View as MD

Description

<vaadin-crud-edit-column> is a helper element for the <vaadin-grid> that provides a clickable and themable edit icon.

Typical usage is in a custom <vaadin-grid> inside a <vaadin-crud>.

Example: 

<vaadin-grid>
 <vaadin-crud-edit-column></vaadin-crud-edit-column>

 <vaadin-grid-column>
   ...

Properties

ariaLabel

Type: string

The arial-label for the edit button

autoWidth

Type: boolean

Automatically sets the width of the column based on the column contents when this is set to true.

For performance reasons the column width is calculated automatically only once when the grid items are rendered for the first time and the calculation only considers the rows which are currently rendered in DOM (a bit more than what is currently visible). If the grid is scrolled, or the cell content changes, the column width might not match the contents anymore.

Hidden columns are ignored in the calculation and their widths are not automatically updated when you show a column that was initially hidden.

You can manually trigger the auto sizing behavior again by calling grid.recalculateColumnWidths().

The column width may still grow larger when flexGrow is not 0.

footerPartName

Type: string | null | undefined

Custom part name for the footer cell.

footerRenderer

Type: GridHeaderFooterRenderer<any, GridColumn<any>> | null | undefined

Custom function for rendering the footer content. Receives two arguments:

  • root The footer cell content DOM element. Append your content to it.
  • column The <vaadin-grid-column> element.

See also: GridHeaderFooterRenderer

frozen

Type: boolean

When true, the column is frozen. When a column inside of a column group is frozen, all of the sibling columns inside the group will get frozen also.

frozenToEnd

Type: boolean

When true, the column is frozen to end of grid.

When a column inside of a column group is frozen to end, all of the sibling columns inside the group will get frozen to end also.

Column can not be set as frozen and frozenToEnd at the same time.

Type: string | null | undefined

Text content to display in the header cell of the column.

headerPartName

Type: string | null | undefined

Custom part name for the header cell.

headerRenderer

Type: GridHeaderFooterRenderer<any, GridColumn<any>> | null | undefined

hidden

Type: boolean

When set to true, the cells for this column are hidden.

path

Type: string | null | undefined

Path to an item sub-property whose value gets displayed in the column body cells. The property name is also shown in the column header if an explicit header or renderer isn't defined.

renderer

Type: GridBodyRenderer<any, GridColumn<any>> | null | undefined

Custom function for rendering the cell content. Receives three arguments:

  • root The cell content DOM element. Append your content to it.
  • column The <vaadin-grid-column> element.
  • model The object with the properties related with the rendered item, contains:
    • model.index The index of the item.
    • model.item The item.
    • model.expanded Sublevel toggle state.
    • model.level Level of the tree represented with a horizontal offset of the toggle button.
    • model.selected Selected state.

resizable

Type: boolean | null | undefined

When set to true, the column is user-resizable.

rowHeader

Type: boolean

When true, the cells for this column will be rendered with the role attribute set as rowheader, instead of the gridcell role value used by default.

When a column is set as row header, its cells will be announced by screen readers while navigating to help user identify the current row as uniquely as possible.
