asp:Label ID="Label1" runat="server" Text='%# Bind("pid") %>'>/asp:Label> 
/ItemTemplate> 
/asp:TemplateField> 
%-- asp:BoundField DataField="pid" HeaderText="身份证号" SortExpression="pid" />--%> 
asp:BoundField DataField="pname" HeaderText="姓名" SortExpression="pname" /> 
asp:BoundField DataField="psex" HeaderText="性别" SortExpression="psex" /> 
asp:BoundField DataField="padress" HeaderText="地址" SortExpression="padress" /> 
asp:BoundField DataField="pyoubiao" HeaderText="邮编" SortExpression="pyoubiao" /> 
asp:BoundField DataField="pprice" HeaderText="工资起价" SortExpression="pprice" /> 
asp:CommandField HeaderText="选择" ShowSelectButton="True" /> 
asp:CommandField HeaderText="编辑" ShowEditButton="True" /> 
asp:CommandField HeaderText="删除" ShowDeleteButton="True" /> 
/Columns> 
EmptyDataRowStyle BackColor="Red" /> 
HeaderStyle BackColor="#0000CC" Font-Bold="True" ForeColor="White" /> 
PagerStyle BackColor="#864" HorizontalAlign="Center" ForeColor="White"/> 
/asp:GridView> 

GridView.aspx.cs

复制代码代码如下:

 
//公有数据 
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlcon"].ConnectionString); 
SqlCommand cmd; 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
{ 
bind(); //正常绑定 
} 
}

public void bind() 
{ 
//数据连接web.config中已配置的数据 
SqlDataAdapter da = new SqlDataAdapter("select top 5 * from person", con);//使用数据适配器内置查询，自动开闭数据库 
DataSet ds = new DataSet();//使用数据集，采取断开式访问数据 
da.Fill(ds, "person"); 
GridView1.DataSource = ds; 
GridView1.DataKeyNames=new string[]{"pid"};//设置主键 
GridView1.DataBind(); 
} 

//实现分页 
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
GridView1.PageIndex = e.NewPageIndex; 
this.bind(); 
} 
//删除 
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) 
{ 
string sqlstr = "delete from person where pid='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'"; 
con.Open(); 
cmd = new SqlCommand(sqlstr, con); 
cmd.ExecuteNonQuery(); 
con.Close(); 
bind(); 


} 
//取消编辑 
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) 
{ 
GridView1.EditIndex = -1; 
bind(); 
} 
//编辑 
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) 
{ 
GridView1.EditIndex = e.NewEditIndex; 
bind(); 
} 

//更新 
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) 
{ 
string sqlstr = "update person set pname='" 
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',psex='" 
+((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim()+"',padress='"

cmd = new SqlCommand(sqlstr, con); 
con.Open(); 
cmd.ExecuteNonQuery(); 
con.Close(); 
GridView1.EditIndex = -1; 
bind(); 

} 

运行结果：

GridView正反双向排序
