      public DataGridColumn(GroupDataGrid<E> grid, String columnId, com.vaadin.flow.data.renderer.Renderer<E> renderer)
      Constructs a new DataGridColumn for use inside a GroupDataGrid.
      Parameters:
      grid - the grid this column is attached to
      columnId - unique identifier of this column
      renderer - the renderer to use in this column, must not be null

      Gets the owner of this column.
      Returns:
      the grid which owns this column

    • setApplicationContext

    • setClassNameGenerator

      public Grid.Column<E> setClassNameGenerator(com.vaadin.flow.function.SerializableFunction<E,String> classNameGenerator)
      Description copied from class: Grid.Column
      Sets the function that is used for generating CSS class names for cells in this column. Returning null from the generator results in no custom class name being set. Multiple class names can be returned from the generator as space-separated.

      If Grid.setClassNameGenerator(SerializableFunction) is used together with this method, resulting class names from both methods will be effective. Class names generated by grid are applied to the cells before the class names generated by column. This means that if the classes contain conflicting style properties, column's classes will win.

      Overrides:
      setClassNameGenerator in class Grid.Column<E>
      Parameters:
      classNameGenerator - the class name generator to set, not null
      Returns:
      this column

      Returns:
      true if the column can be used in grouping

    • setGroupAllowed

      public void setGroupAllowed(boolean groupAllowed)
      Sets whether the column can be used in grouping.

      This method enables/disables grouping by this column in UI. The column can still be grouped programmatically using GroupDataGrid.groupByColumns(Grid.Column[]) and other methods.

      The default value is true.}

      Parameters:
      groupAllowed - whether the column can be used in grouping
