any demo showing use of DetailModel?
« on: June 15, 2015, 03:40:18 am »
I'm new to the Pro version and I'd like to see how to use DetailModel, VirtualX, VirtualY, etc. if possible.

Following are the demos for usage of detailModel.

1. http://paramquery.com/pro/demos/nesting

2. http://paramquery.com/pro/demos/detail

virtualX: true enables virtual rendering for columns and virtualY: true enables virtual rendering of rows.

These are the demos for virtualX and virtualY

Hello,

Given that use of virtualX and VirtualY improves rendering speeds for large number or rows and columns, why are these options not defaulted to true?

Under what circumstances is it better to have virtualX/virtualY set to false?

virtualX & virtualY: false are better when

1. Swipe gesture is required.

virtualY: false is better when

1. row height is more than height of viewport.

virtualX: false is better when

1. column width is more than width of viewport.

2. Column grouping is required and version < 3.0.0
