[Javasript]

<script type="text/javascript"> 
    function ChangeProjectImage(obj) { 
     var ctrl = document.getElementById(obj.id); 
     ...code... 
    } 
</script>

[HTML - 菜單控制]

<asp:Menu ID="Menu1" runat="server" Orientation="Vertical" Font-Names="Verdana" Font-Size="12px" 
     CssClass="Menu"> 
</asp:Menu>

你在你的項目有JQuery的？或者你可以使用jQuery？ – Praveen

這個項目中沒有JQuery，我還沒有使用它。 – TroyS

經過大量研究後，似乎不可能。我可能不得不使用樣式無序列表。 – TroyS

我結束了使用DataGrid控件。

HTML

<div style="clear: left; padding-right: 5px;"> 
     <asp:GridView ID="GridView1" runat="server" ShowHeader="False" GridLines="None" BorderStyle="None" CssClass="MyGridView"> 
      <Columns> 
       <asp:ImageField> 
        <ItemStyle Height="16px" Width="16px" /> 
       </asp:ImageField> 
      </Columns> 
     </asp:GridView> 
</div>

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    If Me.IsPostBack Then 

    Else 
     ...code to fill datagrid 

     For Each gr As GridViewRow In GridView1.Rows 
      ...code 
      gr.Attributes.Add("onmouseover", "ChangeProjectImage(""productimages/" & gr.Cells(2).Text & """,""" & gr.Cells(3).Text & """)") 
      gr.Attributes.Add("onmouseout", "ChangeProjectImage(""images/display2.png"",""140"")") 
     Next   
    End If 

End Sub

的JavaScript

function ChangeProjectImage(imgpath, resizeheight) { 
    var img1 = document.getElementById"MainContent_LeftTopTabContainer_ThumbTabPanel_Image2") 
    img1.style.height = resizeheight 
    img1.src = imgpath; 
    }
