Remarks

  • The only valid controls within the columns array are the TextBox, OptionsGroup, and DropDown.

  • The $rowIndex variable is only valid in expressions contained within children of the grid's columns. It's an integer that represents the element's relative row index and the count begins at one and increments by one. As shown in the schema's "columns": section, the $rowIndex is used for validation.

  • When validations are performed using the $rowIndex variable, it's possible to get the current row's value by combining the last() and take() commands.

    For example:

    last(take(<reference_to_grid>, $rowIndex))

  • The label property doesn't appear as part of the control but is displayed on the final tab summary.

  • The ariaLabel property is the accessibility label for the grid. Specify helpful text for users who use screen readers.

  • The constraints.width property is used to set the overall width of the grid. The options are Full, Medium, Small. The default is Full.

  • The width property on children of columns determines the column width. Widths are specified using fractional units such as 3fr, with total space being allotted to columns proportional to their units. If no column width is specified, the default is 1fr.
