GridView中实现CheckBox的全选

 

用服务器端的方法： 
在页面上放一个gridview控件，配置好数据源，编辑列，添加一个模版列，再编辑模版，放入一个checkbox控件。代码如下：

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        DataKeyNames="AreaID" DataSourceID="SqlDataSource1">
        <Columns>
            <asp:BoundField DataField="AreaID" HeaderText="AreaID" ReadOnly="True" SortExpression="AreaID" />
            <asp:BoundField DataField="CityID" HeaderText="CityID" SortExpression="CityID" />
            <asp:TemplateField>
                <HeaderTemplate>
                    <asp:CheckBox ID="chkAll" runat="server" AutoPostBack="True" 
OnCheckedChanged="chkAll_CheckedChanged" />
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:CheckBox ID="chkItem" runat="server" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
后台cs代码：

protected void chkAll_CheckedChanged(object sender, EventArgs e)
{
    for (int i = 0; i < this.GridView1.Rows.Count; i++)
    {
        ((CheckBox)GridView1.Rows[i].FindControl("chkItem")).Checked = 
            ((CheckBox)this.GridView1.HeaderRow.FindControl("chkAll")).Checked;
    }
}
用脚本实现：

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        DataKeyNames="AreaID" DataSourceID="SqlDataSource1">
        <Columns>
            <asp:BoundField DataField="AreaID" HeaderText="AreaID" ReadOnly="True" 
SortExpression="AreaID" />
            <asp:BoundField DataField="CityID" HeaderText="CityID" SortExpression="CityID" />
            <asp:TemplateField>
                <HeaderTemplate>
                    <input id="chkAll"  onclick="SelectAll(this)"; type=checkbox>
                </HeaderTemplate>
                <ItemTemplate>
                    <input id="chkItem" type=checkbox>                
                 </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
再客户端写javascript

function SelectAll(chkbox)
{
   var box=chkbox;
   state=box.checked;    
   elem=box.form.elements;
   for(i=0;i<elem.length;i++)
   if(elem[i].type=="checkbox" && elem[i].id!=box.id)
    {
         if(elem[i].checked!=state)
         {
            elem[i].click();
         }
    }
 }

我自己的。。

 <Columns>
                                <asp:TemplateField HeaderText="选择">
                                <HeaderTemplate>
                    <input id="chkAll"  onclick="SelectAll(this)"; type="checkbox">
                </HeaderTemplate>
              
                                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                                    <ItemTemplate>
                                        <asp:CheckBox ID="CheckBox1" runat="server" />
                                    </ItemTemplate>
                                    <HeaderStyle HorizontalAlign="Center" Width="5%" VerticalAlign="Middle" />
                                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />

js：

 function SelectAll(chkbox) {
             var box = chkbox;
             state = box.checked;
             elem = box.form.elements;
             for (i = 0; i < elem.length; i++)
                 if (elem[i].type == "checkbox" && elem[i].id != box.id) {
                     if (elem[i].checked != state) {
                         elem[i].click();
                     }
                 }
