Help us shape the 2021 DevExtreme Roadmap.
Take our 5 minute survey.
Toolbar Customization
The DataGrid uses an integrated DevExtreme Toolbar component to display predefined and custom commands. To add or remove toolbar items, implement the onToolbarPreparing function. Use its parameter's toolbarOptions field to access the Toolbar's configuration object. This object includes the command collection: the toolbarOptions.items array.
This demo illustrates how to add the following items to the toolbar:
-
DevExtreme widgets
Specify a widget that you want to add and its options. 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. In this demo, the custom element displays the total group count. -
Predefined controls
The availability of predefined controls depends on whether a specific DataGrid feature is enabled. For example, this demo enables the columnChooser, and the toolbar displays the Column Chooser button. You can customize the predefined controls in the onToolbarPreparing function. Refer to its description for a code example.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
