Hi, Ed
i just read from the forum you sent.... if you don't mind, can you give more
example ? because i based on the in instruction , i still cant get it. An no
idea for this part
getBodyContainer().addOnLoadModifier(
new ClickOnceOnLoadModel( modalWindowOpeningLink ), null
);
As my code structure this like this way
public class LastThirtyDaysLineChart extends CommonPage{
// main contructor. Initial the page to show what
public LastThirtyDaysLineChart () {
// 1. display the feedback panel
add(new FeedbackPanel("feedback"));
// 2. display the component defined in form
add(new LastThirtyDaysLineChartForm("LastThirtyDaysLineChartForm"));
}
// the form declare the component in order display in the web browser
private class LastThirtyDaysLineChartFormextends Form{
// 3. so, is the main source to get the data from Database in order
to generate the chart
generate Time series chart...
}
}
So, in which part i need to generate the ModalWindow with no onClick event
...Mean once this page is load, the modal window will auto prompt on
screen...
Can you give some instruction to me ? thanks in advance
