DataGrid/TreeList — Column Chooser Customization

The Column Chooser allows users to hide columns at runtime. In our v23.1 release cycle, we introduced 3 new Column Chooser options.

Our new selection property allows you to configure selection options within the Column Chooser window. Available options include:

• Recursive selection - you can choose whether parent element selection affects child/nested elements.
• "Select all" check box.
• Select a column by clicking its label.

For additional search customization within the Column Chooser, you can define a search configuration object. For example, you can specify a placeholder and implement custom value change handling logic:

import React from 'react';  
import 'devextreme/dist/css/dx.light.css';  

import DataGrid, { 
    ColumnChooser,  
    ColumnChooserSearch,  
    // ...
} from 'devextreme-react/data-grid'; 

const searchEditorOptions = {  
    placeholder: 'Search column',  
    mode: 'text', 
    onValueChanged: (e) => { 
        // handle the value change here 
    } 
}; 

export default function App() {  
    return (  
        <DataGrid ... >  
            <ColumnChooser ... > 
                <ColumnChooserSearch 
                    enabled={true} 
                    editorOptions={searchEditorOptions} 
                    // ... 
                /> 
            </ColumnChooser> 
        </DataGrid>  
    ); 
} 

 Additionally, our new position property allows you to set display location for the Column Chooser.

import React from 'react';  
import 'devextreme/dist/css/dx.light.css';  

import DataGrid, { 
    ColumnChooser,  
    Position,  
    // ... 
} from 'devextreme-react/data-grid'; 

export default function App() {  
    return (  
        <DataGrid ... >  
            <ColumnChooser ... > 
                <Position 
                    my="right top" 
                    at="right bottom" 
                    of=".dx-datagrid-column-chooser-button" 
                /> 
            </ColumnChooser> 
        </DataGrid>  
    );  
}

DataGrid/TreeList/PivotGrid/Gantt — Header Filter Customization

You can now personalize search preferences and the look of the search box within column header filters. You can configure the search box to function as a TextBox component, define comparison rules, and establish a timeout/delay (in milliseconds).

Use the search configuration object to globally configure search settings or use the columns[].headerFilter.search configuration object to make changes to individual columns. Use the fields[].headerFilter.search property to configure search settings in the Pivot Grid.

import React from 'react';  
import 'devextreme/dist/css/dx.light.css';  
  
import PivotGrid, { 
    HeaderFilter,  
    Search,  
    // ... 
} from 'devextreme-react/data-grid'; 
  
const searchEditorOptions = {  
    placeholder: 'Search value',  
    mode: 'text'  
}; 
  
export default function App() {  
    return (  
        <PivotGrid ... >  
            <HeaderFilter ... > 
                <Search 
                    editorOptions={searchEditorOptions} 
                    enabled={true} 
                    timeout={700} 
                    mode="equals" 
                /> 
            </HeaderFilter> 
        </PivotGrid>  
   );  
}
