Scrolling in JavaScript Grid control

30 Jul 2021 / 3 minutes to read

The scrollbar will be displayed in the grid when content exceeds the element width or height. The vertical and horizontal scrollbars will be displayed based on the following criteria:

The vertical scrollbar appears when the total height of rows present in the grid exceeds its element height.
The horizontal scrollbar appears when the sum of columns width exceeds the grid element width.
The height and width are used to set the grid height and width, respectively.

The default value for height and width is auto.

Set width and height

To specify the width and height of the scroller in the pixel, set the pixel value to a number.

Responsive with parent container

Specify the width and height as 100% to make the grid element fill its parent container. Setting the height to 100% requires the grid parent element to have explicit height.
