The Tree Grid will show scrollbar when the content exceeds the element width or height. The vertical and horizontal scrollbar will be displayed based on the following criteria.
- The vertical scrollbar appears when the total height of rows present in Tree Grid exceeds its element height.
- The horizontal scrollbar appears when the sum of column`s width exceeds Tree Grid element width.
The
Height
and
Width
property is used to set the Tree Grid Height and Width respectively.
The value of these properties can be a numeric value, pixel(px) or percentage (%).
In this demo, the
Height
and
Width
property of the Tree Grid is set to 400 and auto
respectively. Now, the Tree Grid will render with vertical scrollbar when the total height of rows
exceeds its element height and horizontal scrollbar will appear when the
total column width exceeds the element width.
