I have one url in which i have to send the some property values. My property like below

 public string MyValue
        {
            get { return MyValue; }
            set { MyValue = value; }
        }

Now I want to send this value as parameter to the url in window.open method in javascript.

window.open("../SearchPage/MySearch.aspx?MyValue=","left=20,top=20,width=500,height=500")
I tried to access in javascript like
'<%= MyValue %>".

But this is not coming. It is giving parser error. How to achieve this?

    If your JavaScript is located in a separate file, you can’t use <%= %> to define variable there, you should use hidden fields, cookies and similar stuff

    But if you could put js in aspx page, it should work

    <head runat="server">
    <title></title>
    <script type="text/javascript">
        alert('<%= MyProperty %>');
    </script>
</head>

    This works for me, where MyProperty is public string property in my aspx page, please make sure that you put quotes correctly

    EDIT

    Here is my page be

    public partial class WebForm1 : System.Web.UI.Page
{
    public string MyProperty { get; set; }
    protected void Page_Load(object sender, EventArgs e)
    {
        MyProperty = "aaaaaaaaa";
    }
}

    EDIT

    BTW

    public string MyValue
{
    get { return MyValue; }
    set { MyValue = value; }
}

    is not will cause StackOverflowException on set, you should create private variable for storing value 🙂

    private string _myValue;
public string MyValue
{
    get { return _myValue; }
    set { _myValue = value; }
}
