Hi,

Assuming your UI Control is a link or action performing control, we can add the refresh the section/Other section / Harness in the Action tab of that property, by specifying the when condition.

Thanks Chandan but in customized control we can’t add WHEN conditions. I have already tried it. Even I doubt that it would perform those mentioned actions or not..!

Hi Akash,

You can use Pega JS refresh API into your JS code to refresh the section conditionally. [Pegasystems Documentation](https://community.pega.com/knowledgebase/articles/user-interface/refreshsection-public-js-api-control-actions)

```auto
function refresh_section_from_control(){
var options = { 
event: event
};
pega.api.ui.actions.refreshSection(options);
}

```

The above function refreshes the current section of the control when the function is called. You can call **refresh\_section\_from\_control()** function based on your logic inside the code.

Let me know if you have any more questions. Good Luck!
