Usage
Begin editing by:
-
double-clicking on the editable cell
-
pressing Enter, Space or typing an alphanumeric character when an editable cell is focused
When editing:
-
Esc discards the changes and exits edit mode
-
Enter and Shift+Enter save the changes and exit edit mode
-
Tab and Shift+Tab save the changes and focus the next and previous editable cell, respectively, while remaining in edit mode
Modes
Edit on Single Click
Single Click Edit is a mode that enables the user to begin editing by single-clicking on an editable cell.
new tab
<vaadin-grid-pro .items="${this.items}" edit-on-click>
<vaadin-grid-pro-edit-column path="firstName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="lastName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="email"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="profession"></vaadin-grid-pro-edit-column>
</vaadin-grid-pro>
Single Cell Edit
By default, when in edit mode, Tab and Shift+Tab move to the next and previous editable cell, respectively, while remaining in edit mode.
Single Cell Edit is a mode that makes tabbing from one cell to another exit from edit mode.
new tab
<vaadin-grid-pro .items="${this.items}" single-cell-edit>
<vaadin-grid-pro-edit-column path="firstName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="lastName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="email"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="profession"></vaadin-grid-pro-edit-column>
</vaadin-grid-pro>
Enter Next Row
Pressing Enter and Shift+Enter saves the changes and exits edit mode by default.
Enter and Shift+Enter can be made to focus the editable cell in the next and previous row, respectively, by using the Enter Next Row mode.
new tab
<vaadin-grid-pro .items="${this.items}" enter-next-row>
<vaadin-grid-pro-edit-column path="firstName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="lastName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="email"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="profession"></vaadin-grid-pro-edit-column>
</vaadin-grid-pro>
Edit Column
Editing is enabled on a per-column basis.
new tab
<vaadin-grid-pro .items="${this.items}" enter-next-row>
<vaadin-grid-column
header="Name (read-only)"
${columnBodyRenderer<Person>(
(person) => html`${person.firstName} ${person.lastName}`,
[]
)}
></vaadin-grid-column>
<vaadin-grid-pro-edit-column
header="Profession (editable)"
path="profession"
></vaadin-grid-pro-edit-column>
</vaadin-grid-pro>
Recommended Built-in Editors
Grid Pro features three recommended built-in editors: Text Field, Checkbox, and Select.
Editor | Usage Recommendation |
---|---|
Text | Editing basic text. |
Checkbox | Editing boolean (binary) values. |
Select | Selecting a single value from a set of options. |
Although Grid Pro can be configured to use any input field for editing, the built-in editors have better keyboard usability and rendering.
new tab
<vaadin-grid-pro .items="${this.items}" enter-next-row>
<vaadin-grid-pro-edit-column path="firstName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column
path="membership"
editor-type="select"
.editorOptions="${['Regular', 'Premium', 'VIP']}"
></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="subscriber" editor-type="checkbox">
</vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column
path="birthday"
${columnBodyRenderer<Person>(
({ birthday }) => html`${format(parseISO(birthday), 'MM/dd/yyyy')}`,
[]
)}
${columnEditModeRenderer<Person>(
({ birthday }) =>
html`
<vaadin-date-picker style="width: 100%" .value="${birthday}"></vaadin-date-picker>
`,
[]
)}
></vaadin-grid-pro-edit-column>
</vaadin-grid-pro>
Prevent Saving Changes
You can rollback changes when the entered input is incorrect or invalid.
new tab
<vaadin-grid-pro .items="${this.items}" @item-property-changed="${this.itemPropertyListener}">
<vaadin-grid-pro-edit-column path="firstName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="lastName"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="email"></vaadin-grid-pro-edit-column>
<vaadin-grid-pro-edit-column path="address.phone"></vaadin-grid-pro-edit-column>
</vaadin-grid-pro>
Distinguish Editable / Read-Only Cells
Editable cells are indicated with a hover effect by default, but you can give further help to users in distinguishing these by highlighting either editable or read-only cells. This is recommended for grids with both editable and read-only cells.
Highlight Editable Cells
Editable cells can be highlighted by applying the highlight-editable-cells
theme variant.
new tab
<vaadin-grid-pro theme="highlight-editable-cells" .items="${this.items}">
</vaadin-grid-pro>
Highlight Read-Only Cells
Read-only cells can be highlighted by applying the highlight-read-only-cells
theme variant.
new tab
<vaadin-grid-pro theme="highlight-read-only-cells" .items="${this.items}">
</vaadin-grid-pro>
You can also apply custom styling to both editable and read-only cells by targeting the editable-cell
part name in CSS.
:host(.editable-custom-effect) [part~="editable-cell"]:hover,
:host(.editable-custom-effect) [part~="editable-cell"]:focus {
background: var(--lumo-contrast-10pct);
}
:host(.editable-custom-effect) [part~="editable-cell"] {
background: var(--lumo-contrast-5pct);
}
Best Practices
Inline vs Non-Inline Editing
Inline editing is recommended when:
-
the user typically needs to make a lot of small changes to different items
-
quick editing is important.
Non-inline editing is preferable when:
-
there are a lot of columns/fields
-
users typically need to edit only one item at a time
-
adding new items is common (as you might want to have edit and create modes work the same way, and creating new items with inline editing isn’t recommended with Grid Pro)
-
any of the editors need to be bigger than a simple field, such as a Text Area or multi-select field of any kind
-
fields alone may be insufficient, for example when helpers, validation errors or other features are needed
-
explicit save/cancel actions are beneficial, for example to prevent accidental edits.
If your use case would benefit more from non-inline editing, consider using CRUD.
