General Category / EasyUI for React / Re: Possibility to get a DataGrid filter rows
|
on: February 05, 2020, 10:41:01 PM

closest I've found is to use the onFilterChange event
I tried it but to no avail I did it like this:
constructor(props){
super(props){
...
}
this.viewRows = [],
this.viewRowsLength = 0
}
renderCode = ({ value, row, rowIndex }) =>{
if (rowIndex < this.viewRowsLength) this.viewRows = this.viewRows.slice(0, rowIndex + 1);
this.viewRows[rowIndex] = row;
this.viewRowsLength = rowIndex;
return value
};
<DataGrid>
...
<GridColumn
render = { this.renderCode }
field="code" title="Code" width="10%"/>
...
...
<DataGrid/>
But maybe possible to make it more simple? |

General Category / EasyUI for React / [SOLVED] DataGrid render only first time
|
on: January 24, 2020, 01:43:58 PM

Hello! EasyUI react didn't have the PropertyGrid component. Because I made it from DataGrid like a fragment code bellow. My component gets a new data. State is change but render DataGrid with a new data does not happen. Render happened only one time when new data is taken. "Data" is an array with always length 18. Each element is an object row like a: {"nameField": "code", "valueField": null, "titleField": "Код", "groupField": "Основные",
"editorField": "text", "rules": ["required", "positive"] },
I don't understand why this is so Please help me fix this trouble Thanks import React, { Component } from 'react'
import { ComboBox, DataGrid, GridColumn, SwitchButton, TextBox, Tooltip, ComboTree } from 'rc-easyui'
import ContextMenu from '../context-menu'
import ErrorBoundry from '../error-boundry'
import CodeEditor from "./item-code-editor";
export default class ItemDetail extends Component {
constructor(props) {
super(props);

this.validateRules= {
//const n = value ? String(value).trim().length : 0;
//return value.length === parseInt(param[0], 10);
