Description
How can I change the scrolling position of the master Grid during the navigation of a non-scrollable child Grid?
Solution
- Handle the
navigate
event of the child Grid. - In the
navigate
event handler, based on theoffset
of the element, manually scroll the container of the parent Grid.
<div id="example">
<div id="grid"></div>
