推荐答案
研究这个例子并适应你的需要：
aspx页面：
Study this example and adapt to your need:
the aspx page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default31.aspx.cs" Inherits="Default31" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</form>
</body>
</html>
背后的代码：
the code behind:
using System;
using System.Web.UI.WebControls;
using System.Data;
public partial class Default31 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack == true)
return;
DataTable dtTemp = new DataTable();
dtTemp.Columns.Add("Student ID");
dtTemp.Columns.Add("First Name");
dtTemp.Columns.Add("Last Name");
dtTemp.Rows.Add("1", "Peter", "Leow");
dtTemp.Rows.Add("2", "James", "Song");
dtTemp.Rows.Add("3", "Mick", "Sam");
dtTemp.Rows.Add("4", "MAry", "Cool");
GridView1.DataSource = dtTemp;
GridView1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox chkBox = (CheckBox)row.FindControl("CheckBox1");
if (chkBox != null && chkBox.Checked)
{
TextBox1.Text = row.Cells[2].Text.ToString();
}
}
}
}
在Gridview中添加复选框
这是asp.net项目的格式并拖动gridview控件
Add Checkbox in Gridview
Here is the format for asp.net project and drag the gridview control
<asp:gridview id="GridVwHeaderChckbox" runat="server" autogeneratecolumns="False" xmlns:asp="#unknown">
Font-Names="Verdana" PageSize="5" Width="55%" BorderColor="#CCCCCC" BorderStyle="Solid"
BorderWidth="1px">
<alternatingrowstyle backcolor="#BFE4FF" />
<pagerstyle bordercolor="#CCCCCC" borderstyle="Solid" borderwidth="1px" />
<headerstyle height="30px" backcolor="#6DC2FF" font-size="15px" bordercolor="#CCCCCC">
BorderStyle="Solid" BorderWidth="1px" />
<rowstyle height="20px" font-size="13px" bordercolor="#CCCCCC" borderstyle="Solid">
BorderWidth="1px" />
<columns>
<asp:boundfield datafield="Emp_Name" headertext="Employee Name" headerstyle-width="150px" />
<asp:boundfield datafield="Emp_job" headertext="Job title" headerstyle-width="150px" />
<asp:boundfield datafield="Emp_Dep" headertext="Department" headerstyle-width="150px" />
<asp:templatefield itemstyle-width="40px">
<headertemplate>
<asp:checkbox id="chkboxSelectAll" runat="server" onclick="CheckAllEmp(this);" />
</headertemplate>
<itemstyle horizontalalign="Center" verticalalign="Middle" />
<itemtemplate>
<asp:checkbox id="chkEmp" runat="server"></asp:checkbox>
</itemtemplate>
</asp:templatefield>
</columns>
</rowstyle></headerstyle></asp:gridview> < br $>
选择并取消选中复选框
Select and deselect checkbox
<asp:templatefield itemstyle-width="40px" xmlns:asp="#unknown">
<headertemplate>
<asp:checkbox id="chkboxSelectAll" runat="server" autopostback="true" oncheckedchanged="chkboxSelectAll_CheckedChanged" />
</headertemplate>
<itemstyle horizontalalign="Center" verticalalign="Middle" />
<itemtemplate>
<asp:checkbox id="chkEmp" runat="server"></asp:checkbox>
</itemtemplate>
</asp:templatefield>
将autopostback设置为true并在复选框中创建OnCheckedChanged事件
set autopostback as true and create OnCheckedChanged event in checkbox
protected void chkboxSelectAll_CheckedChanged(object sender, EventArgs e)
{
CheckBox ChkBoxHeader = (CheckBox)GridVwHeaderChckboxSrvr.HeaderRow.FindControl("chkboxSelectAll");
foreach (GridViewRow row in GridVwHeaderChckboxSrvr.Rows)
{
CheckBox ChkBoxRows = (CheckBox)row.FindControl("chkEmp");
if (ChkBoxHeader.Checked == true)
{
ChkBoxRows.Checked = true;
}
else
{
ChkBoxRows.Checked = false;
}
}
}
