DevExtreme jQuery - Customize Cells

Customize the Value and Text

Use the customizeText function to customize the text displayed in cells. Note that this text is not used to sort, filter, and group data or calculate summaries.

jQuery
JavaScript
$(function() {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            dataField: "Price",
            customizeText: function(cellInfo) {
                return cellInfo.value + "$";
            }
        }]
    });
});
Angular
TypeScript
HTML
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    constructor() {
        // Uncomment the line below if the function should be executed in the component's context
        // this.priceColumn_customizeText = this.priceColumn_customizeText.bind(this);
    }

    priceColumn_customizeText (cellInfo) {
        return cellInfo.value + "$";
    }
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})
<dx-data-grid ... >
    <dxi-column dataField="Price" [customizeText]="priceColumn_customizeText"></dxi-column>
</dx-data-grid>
Vue
App.vue
<template>
    <DxDataGrid ... >
        <DxColumn
            data-field="Price"
            :customize-text="priceColumn_customizeText"
        />
    </DxDataGrid>
</template>

<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DxDataGrid, {
    DxColumn
} from 'devextreme-vue/data-grid';

export default {
    components: {
        DxDataGrid,
        DxColumn
    },
    methods: {
        priceColumn_customizeText(cellInfo) {
            return cellInfo.value + '$';
        }
    }
}
</script>
React
App.js
import React from 'react';

import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DataGrid, {
    Column
} from 'devextreme-react/data-grid';

class App extends React.Component {
    constructor(props) {
        super(props);

        // Uncomment the line below if the function should be executed in the component's context
        // this.priceColumn_customizeText = this.priceColumn_customizeText.bind(this);
    }

    priceColumn_customizeText(cellInfo) {
        return cellInfo.value + '$';
    }

    render() {
        return (
            <DataGrid ... >
                <Column
                    dataField="Price"
                    customizeText={priceColumn_customizeText}
                />
            </DataGrid>
        );
    }
}
export default App;

To use the text displayed in cells in those data processing operations, specify the calculateCellValue function instead. It populates a column with custom values and allows you to create unbound columns - columns that are not bound to any individual data field. In the following example, this function combines full names using data from the firstName and lastName fields:

jQuery
JavaScript
$(function() {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            caption: "Full Name",
            calculateCellValue: function (rowData) {
                return rowData.firstName + " " + rowData.lastName;
            }
        }]
    });
});
Angular
TypeScript
HTML
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    constructor() {
        // Uncomment the line below if the function should be executed in the component's context
        // this.fullNameColumn_calculateCellValue = this.fullNameColumn_calculateCellValue.bind(this);
    }

    fullNameColumn_calculateCellValue (rowData) {
        return rowData.firstName + " " + rowData.lastName;
    }
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})
<dx-data-grid ... >
    <dxi-column caption="Full Name" [calculateCellValue]="fullNameColumn_calculateCellValue"></dxi-column>
</dx-data-grid>
Vue
App.vue
<template>
    <DxDataGrid ... >
        <DxColumn
            caption="Full Name"
            :calculate-cell-value="fullNameColumn_calculateCellValue"
        />
    </DxDataGrid>
</template>

export default {

        DxColumn
    },
    methods: {
        fullNameColumn_calculateCellValue(rowData) {
            return rowData.firstName + ' ' + rowData.lastName;
        }

    }

    fullNameColumn_calculateCellValue(rowData) {
        return rowData.firstName + ' ' + rowData.lastName;
    }

    render() {

Some features are disabled in columns with calculated values. Refer to the calculateCellValue description for a list of disabled features and the options that enable them.

Customize the Appearance

Cell appearance is customized using a column's cellTemplate. In Angular and Vue, you can declare the template in the markup. In React, you can use a rendering function (shown in the code below) or component:

Angular
HTML
TypeScript
<dx-data-grid ... >
    <dxi-column dataField="Title" cellTemplate="cellTemplate"></dxi-column>
    <div *dxTemplate="let cell of 'cellTemplate'">
        <div style="color:blue">{{cell.text}}</div>
    </div>
</dx-data-grid>
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxDataGrid ... >
        <DxColumn
            data-field="Title"
            cell-template="grid-cell"
        />
        <template #grid-cell="{ data }">
            <div style="color:blue">{{ data.cell.text }}</div>
        </template>
    </DxDataGrid>
</template>

<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DxDataGrid, {
    DxColumn
} from 'devextreme-vue/data-grid';

export default {
    components: {
        DxDataGrid,
        DxColumn
    },
    // ...
}
</script>
React
App.js
import React from 'react';

import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DataGrid, {
    Column
} from 'devextreme-react/data-grid';

const renderGridCell = (data) => {
    return <div style={{ color: 'blue' }}>{data.cell.text}</div>;
}

class App extends React.Component {
    render() {
        return (
            <DataGrid ... >
                <Column
                    dataField="Title"
                    cellRender={renderGridCell}
                />
            </DataGrid>
        );
    }
}
export default App;

If you use jQuery alone, use DOM manipulation methods to combine the HTML markup for cells. To apply this markup, use the cellTemplate function as shown in the following code:

jQuery
JavaScript
$(function() {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            dataField: "Title",
            cellTemplate: function(element, info) {
                 element.append("<div>" + info.text + "</div>")
                        .css("color", "blue");
            }
        }]
    });
});

While cellTemplate customizes data cells only, the onCellPrepared function can customize any cell. Unlike cellTemplate, this function does customizations after a cell is created, so you cannot use it to change the cell value. Check the rowType field of the function's argument to detect the UI element that owns the cell.

jQuery
JavaScript
CSS
$(function() {
    $("#dataGridContainer").dxDataGrid({
        // ...
        onCellPrepared: function(e) {
            if (e.rowType == "detailAdaptive") {
                e.cellElement.addClass("adaptiveRowStyle"); 
            }
        }
    });
});
.adaptiveRowStyle { 
    background-color: #cce6ff;
    font-size: 12pt
}
Angular
TypeScript
HTML
CSS
import { DxDataGridModule } from "devextreme-angular";
// ...
export class AppComponent {
    onCellPrepared (e) {
        if (e.rowType == "detailAdaptive") {
            e.cellElement.addClass("adaptiveRowStyle");
        }
    }
}
@NgModule({
    imports: [
        // ...
        DxDataGridModule
    ],
    // ...
})
<dx-data-grid
    (onCellPrepared)="onCellPrepared($event)">
</dx-data-grid>
.adaptiveRowStyle { 
    background-color: #cce6ff;
    font-size: 12pt
}

App.vue
<template>
    <DxDataGrid ...

            if (e.rowType == 'detailAdaptive') {
                e.cellElement.addClass('adaptiveRowStyle');
            }
        }
    }
}

<style scoped>
    .adaptiveRowStyle { 
        background-color: #cce6ff;
        font-size: 12pt
    }

        // Uncomment the line below if the function should be executed in the component's context
        // this.onCellPrepared = this.onCellPrepared.bind(this);
    }

    onCellPrepared(e) {
        if (e.rowType == 'detailAdaptive') {
            e.cellElement.addClass('adaptiveRowStyle');
        }
    }

    render() {
        return (
            <DataGrid ...
