vs2005 GridView控件怎么选中一行？？

tiger波波 2009-02-02 11:16:15

现在能在GridView控件里启用选定内容来选定一行，但每次都要点那个选中按钮，有没有什么办法，不启用选定内容，而是通过代码来选定一行，就是说没有选中按钮，而是用鼠标点中哪行就选择哪行，谢谢

HTML:
<script type="text/javascript">
var oldrow=null;
var currentcolor=null;
var oldcolor=null;
function selectx(row)
{
if(oldrow!=null)
{
oldrow.style.backgroundColor=oldcolor;
}
row.style.backgroundColor='#99ccff';
oldrow=row;
oldcolor = currentcolor;
}
</script>

.cs:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onmouseover", "if(this!=oldrow){currentcolor=this.style.backgroundColor;this.style.backgroundColor='PeachPuff',this.style.fontWeight='';}");
e.Row.Attributes.Add("onmouseout", "if(this!=oldrow){this.style.backgroundColor=currentcolor;this.style.fontWeight='';}");
e.Row.Attributes.Add("onclick", e.Row.ClientID.ToString() + ".checked=true;selectx(this)");
}
}

现在有空。。。随便给你写个简单的例子好了

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="CMET.Web.test" %>



<html>

<head>

    <title>test</title>

    <meta http-equiv="Content-Type " content="text/html;   charset=gb2312 ">

</head>

<body>

    <form id="form1" runat="server">

    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowDataBound="GridView1_RowDataBound">

        <Columns>

            <asp:BoundField DataField="ID" HeaderText="ID" />

            <asp:BoundField DataField="Name" HeaderText="Name" />

        </Columns>

    </asp:GridView>

    </form>

</body>

</html>



using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Data;

namespace CMET.Web

{

    public partial class test : System.Web.UI.Page

    {



        protected void Page_Load(object sender, EventArgs e)

        {

            if (!IsPostBack)

            {

                DataTable dt = new DataTable();

                DataColumn dc = new DataColumn("ID", typeof(string));

                DataColumn dc2 = new DataColumn("Name", typeof(string));

                dt.Columns.Add(dc);

                dt.Columns.Add(dc2);

                

                for (int i = 0; i < 10; i++)

                {

                    DataRow dr = dt.NewRow();

                    dr["ID"] = i.ToString();

                    dr["Name"] = "Name" + i.ToString();

                    dt.Rows.Add(dr);

                }

                this.GridView1.DataSource = dt;

                this.GridView1.DataBind();

            }

        }



        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

        {

            e.Row.Attributes.Add("onclick", "window.alert('您选择了第"+(e.Row.RowIndex+1).ToString()+"行');");

        }

    }

}

谢谢，这个可以实现。但是效果不太一样，选中了第二个，第一行颜色没变回来
