The DataGrid includes an integrated toolbar that displays predefined and custom controls. To add or remove toolbar items, declare the toolbar.items array.
This demo illustrates how to add the following items to the toolbar:
Declare a toolbar item element and specify the name and properties that you want to customize. If a control does not need customization, include its name only. Ensure that items contain controls for all features that you enabled in your DataGrid. In this demo, we enable the columnChooser and add the "columnChooserButton" to the items array.
Configure the desired DevExtreme component within a toolbar item element. In this demo, we extended the toolbar's item collection with a Button and a SelectBox.
Specify a template for your custom element within a toolbar item. In this demo, the custom element displays the total group count.
