So, to follow up on my previous article I decided that there was even more that could be done to reclaiming dead space on MMS121.
Before we go too far, it’s worth pointing out that our MMS121 is modified to add Sorting Order 9, this adds some extra TextBoxes and labels down the bottom.
There are a lot of controls that are on the screen that are of no use or interest, hiding the unneeded controls doesn’t actually reclaim any space until we start moving controls around. So to that end.
Here’s what we have to work with.
And after some jscript magic, this is what we end up with.
There is still some space that can be reclaimed down the bottom but it creates some issues with our forklifts.
Now there was a lot of experimentation that went in to this. The hiding of the controls and the moving them was easy, not to mention resizing the ListView, maybe few hours of mucking around. The kicker was handling the ability to resize the Window and keep everything visible, stretched and sized properly – it’s wasn’t strictly needed for our purposes but I was curious.
The second issue was when the Sorting Order is changed or the user hits Refresh then it redraws the controls – all our added controls and changes effectively get reset see https://potatoit.wordpress.com/2010/12/23/where-did-my-control-go/ for some more detail.
We also manually change the visibility (yes, I know we don’t have to do it programmatically).
Other points of interest –
Controller.Host.HostTitle shows us the title of the Window.
Controller.RenderEngine.InquiryType is the current Sort Order
This can probably be slimmed down even more as some of the code is probably redundant as I continue to refine.
