I am currently using antd-form-builder to build multiple JSON forms for different components and I have an issue with antd trying to use a checkbox to disable another input.. basically I have a function that returns the form meta fields and then in the onChange for the checkbox I am trying to set another field to become disabled
what I have managed to find so far is for the form ref there is a setFields function and I can use this to change the value of another field or the errors on that field through the onChange of the checkbox, however, I cannot change the disabled state of another field.
turns out, this cant be done .. and state variables should be used as mentioned in the issue here

I want to basically know if I am having rows selected to activate an input, the thing is
"selectionChange" event is not capturing when the selection is being changed I have a small example.
https://codesandbox.io/s/ag-grid-react-redux-events-forked-459v6?file=/index.js
What id expect to happen is to get the alert to show when something is selected on this example.
Turns out in React this property is onSelectionChange, following react pattern
Id like to show a popper with data in it which represents a history of searched suggestions on click, but replace that with the default autocomplete dropdown on type, and keep it unless the input is blank. One idea I thought would work was using a onChange handler to detect the length of input typed... which Ive not managed.
On click of the highlighted value Id like to redirect to another page. Currently I'm using json object to hold a few strings, with urls like this.
To achieve the desired results, we will be maintaining two seperate options searchHistory options & the default options. We can toggle between the options by checking if the input field is empty or user has entered something to search through the default options.
I've modified your code on sandbox. Following is the link.

I have used the following component in react,
https://www.npmjs.com/package/react-multiselect-checkboxes
I want to clear selected checkboxes because I have to recreate it with new options from another dropdown change event.
So is there any way from where I can clear selected checkboxes from parent component when another dropdown is changed
This is for react
The author of the libarary suggest that its behavior is based on react-select
Have you tried to use value prop?
see https://github.com/JedWatson/react-select#controllable-props
Additionally if you want to manipulate values in parent component you should use onChange callback then and store it somewhere (I assume state will be best place)
I am seeing this in Edge and IE.
I have a checkbox which is being initialized using initialValues to true.
On first visit its is displayed correctly as checked with a value of true, however after refreshing the page via the browser, the checkbox is not checked but still has a value of true. As i can continue to refresh the page the checkbox continues to switch in this way checked then unchecked on next refresh. redux form 7.2.3 react 15.6.2.
Thanks
The value of a checkbox is what will be associated with its name if it is checked. Checking a checkbox should not change the value, it should change the checked property.
This is not specific to redux-form, it is just how form elements are intended to work. It looks like redux-form wants to use value instead, and it doesn't work right.
In any case, I think you want to specifically handle the checked property with something like checked={value}.
Roy's answer is correct. Adding some redux-form context, passing checked to a Field component will override the normal behaviour. The normal behaviour is to compare if the value stored in redux-form's state is the same as the value prop specified on Field if so the checked prop is true.
So for example if the store state is values: { test: true } and your Field has value={true} then the end result is the checked prop is true.
The F5 refreshing toggle most likely suggests that your values initialization is changing on each refresh. It's hard to help you beyond a general statement like this without clear reproduction steps.
I'm using Semantic-React and I have component-filter which consists of checkbox groups. Every checkbox has id and I must pass them in order to filter the results.First idea was to perform method which would be called after checkbox onCLick(which would pass checkbox id). And in this method set in state an object and after every checkbox click change it. I remember, that in Jquery exists $('form').serialize() which everytime checks form elements and gets checked values automaticaly. Exists something like this in react, or semantic-ui react? I would be simplier to use such method than to create and control object in state
You should use "controlled components":
Filter component should keep a set of checked ids as part of state.
Checkbox checked property should be set to true if the set contains box id (and to false otherwise) in Filter component render.
Checkbox onChange should be handled by filter component and modify state.
Filter can access it's state handling checkbox onChange or button "Apply" onClick (or any other event handled by Filter component).
Be careful: setState is an async function and directly reading other component state can lead to data race, so state must be read after proper event fired by React. Also there are a bunch of state-keepers like Redux.
It is described in official docs here: https://reactjs.org/docs/forms.html
