Am trying to pass the parameter using javascript
see ma code

node.navigateurl = "javascript: window.open('" + urlofthepage+ "',width=200,height=100);pname=" + trackid;

now in that page which am opening using above code, i have written the below code

C#

if (Page.Request.QueryString["pname"] != null)
          {
              string querystring = Page.Request.QueryString.Get("pname").ToString();
          }

But it is always returning null. Am passing value from there but unable to fetch it using QueryString.

What could be the reason?

Please refer this helpful to you

function Test() {
var value1 = 100;
var value2 = 200;
var value3 = 300;
window.open('<%=Url.Action("Index?param1=") %> ' + value1 + '¶m2=' + value2 + '¶m3=' + value3, "", "dialogWidth:875px;dialogHeight:600px");
}

I tried this

treebasiclinkchild.NavigateUrl = "javascript: window.open('Url.Action("+urlitempage+"?param1='" + proid + "');";

Even itried this also
treebasiclinkchild.NavigateUrl = "javascript: window.open('<%=Url.Action("+urlitempage+"?param1=) %> '" + proid + "');";

Not surprised.
Try:

C#

node.navigateurl = "javascript: window.open('" + urlofthepage+ "?pname=" + trackid + "',width=200,height=100)";

How can i pass more than one parameter ?

Add more:
A querysting is:
myDomain.com/pagename?firstparam=value&secondparam=value&thirdparam=value
So just add them to the url after teh '?' and separated by '&' characters.
