CellClick firing when sliding on a mobile

[pguzParticipant]

Hi,

In our mobile app, we render a grid in a web page. That grid is often larger than the screen, so the user scrolls the page using by dragging their finger around the screen. However, when the user lifts his finger, the cellclick event fires.

Is there a way of detecting a drag rather than a click in this circumstance?

Hi Paul,

cellclick is raised on tap, drag happens on tap and move on the Grid’s surface. I would suggest you to either use the Grid’s scrollbar for scrolling or use events like cellselect which happens when drag ends.

Thanks Peter.

Unfortunately, I can’t use cellselect as I am using singlerow selectionmode.

I am not using the grid’s own scrollbars as I find them slow on mobile devices with large grids. Web page scrolling is much smoother.

Regarding your comment “cellclick is raised on tap, drag happens on tap and move” – dragging and tapping are different gestures and I believe that all widgets should differentiate between the two if possible.

Hi Paul,

If you’re with single row selection mode, then use rowselect. Regarding the gesture – you’re not right. dragging includes tap + hold + moving your finger up, down, left or right.

Peter,

I can’t use rowselect as I need to know which column was clicked on. My click event handler is specific to the cell clicked on.

Re the grestures, I am talking about the conceptual difference between tapping and dragging gestures – the two are different concepts in the world of touch device usage. A tap is a quick press-and-release action. A drag is press-slide-release. It must be possible to detect the latter – e.g. if the user’s finger is in a different position on release, then do not fire the ‘click’ event.
