gridview

girdView我想是我们在进行web编程的过程中用得太多了，可是，正是太过熟悉，可能会有一些东西我们没有意识到，下面就通过一些简单效果来走进girdView控件。

实现如下效果：

1、增加鼠标动作

2、为包含有特定值的行改变样式

3、客户端隐藏特定的列

4、一次删除多条数据

5、在gridview之外的地方显示当前的页码

说明：所用数据库为pubs数据库中的authors。界面设计如下：

后台代码：

[csharp]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace gridView
{
    public partial class _3 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                for (int i = 1; i <=GridView1.Rows.Count; i++)
                {
                    DropDownList1.Items.Add(i.ToString());
                }
            }
        }

        protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType== DataControlRowType.DataRow)
            {
                //e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.backgroundColor='#00ffee';");
                //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");

                e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00ffee';");
                e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c;");

            {
                string lbl = Convert.ToString(DataBinder.Eval(e.Row.DataItem,"state"));
                if (lbl=="CA")
                {
                    e.Row.BackColor = System.Drawing.Color.LimeGreen;
                }

            foreach (GridViewRow gr in GridView1.Rows)
            {
                CheckBox chk = (CheckBox)gr.FindControl("itemchk");
                if (!chk.Checked)
