In this blog, I want to share how we can use the Prefill Service <\/strong>feature in adaptive forms.<\/p>\n\n\n\n

<\/p>\n\n\n\n

What is the use of Prefill Service?<\/strong><\/p>\n\n\n\n

It is used to prepopulate the form with given values.
<\/p>\n\n\n\n


<\/p>\n\n\n\n

How to create Prefill Service?<\/strong><\/p>\n\n\n\n

For creating prefill service you need to create an osgi component. For example:-<\/p>\n\n\n\n

In my form I have two text boxes as shown.
<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

So to prefill these values while Preview, <\/strong>I am making the osgi component. My class name is MyPrefillAdaptiveForm.class<\/strong><\/p>\n\n\n\n

Where the Prefill service option is available in form?<\/strong><\/p>\n\n\n\n

In the form container dialog, under Basic you can find the dropdown to select your Prefill Service.<\/strong>
<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n
