On New Page

If you want each group to start on a new page, you have two approaches. One is to configure with group header panel as follows, the other is to set the Fill Whole Page property for the group footer panel.

There is a problem when you only set On New Page to be true for the group header panel. You will find that the first page will have no details. Logi JReport Engine starts the detail panel from the second page. To solve this issue, you can use a formula to control this property. The formula will judge the property as being false for the first group, and being true for subsequent groups for displaying on a new page. However, if you feel this is too complicated, go to the group footer panel for the second approach.

  1. Create three formulas as follows:

    global:
    global integer i=0;

    groupHD:
    i=i+1;0

    FormulaControl:
    @groupHD;
    if (i>1)
    return true
    else
    return false

  2. Insert the formula global into the banded page header panel and assign it an initial value 0.
  3. Insert the formula groupHD into the group header panel so that for each group i will be calculated as i+1.
  4. Select the group header panel and use the formula FormulaControl to control its On New Page property. This formula will only return true for the property if i>1.

Repeat

The default value for Repeat is false. For one detail panel which spans a large space vertically to be shown in several pages, Logi JReport support the Repeat property if you want to see the group header information in each page. When the Repeat property is set true and group headers are visible, the group headers will duplicate on every page.

Notes:

  • When a page split occurs in the bottom blank part of the detail panel (or margins in the detail panel) and the Cross Page property in the detail panel is set true, the output will be: repeated group header + a slice of blank detail panel + group footer. It appears as though the repeated group headers are followed only by group footers without any detail panel. In order to solve this problem, you can resize the detail panel.
  • If the Repeat property is set true in both outer group header and inner group header, Logi JReport will treat the two group headers as a completely repeated object.
  • If the outer and inner group headers are set to be one completely repeated object, then when the page can only hold the group headers or has no enough space for the group headers, both outer and inner group headers will not be duplicated.
  • The Repeat property does not work for subreport.
