destroy function on tab change

(0) ShareShare

Posted on by 87

Hello.

 

We have multiple of the same PCF app, on different tabs in the same model driven app form.

 

Is it possible to get a destroy function when the tab is changed?

 

Right now we are doing some unsupported calls into Xrm.Page.ui.tabs, to see if the component is on a active tab and then running the code we want to run, when the app is no longer in the current tab

 

https://www.codepile.net/pile/lBnP92e0

 

import {useState, useEffect} from "react";

export const useIsTabActive = (tab: any) => {
 const [isActive, setIsActive] = useState<boolean>(true);

 useEffect(() => {
 tab.addTabStateChange(changeEventStatus);
 }, []);

 const changeEventStatus = (event: any) => {
 const tabs: any[] = Object.values((window as any).Xrm.Page.ui.tabs._collection);
 const tabIndex = tabs.findIndex(_ => _._controlName == event._eventSource._controlName);
 const isAct = (window as any).Xrm.Page.ui.tabs.get(tabIndex).getDisplayState() == "expanded";
 setIsActive(isAct);
 }

 return isActive;
};

    I've checked if my PCF is on an active tab by checking my container width. I've set 'trackContainerResize' to true in the index and then looked for an allocated width of greater than 0. If it's 0 then your PCF is not on an active tab.

     

     

    context.mode.trackContainerResize(true);
    context.mode.allocatedWidth > 0
