Auto Fit , Maximum Width, Word Wrap

Here is a label:
Label product sales by region

We want to show it as:
Label product
sales by region

We can set the following:

Auto Fit=true enables the contents to grow horizontally but stop when the width becomes 1. Word Wrap=true enables the remaining contents to wrap downward if no space is left horizontally.

Style, ID, Class

The following is an example of using the Style, ID, Class property values as style sheet selectors in a CSS style file:

NewCSSFile.css:

@charset "GBK";
TextField {Background: #ff0000}
/*Style=LabelX*/
TextField[Style="LabelX"]{Background: #0000FF}
/*ID=W*/
TextField#W{Background: #FFFF00}
/*class=C*/
TextField.C{Background: #00FFFF}

Record Location

This property is to specify the calculation point for the properties of the object. Here is an example:

A report specifies to display Continued on Next Page for every page that has another following it. If this label is inserted in the PageHeader/PageFooter, then every page including the last page will contain the message. There is a way to write formulas that can resolve the problem:

Continue1:
global boolean j=true;
j=false;

Continue2:
pagenumber;
j=true;

Continue3:
pagenumber;
return j;

Insert Continue1 into the ReportHeader, Continue2 into the ReportFooter. To track the calculation, you can insert Continue3 into the PageFooter. If you do not want to see these formulas in view mode, you can suppress them.

Insert label Continued on Next Page in the PageHeader, and use Continue3 to control its property Invisible.

Set the property Record Location of the above label to be Page Footer, so that Continue3 returns value which is calculated in the PageFooter instead of in the PageHeader.

PageNumber is included in the formula to force it to execute as a page level formula in the order the formula is encountered rather than at the end of a group or report. For more information, see Formula levels.

Sortable

When you view your report in Page Report Studio, you can sort records in the data buffer on certain DBFields. You are allowed to use a label to control the sorting order, which can be enabled in JReport Designer by the Sortable property of the label object.

  1. In the Report Inspector, set the Sortable property of this label to true.
  2. Bind this label to a field on which you want to sort by setting this field as the value of the Bind Column property.
  3. Save and publish the report to JReport Server.
  4. Run the report in Page Report Studio, and you will see a sorting button besides the label, which can be clicked for sorting.

Filterable

When you view your report in Page Report Studio, you can set a series of conditions to filter the data buffer and reproduce the report. You are allowed to use a label to control the filter conditions for the data, which can be enabled in JReport Designer by the Filterable property of the label object.

  1. In the Report Inspector, set the Filterable property of this label to true.
  2. Bind this label to a field on which you want to filter by setting this field as the value of the Bind Column property.
  3. Save the report and publish it to JReport Server.
  4. Run the report in Page Report Studio. You can click the filtering button beside the label to filter the data, in the same way as the shortcut menu.
