    vertical scrollbar refreshes the grid when scrolled to bottom Posts

    Hi Admin,

    We set the autoheight property to false and added a fixed height to get a vertical scrollbar. When we scroll to the bottom grid refreshes and as a result any new row that is added before scrolling disappears.

    regards,

    Nitin

    Hello Nitin,

    In the following example the ‘autoheight’ property is set to false and the vertical scrollbar does not refresh the grid when it is scrolled to the bottom of the grid. Please, make sure you are using the latest version of jQWidgets (3.7.1).
