I have a modal dialog, and need to be able refresh (i.e. force postback on) the parent form while the modal dialog is still open.

Is this possible?

Thanks,
Gary

You can reload the parent page which will refresh your content, but I don't know about specifically raising the Postback event in the parent page.

To reload you could write this to the client (Javascript): window.opener.location.href='page.aspx';

Thanks for your reply.

However, when I register the startup script from the modal dialog, I get the following error:-
"window.opener.location is null or is not an object"

Any ideas?

As far as I know, the only way this: window.opener.location.href='page.aspx'; will return NULL is if the modal dialog does not actually have an opener window OR if the opener window is closed before that call is made.

What I am actually trying to do is cause the parent form execute server side code (c#) while the modal dialog is still open. although the processing works fine, the page does not get refreshed until the dialog is closed and the next postback occurs.

Before I open the dialog, I assign a Session variable with a reference to the calling page. I can then use this reference to call functions/methods etc. in the parent page from within the modal dialog.

For example, one of the functions on the parent form does some processing then shows the results on the screen. However, If this is called from the modal dialog the processing works but the page does not show the results until the dialog is closed and another event on the parent page causes a postback.

Any help would be greatly appreciated.

On your parent page, after you have done your processing, have you tried writing window.location.reload() to the client?

Also, Script Callback may be something for you to look into http://msdn.microsoft.com/msdnmag/is...8/CuttingEdge/

The script doesn't get run. It's as if having a modal dialog (rather than non-modal) open prevents the page from reloading.

Hmmm. This was an oversight on my part so I appologize. This makes sense that your parent page will not execute commands while the modal window is open, its the same thing in Windows Development, if i spawn a modal window, execution on my parent form WILL not resume until I have closed the modal window. This is, of course, by design. I do not know if it is possible to override this behavior to the point where your parent window would refresh.
