ASP.NET GridView控制項全選,反選,刪除選中項的實現

1、在GridVIew控制項中加上一個模板列，並在該列中加入CheckBox控制項，並加入需要的按鈕，如圖：

2、全選事件

<span style="font-size:18px;">//全選        protected void btn_all_Click(object sender, EventArgs e)        {            for (int i = 0; i <= GridView2.Rows.Count - 1; i++)            {                CheckBox cbox = (CheckBox)GridView2.Rows[i].FindControl("CheckBox1");                cbox.Checked = true;            }        }</span>

3、取消事件

<span style="font-size:18px;"> //取消        protected void btn_cancel_Click(object sender, EventArgs e)        {            for (int i = 0; i <= GridView2.Rows.Count - 1; i++)            {                CheckBox cbox = (CheckBox)GridView2.Rows[i].FindControl("CheckBox1");                cbox.Checked = false;            }        }</span>

4、反選事件

<span style="font-size:18px;"> //反選        protected void btn_others_Click(object sender, EventArgs e)        {            for (int i = 0; i <= GridView2.Rows.Count - 1; i++)            {                CheckBox cbox = (CheckBox)GridView2.Rows[i].FindControl("CheckBox1");                if (cbox.Checked == true)                {                    cbox.Checked = false;                }                else                {                    cbox.Checked = true;                }            }        }</span>

5、刪除選中項(原理：遍曆GridView控制項中所有CheckBox)

<span style="font-size:18px;"> //刪除選中項        protected void btn_del_Click(object sender, EventArgs e)        {                       for (int i = 0; i <= GridView2.Rows.Count - 1; i++)            {                CheckBox cbox = (CheckBox)GridView2.Rows[i].FindControl("CheckBox1");                if (cbox.Checked==true)                {                   //這裡執行刪除操作                }            }                   }</span>
