使用antd表时，如果选中了复选框，则清除该复选框

Question

I have a main component and a child component where I use antd table. The code does not throw any exception, and the selected ids are flowing correctly to the main component.

However the checkboxes are cleared after clicking on them, so I am not sure what am I missing here

Main component

import React, { Component } from 'react';
import { Input} from 'antd';
import Form from '../../components/uielements/form';
import Button from '../../components/uielements/button';
import Notification from '../../components/notification';
import { adalApiFetch } from '../../adalConfig';
import   ListPageTemplatesWithSelection  from './ListPageTemplatesWithSelection';


const FormItem = Form.Item;

class CreateModernSiteCollectionForm extends Component {
    constructor(props) {
        super(props);
        this.state = {Alias:'',DisplayName:'', Description:'', PageTemplateIds : []};
        this.handleChangeAlias = this.handleChangeAlias.bind(this);
        this.handleChangeDisplayName = this.handleChangeDisplayName.bind(this);
        this.handleChangeDescription = this.handleChangeDescription.bind(this);
        this.handleSubmit = this.handleSubmit.bind(this);
        this.handleRowSelect = this.handleRowSelect.bind(this);
    }

    handleRowSelect(ids) {
        this.setState({ PageTemplateIds: ids });
    }

    handleChangeAlias(event){
        this.setState({Alias: event.target.value});
    }

    handleChangeDisplayName(event){
        this.setState({DisplayName: event.target.value});
    }

    handleChangeDescription(event){
        this.setState({Description: event.target.value});
    }

    handleSubmit(e){
        e.preventDefault();
        this.props.form.validateFieldsAndScroll((err, values) => {
            if (!err) {
                let data = new FormData();

                    key: 'key',
                },

export default ListPageTemplatesWithSelection;

Answer 1

This is happening because child component is expecting the selectedRows prop but the main component is not passing it to it.

const rowSelection = {
    selectedRowKeys: this.props.selectedRows,
    //-----------------------------^^--------
    onChange: (selectedRowKeys) => {
        this.props.onRowSelect(selectedRowKeys);
    }
};

So when you select something, parent updates its state via onRowSelect prop. But it forgets to send the updated state back to the child via selectedRows prop. So the child doesn't know what row's have been selected and fallbacks to default unchecked behavior.

To fix it, just pass the PageTemplateIds state as selectedRows prop in your main component:

<ListPageTemplatesWithSelection 
    onRowSelect={this.handleRowSelect} 
    selectedRows={this.state.PageTemplateIds}
/>
