React TreeList - Customize Column Headers
The TreeList generates column headers based on the names of data fields by default. For example, if a data field is "fullName", the column header text is "Full Name".
Specify the columns.caption property to change the column header text.
jQuery
$(function() { $("#treeListContainer").dxTreeList({ // ... columns: [ { dataField: "CompanyName", caption: "Company" }, // ... ] }); });
Angular
<dx-tree-list ... > <dxi-column dataField="CompanyName" caption="Company"></dxi-column> </dx-tree-list>
import { DxTreeListModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxTreeListModule ], // ... })
If you need a more specific customization, define a custom template in the columns.headerCellTemplate property. This property accepts a function or template container.
jQuery
$(function() { $("#treeListContainer").dxTreeList({ // ... columns: [{ dataField: "Title", caption: "Position", headerCellTemplate: function (header, info) { $('<div>') .html(info.column.caption) .css('font-size', '16px') .appendTo(header); } }, { dataField: "Address", headerCellTemplate: $('<i style="color: black">Mailing Address</i>') }] }); });
Angular
<dx-tree-list ... > <dxi-column dataField="Title" caption="Position" headerCellTemplate="titleHeaderTemplate"> </dxi-column> <dxi-column dataField="Address" headerCellTemplate="addressHeaderTemplate"> </dxi-column> <div *dxTemplate="let info of 'titleHeaderTemplate'"> <p style="font-size:16px">{{info.column.caption}}</p> </div> <div *dxTemplate="let info of 'addressHeaderTemplate'"> <i style="color: black">Mailing Address</i> </div> </dx-tree-list>
import { DxTreeListModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxTreeListModule ], // ... })
To hide column headers, assign false to the showColumnHeaders property.
jQuery
$(function() { $("#treeListContainer").dxTreeList({ // ... showColumnHeaders: false }); });
Angular
<dx-tree-list ... [showColumnHeaders]="false"> </dx-tree-list>
import { DxTreeListModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxTreeListModule ], // ... })
