如何更改母版中的圖像？？？

Answer 1

        Image First = new Image(); 
        First = (Image)(Page.Master.FindControl("First"));
        if (First != null)
        {
            First.ImageUrl = "image-path";
        }

Answer 2

在master page的代碼隱藏文件中定義一個property

public string ImagePath
{

get { return First.ImageUrl; }
set { First.ImageUrl = value; }

}

在這樣的內容頁面中添加@MasterType頁面指令......

<%@ MasterType VirtualPath="~/master1.master" %>

tow.aspx頁面加載設置該屬性...

protected void Page_Load(object sender, EventArgs e)

{

  ((master1)this.Master).ImagePath= "image_path";

}

Answer 3

((master)this.Master).image.Src = "~/images/titles/accesscontrol.jpg";

一步到位
