Good summary of the goal: show a “preview” popup that renders the values entered in the parent page’s user control (title, summary, description, date). and pointed out QueryString, and mentioned Session — both work but have important limits (length/exposure for query strings; server memory and web‑farm issues for sessions). Three practical, modern options follow (pick one that fits your deployment and security needs).

  1. Recommended — window.postMessage (robust, no server storage)

  • Parent opens the popup on a user click, then posts the data once the popup signals it is ready.

  • Parent (JS):

    // run inside click handler
var popup = window.open('/Preview.aspx', 'preview', 'width=900,height=700');
window.addEventListener('message', function recv(e) {
  if (e.origin !== location.origin) return;
  if (e.data === 'previewReady') {
    window.removeEventListener('message', recv);
    popup.postMessage({
      title: document.getElementById('TITLE_CLIENT_ID').value,
      summary: document.getElementById('SUMMARY_CLIENT_ID').value,
      body: document.getElementById('BODY_CLIENT_ID').value
    }, location.origin);
  }
});

  • Popup (JS):

    window.onload = function() {
  if (window.opener) window.opener.postMessage('previewReady', location.origin);
};
window.addEventListener('message', function(e) {
  if (e.origin !== location.origin) return;
  var d = e.data;
  document.getElementById('previewTitle').textContent = d.title || '';
  // populate other preview elements...
});

Notes: replace the CLIENT_ID placeholders with the rendered ClientID for your controls. Always check e.origin before accepting messages.

  1. Server-side temp storage (good for large content or when you want server rendering)
  • On click, save the form payload into Cache/DB with a GUID key, open Preview.aspx?key=GUID, and have Preview.aspx load the payload by key and expire it after a few minutes. This keeps payload out of URL and avoids large query strings.
  1. Simple same-origin option — localStorage
  • Parent: write JSON to localStorage then open popup.
  • Popup: read and clear that key on load. Quick and works when both pages share the same origin, but avoid for sensitive data (it persists until removed).

Troubleshooting tips

  • Always open popup from a direct user action (click) to avoid popup blockers.
  • If controls are inside a user control, use their ClientID (emit them into JS from server code) so the correct element is read.
  • Clean up temporary data (localStorage/cache) to avoid stale previews.
  • For web farms, prefer a distributed cache or DB rather than in‑process session/cache.

This gives a secure, practical preview workflow without duplicating the session/querystring pitfalls mentioned earlier.

and now i want on preview click popup page will display and
that show the look of your forum..

I hope U will got idea as U all r experience persons. and at least one of U will guide me..
Thanks for above all reply to me..

You can use Query String to pass a data beween the parent page and the popup window.

Use sessions;

create session for that;

session["Textbox"]=textbox1.text.toString();
