            top: 24px" Text="搜索" Width="72px" onmouseover="this.style.height='80px';this.style.color='red';this.style.backgroundColor='yellow';this.style.fontWeight='bold'"/>
警告：onmouseover不是Button有效属性。该如何解决？

Answer 1

在cs里写btnSearch.Attributes.Add("onmouseover","this.style.height='80px';this.style.color='red';this.style.backgroundColor='yellow';this.style.fontWeight='bold';");

Answer 2

INPUT style="Z-INDEX: 104; LEFT: 328px; POSITION: absolute; TOP: 360px" type="button"
value="Button"id="Button2"onmouseover="this.style.height='80px';this.style.color='red';this.style.backgroundColor='yellow';this.style.fontWeight='bold'">

Answer 3

在后台为此添加属性：
----------如在Page_load中加-----------------
Page_Load()
{
btnSearch.Attributes.Add("onmouseover","this.style.height='80px';this.style.color='red';this.style.backgroundColor='yellow';this.style.fontWeight='bold'");
}

Answer 4

<asp:Button ID="btnSearch" runat="server" Style="z-index: 106; left: 480px; position: absolute;
            top: 24px" Text="搜索" Width="72px" onmouseover="this.style.height='80px';this.style.color='red';this.style.backgroundColor='yellow';this.style.fontWeight='bold'"/>-------------------------------------------------------------------------------
定义个ＣＳＳ
.over{height:80px;color:red;back.....}<asp:Button ID="btnSearch" runat="server" Style="z-index: 106; left: 480px; position: absolute;
            top: 24px" Text="搜索" Width="72px" onmouseover="this.className='over'"/>
