Creating a template format in the grid dinamically.

Dear all,
we have a requirement to create custom template columns in the grid for allowing a modal, i.e. a button.

We have crafted the following function

   static createButtonElement(idbuttonIdclickCallback)

        let createButtonClassNode = React.createElement('i', {class:'small material-icons'}, 'search')
        let button = React.createElement('button', {'id': buttonId'class':'small material-icons' ,'onclick': clickCallback}, [createButtonClassNode])
        let scriptNode = React.createElement('script', {'id':id'type':'text/x-template'},button);
        return scriptNode;
We put that in this.selections
But for somewhat reason we are not able to show it directly to the grid. And we create an array this.realCols
where we put the real directives.

const Selections = ({ selections }) => (
        selections.map(item => (

        if (col.Fields.length > 0) {
            let field = col.Fields[0]
            let selectedValues = field.SelectionValues
            let item = null
            if (selectedValues != null) {

                console.log("Columnas :" + col.Id)
                let refColId = "#col" + col.Id
               console.log("creating template id " + refColId)
                item = React.createElement(ColumnDirective,
                        field: field.Name,
                        template: refColId,
                        headerText: col.Header,
                        type: "string"
                if (callback != null)
            return item
  render() {
        return (
        <div className='control-pane'>
            <div className='control-section'>
                <div className='col-md-9'>
                <Selections selections={this.selectionNodes} />
            <GridComponent dataSource={this.state.data}
                        ref={grid => this.gridInstance = grid}
                        <ColumnsDirective children={this.realCols}>
                        <Inject services={[PageToolbarFilterEdit]} />

Any suggestions?

Hi Giorgio, 
Thanks for contacting Syncfusion support, 
We have validated your query with provided the information and we have created a sample with bind a button on Grid Column using column template feature. Please refer the below code example, Documentation and sample for more information. 
import './App.css'; 
import { ButtonComponent } from '@syncfusion/ej2-react-buttons'; 
.   .    .    . 
class Parent extends React.Component { 
    constructor(props) { 
        .    .    .     . 
    gridTemplate(props) { 
       // We have bnd the button on template column 
        return (<div className='custId'> 
            <ButtonComponent cssClass='e-primary' content={props.CustomerID} onClick={this.templateBtnClk} ></ButtonComponent> 
    columns = [ 
        .   .    .    . 
    templateBtnClk(args) { 
   // you can bind the Modal pop-up here 
    componentDidMount() { 
        this.gridInstance.columns[3].template = this.gridTemplate.bind(this); // Define the template column for dynamic columns scenario 
    render() { 
        return ( 
            <div className="Parent" > 
                <div className='control-section'> 
                    <GridComponent ref={grid => this.gridInstance = grid} dataSource={orderData} allowFiltering={true} allowPaging={true} allowSorting={true} 
                        toolbar={this.toolbarOptions} allowSelection={true} 
                        editSettings={this.editOptions} columns={this.columns}> 
                        <Inject services={[Filter, Page, Edit, Toolbar, ExcelExport, PdfExport, Sort]} /> 
export default Parent; 
Please get back to us, if you need further assistance.

Hi Giorgio, 
For rendering “CheckBox” component while editing, you can set editType as “booleanedit”. Please refer to the below code example and documentation link for more information.   
let coldef = {"field":"Included","headerText":"Included","allowEditing":true,"type":"boolean","editType":"booleanedit","displayAsCheckBox":"true"} 
Please get back to us if you need any further assistance on this.
