（1）根据内容设置GridView某些行，或单元格的颜色。

Code
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.Cells[8].Text == "USA")
            {
                e.Row.BackColor = System.Drawing.Color.Red;
                //e.Row.Cells[8].BackColor = System.Drawing.Color.Red;
            }
        }
    }

（2）GridView复选框实现全部选择。

Code
   protected void CheckBox2_CheckedChanged(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;
            }
        }
    }

（3）GridView导出表到excel文件。

提供了对分页的支持，如果需要屏敝某些列，将这些列的Visible属性设为false即可。需要注意的是，一定要对方法VerifyRenderingInServerForm(Control control)进行重载。

Code
   protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");
        // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

        bool bPage = GridView1.AllowPaging;
        if (bPage)
        {
            GridView1.AllowPaging = false;
            GridView1.DataBind();
        }

        this.GridView1.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();

        if (bPage)
        {
            GridView1.AllowPaging = true;
            GridView1.DataBind();
        }

    }
    public override void VerifyRenderingInServerForm(Control control)
    {
    }

（4）鼠标移到GridView某行时，动态改变该行的背景颜色。

Code
    protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow )
        {
            e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#C0C0FF';this.style.cursor='hand';");
            //当鼠标移走时还原该行的背景色
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor");
        }
    }

（5）GridView响应单击或双击行事件。

Code
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType==DataControlRowType.DataRow)
        {
            //e.Row.Attributes.Add("ondblclick", "ReKey('" + e.Row.Cells[2].Text+"')");
            //e.Row.Attributes.Add("onclick", "alert('" + e.Row.Cells[2].Text + "')");
            e.Row.Attributes.Add("ondblclick", "window.open('http://www.sina.com?name=" + e.Row.Cells[2].Text + "')");
            e.Row.Attributes["style"] = "Cursor:hand";
            // //键盘事件
            //e.Row.Attributes.Add("OnKeyDown", "GridViewItemKeyDownEvent('" + e.Row.Cells[1].Text + "')");

        }

    }

（6）GridView添加删除确认。

将原有的删除列转化为模板列，在页面上添加确认代码：

OnClientClick='return confirm("确认要删除吗？")'
