Gridview技巧3

 新增一个模版列：

<asp:TemplateField HeaderText="选取">                    <HeaderTemplate>                        全选：<asp:CheckBox ID="CheckBox2" runat="server" OnCheckedChanged="CheckBox2_CheckedChanged1" AutoPostBack="True" />                    </HeaderTemplate>                    <ItemTemplate>                        <asp:CheckBox ID="CheckBox1" runat="server" />                    </ItemTemplate>                </asp:TemplateField>

 

注意：CheckBox2一定要启用AutoPostBack

后台代码：

protected void CheckBox2_CheckedChanged1(object sender, EventArgs e)    {        int i;        if (((CheckBox)sender).Checked)        {            for (i = 0; i < GridView1.Rows.Count; i++)            {                ((CheckBox)GridView1.Rows[i].FindControl("CheckBox1")).Checked = true;            }        }        else        {            for (i = 0; i < GridView1.Rows.Count; i++)            {                ((CheckBox)GridView1.Rows[i].FindControl("CheckBox1")).Checked = false;            }        }    }
