Passing variables between pages...

[markgrizzle]

Hi,
My page_1 allows you to look up data with listbox_1. I needed to pass listbox_1.SelectedValue to page_2 so I added an id variable to the page_2 url like page_2.aspx?id = 123.Page_2 loads, sees the variable, sets listbox_2.SelectedValue to the right value, and refreshes the textbox.

But when I try to edit record data on page_2, the update procedure doesn't see the new value I entered in the textbox, and I can't click another row in listbox_2 either. It defaults back to the selected value I passed from page_1.

I think it's related to the variable in the url, since everything worked before I made the change. Can anyone point me in the right direction? I understand I can probably use session variables and/or master pages, but I'm new to this, and would ideally like a simple solution to finish this project.

Thanks in advance,
Mark

it looks like the page load is firing each time I try to update data on page_2, or try to use listbox_2. Sort of like an infinite loop.

So I guess my question is really, how do I pass the variable without appending it to the URL, since I need to stay on page 2 and edit data repeatedly.

ok, so I'm using session variables now, since I need to make multiple edits on page_2. page_1's url button click event looks like session("id") = 123.

page_2 loads and filters appropriately. Then I empty the session variable, so form edit/updates (which trigger page_load) don't have a session variable to use any more.

getting there...

ok, figured it out. The first time page_2 loads, I use the session variable to filter, then clear them out.

Subsequent page loads (due to data updates on the page) don't reload the original data, since the page_load event tests for the session variable before filtering.

Thanks tek-tips!
