Question

I have a LinkButton that has to postback to perform some logic.

Once it is finished, instead of loading the page back up in the browser, I want to leave it alone and pop open a new window.

So far, the best idea I’ve had is to put the LinkButton in an UpdatePanel, and have it render some JavaScript out when it reloads, yet I think that is totally hacky. Also, if I recall right, JavaScript within a update panel won’t run anyways.

Any other ideas?

Use LinkButton.PostBackUrl to set a different page to POST to, and some client script to get a new window (and the old target restored so that future postbacks work normally). The 2nd page can use PreviousPage to get access to any needed state from the original page.

<script runat='server'>    void lnk_Click(object sender, EventArgs e) {       // Do work    } </script>  <script type='text/javascript'>    var oldTarget, oldAction;    function newWindowClick(target) {       var form = document.forms[0];       oldTarget = form.target;       oldAction = form.action;       form.target = target;        window.setTimeout(          'document.forms[0].target=oldTarget;'          + 'document.forms[0].action=oldAction;',           200       );    } </script>  <asp:LinkButton runat='server' PostBackUrl='Details.aspx' Text='Click Me'   OnClick='lnk_Click'   OnClientClick='newWindowClick('details');' />
