Default Value of a Widget

Version

Function Description

In some cases, you may need to set a default value for a widget. For example, you need to set a default query result during initialization when filtering and querying data in a report, or you need to write a default value during data entry. So how to set a default value for a widget?

To assign a default value to a widget, you can assign the value to the widget directly. You can also assign the value to the parameter directly if the parameter is bound to the widget. Since the parameter is bound to the widget, assigning the value to the parameter means assigning the default value to the widget.

Default Value of the Widget

You can set a default value for the widget on the Attribute panel of the widget, as shown in the following figure.

If the widget is a data entry widget, you can enter the value directly in the cell where the widget is located, as shown in the following figure.

Default Value of the Parameter

If the parameter is bound to the widget, assigning a value to the parameter means assigning a default value to the widget. Therefore, to assign a default value to the widget, you can assign the default value to the parameter if the parameter is bound to the widget. 

Note:

The format of the default value of the parameter must be the same as that required by the widget. For example, if the default value of the drop-down checkbox is New York;California, the default value of the parameter should also be New York;California.

Data Entry Widget

Application Scenario

In most cases, you want the initial value to exist in the widget before data entry on the data entry page. The initial value is actually the default value of the data entry widget, as shown in the following figure.

Implementation Method

You can enter the default value in the cell where the widget is located, as shown in the following figure.

Parameter Widget

Application Scenario

In most cases, you want to display the report content according to the default value on the parameter panel before you click the query button, as shown in the following figure.

Implementation Method

Set the default value when you define the template parameter, as shown in the following figure.

Select the parameter widget on the parameter page, choose Attribute > Advanced, and set the default value in Widget Value, as shown in the following figure.

During report preview, if you add the initial value of the parameter to the URL, the value in the URL will be displayed on the parameter page. For example, if you access a report by the URL http://localhost:8075/webroot/decision/view/report?viewlet=GettingStartedEN.cpt&Region=California, the value of the widget on the parameter page is the value in the URL, as shown in the following figure.
