ToolBar

The TreeGrid provides ToolBar support to handle treegrid actions. The toolbar property accepts either the collection of built-in toolbar items and ItemModelobjects for custom toolbar items or HTML element ID for toolbar template.

To use ToolBar, inject Toolbar module in the treegrid.

Built-in toolbar items

Built-in toolbar items execute standard actions of the treegrid, and it can be added by defining the toolbar as a collection of built-in items. It renders the button with icon and text.

The following table shows built-in toolbar items and its actions.

Built-in Toolbar Items Actions
ExpandAll Expands all the rows.
CollapseAll Collapses all the rows.
Add Adds a new record.
Edit Edits the selected record.
Update Updates the edited record.
Delete Deletes the selected record.
Cancel Cancels the edit state.
Search Searches the records by the given key.
Print Prints the treegrid.
ExcelExport Exports the treegrid to Excel.
PdfExport Exports the treegrid to PDF.

  • The toolbar has options to define both built-in and custom toolbar items.

Custom toolbar items

Custom toolbar items can be added by defining the toolbar as a collection of ItemModels. Actions for this customized toolbar items are defined in the toolbarClick event.

By default, Custom toolbar items are in position Left. You can change the position by using the align property. In the below sample, we have applied position Right for the Quick Filter toolbar item.

  • The toolbar has options to define both built-in and custom toolbar items.
  • If a toolbar item does not match the built-in items, it will be treated as a custom toolbar item.

Built-in and custom items in toolbar

TreeGrid have an option to use both built-in and custom toolbar items at same time.

In the below example, ExpandAll, CollapseAll are built-in toolbar items and Click is custom toolbar item.
