GridView 的行高

[向东]

鼠标放上去 行加高 4px 移开行高 减少 4px
e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#cccccc',this.style.fontWeight='';alert(this.height);this.height = parseInt(this.height)+4;");
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor,this.style.fontWeight='';this.height = parseInt(this.height)+4;");

可是不行
offsetHeight 好像不可以改变
哪位高手 支援下 谢谢

var currTR=this;
function overTR(){
var trs = document.getElementById("setTbl").getElementsByTagName("tr");
for(var i in trs){
trs[i].onmouseover = function(){
var oldBgColor=this.bgColor;
var oldFontColor=this.style.color;
this.bgColor = "#0000FF";
this.style.color="#FFFFFF";
if(currTR != this&&currTR.tagName=="TR"){currTR.bgColor = oldBgColor; currTR.style.color=oldFontColor;}
currTR = this;
}
}
}
window.onload = function(){overTR();}

onmouseover="this.style.height=this.style.height-4"
这个倒是可以 可是FF不支持 IE7可以

因为你GridView的row默认没有行高，所以取this.height就只能得到值"",parseInt("")是不行的。
加一行代码：

    protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {
        //要先给height赋值
        e.Row.Attributes.Add("height", "50px");
        e.Row.Attributes.Add("onmouseover", 
            "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#cccccc';alert(this.height);this.height = parseInt(this.height)+4;");
    }

<table border="2">
<tr height="100px" onmouseover="this.height = parseInt(this.height)+4;" onmouseout="this.height = parseInt(this.height)-4;">
<td >dfdfdf</td>
</tr>
</table>

IE7支持 可是ff不支持
我很郁闷ff

e.Row.Attributes.Add("onmouseover", "c=this.style.height;this.style.height='80px'");
//当鼠标移开时还原高度
e.Row.Attributes.Add("onmouseout", "this.style.height=c");
