The Group Buttons component allows grouping a series of buttons on a single line.
To see a live sample of the component you can go here.
In the Form Editor, drag the Group Buttons component from the Pallet onto the form, then select a dataprovider and a valuelist.
If the component does not appear in the pallet, it means you do not have the Bootstrap Extra Components package installed. Click "Get more components" at the top of the pallet to open the Servoy Package Manager and install it.
Group Buttons, like all components, have properties that can be modified at design time to set the appearance and behavior of the component. Select the component in the Form Editor to see a list of properties in the Component Properties Editor. Below are some common properties and how to set them at design time.
See the reference docs for Group Buttons for a complete list of its properties.
Group Buttons dataprovider can be set after the component has been added to the form or by setting it in dataprovider property, found in the Component Properties Editor.
Group Buttons input type can be set in inputType property, found in the Component Properties Editor. It can be single select (RADIO) or multi select (CHECKBOX).
IMPORTANT!
When the Group Buttons inputType property is set to CHECKBOX, then dataprovider property must be a variable that can contain multiples values, such as form or scope variable.
Example:
dataprovider is set as choice
Group Buttons valuelist can be set it in valuelist property, found in the Component Properties Editor and it should match the set dataprovider.
Example:
In order to get a group buttons with orders' ship countries, the followings settings should be made:
set the Group Buttons dataprovider:
if inputType is RADIO, then dataprovider can be either a table column (shipcountry) or another type of dataprovider
if inputType is CHECKBOX, then dataprovider must be a variable that can contain multiples values, such as form or scope variable
in case it doesn't exist, create a valuelist using Table values and shipcountry column as dataprovider
set the countries list in valuelist property of the Group Buttons
Like most components, Group Buttons have events, which allow you to execute some logic when something happens in the UI. Of course, the most common event for a Group Buttons is the onDataChange event, which is triggered when the component is clicked and the value is changed.
To Handle the event, double-click the value for the onDataChange property in the Properties Editor. You will see the Method Selection Wizard. You'll have the option to select an existing Method or create a new Method. The method will be called when the Group Buttons's onDataChange event is fired and the Event object will be passed to it.
See the Group Buttons reference for a comprehensive list of all events
