我有两个页面page1.aspx和page2.aspx,两个都有部分类的代码.
如何从page2.aspx访问page1.aspx上的公共属性消息？
如何从page2.aspx访问page1.aspx上的公共属性消息？
public string message { get; set; }
解决方法
如果一个是主页面,另一个是使用主页面的页面.
主页
<body>
<form id="form1" runat="server">
<div>
<asp:Literal runat="server" ID="txtOnMaster"></asp:Literal>
<br />
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
和背后的代码
public partial class Dokimes_StackOverFlow_MasterPage : System.Web.UI.MasterPage
{
public string TextToMaster
{
get { return txtOnMaster.Text; }
set { txtOnMaster.Text = value; }
}
protected void Page_Load(object sender,EventArgs e)
{
// here I find the control in the client page
Control FindMe = ContentPlaceHolder1.FindControl("txtOut");
// and if exist I set the text to client from the master
if (FindMe != null)
{
((Literal)FindMe).Text = "Get from Master Page";
}
}
}
现在是具有previus母版页的Page1.aspx
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Literal runat="server" ID="txtOut"></asp:Literal>
</asp:Content>
和代码
protected void Page_Load(object sender,EventArgs e)
{
// here I set the text on master page from client
((Dokimes_StackOverFlow_MasterPage)Master).TextToMaster = "Set from Client";
}
