Client Side Set QueryString from Hidden Field

what about making onclick event instead of href:
<a onclick=showNewLink(); />

function showNewLink()
{
  window.open('Portfolio.aspx?StylistID='+StylistID.Value , '_blank', 'height=200,width=400,status=yes,resizable=yes');
}

For more info on window open, check:

I would rather use client side.
I've already tried response.redirect on the server also, but it didn't work.

Thanks

Response.Redirect("Portfolio.aspx?StylistID=" & Me.StylistID.Value & "")

Select allOpen in new window

My solution is client side (javascript) and it is opening a new window.
If you need to open the link in the same window, the javascript method should be:
function showNewLink()
{
  window.location = "Portfolio.aspx?StylistID="+StylistID.Value;
}

Note: In your server code, have you checked that the StylistID.Value is assigned in the client code only?

I've checked that there is a value in hidden field.
I'm not sure what you mean by window.location??
I just want to open another page.  In the page load of the page I want to open, I request the query string.
When I walk through the code, Response.Redirect("Portfolio.aspx?StylistID=" & Me.StylistID.Value & "")
I get the error Operator '==' incompatible with operand types 'Int32' and 'Object' before the page load fires on the page I want to open.

Thanks
