This demo illustrates how to add the following items to the toolbar:
-
Predefined Controls
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. -
DevExtreme Components
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. -
Custom Elements
Specify a template for your custom element within a toolbar item. In this demo, the custom element displays the total group count.
