TrackControl using Markup

Hi,

I have been playing around with the Codejock MarkupPad to create a ProgressBar that can be inserted into the Block.Caption within the TrackControl. I have managed to get this to work however I am now stuck because I can't seem to get the length of the Blocks at runtime, the TrackControl is zoomable so therefore the Blocks change length as the control is zoomed.

So does anyone know of a way to get a Blocks length when the TrackControl is zoomed in and out?

I am setting the ProgressBar width as Block.length but this is then auto zoomed to the best fit by default therefore the width is wrong and unfortunately the Markup won't allow Width='100%'

Any ideas are appreciated!!!

I had tried the Width='Auto' but it didn't work in the approach I had taken, which was using the <Canvas> element.

I have instead opted for a <Grid> element as this allows you to set the <ColumnDefinition Width='100*'></ColumnDefinition> 100* being 100%

This has allowed me to get the ProgressBar within the TrackBlock resizing correctly.

See screenshot below:


Note: There is a slight discrepancy in the ProgressBar value when zooming. But it's as near as damnit! I will see if I can tighten this up before I upload this version.

After some tweaking of the aspect ratio code I have got it working quite well, if anyone can improve upon the zoom ratio code then please feel free to do so.
