Example

To execute the example, the HTML page must contain the TabSheet component named tabSheet (see. Example of Creating the TabSheet Component). Scroll the table downward, and change the scrollbars appearance so that they do not cover the whole table:

// Set the number of columns in the clipboard in asynchronous mode
tabSheet.setVerticalExpandVolume(2);
// Get the vertical scroll element
var hScrollBar = tabSheet.getVScrollBar();
// Scroll vertically 
hScrollBar.scrollTo(50, true);
// Change the scrolling panels appearance
tabSheet.setIsScrollBarPartial(true);

After executing the example the table is scrolled 50 pixels down, clipboard size in asynchronous mode for the table columns is set to 2, and the scrollbars do not cover the whole table:
