View 7 RepliesFilling The Rest Of The Page With CSS?
Feb 22, 2010I have three Divs on the page and they are absolute positioned. Lets call them leftDiv,middleDiv,rightDiv and middleDiv width is 900px which is okay but the left and right divs should fill the remaining the left and right parts respectively no matter what screen size is.
The reason why I use absolute positioning is because it is the only way to use height:100% to fill the page.
So how can I fill the remaining parts?
Of course these divs separate page into three pieces according to their names imply.

Caching When Filling Panels With Content?
Jan 7, 2010I'm creating a group of surveys that query Salesforce ([URL] CRM) to generate survey questions dynamically.
The survey layouts are determined by a record type that gets passed in the QueryString. The page queries Salesforce and aggregates the questions/fields it should be using. Then it creates questions and adds them to a panel.
When I open one survey, things look great, and they work as designed. But on opening a separate survey, of a different type, the questions from the first survey are still in the questions panel, as if they are cached somewhere.
To see what I mean, open "Survey 1". Then open "Survey 2" in a new tab. Now re-open "Survey 1", but this time do it in a new tab. Compare the first "Survey 1" to the second "Survey 1", and you'll see that the second "Survey 1" has the questions from "Survey 2" added into it.
Is there something - or a way that - I should be clearing variables, public variables, sessions, or page/panel caches on every page load?
I define the array where the fields/questions are aggregated like this:
ASP Code:
public partial class _Default : System.Web.UI.Page
{
private static ArrayList field_names_use = new ArrayList { };

2) Is it ok to make a foreign key field for State inside the City table ?
3) Is it better to create new fields STATE and CITY inside SUPPLIER ?
