I haven't used autscale yet, but I believe autoscale only works with views added in designer

You must calculate a scale factor on your own and apply it to all the coordinates.

Hi Klaus,
Please demo how to calculate a scale factor. I don't know. Why is AutoScaleRate(0.9) or AutoScaleRate(0.5) ? Where are them come from?

For AutoScaleRate look here.
Calculating a scale factor for canvas depends on what you want to do.
If you want to adapt it to AutoScale you can calculate the scale factor with the equations given in the link above.

AutoScaleRate(0.9) or AutoScaleRate(0.5)? Where are them come from?

From testing with different Rate values.
Rate = 0 no scaling
Rate = 1 almost similar as %x / %y scaling.

Best regards.

The problem with me is I am having one device for test . I realize the problem when an customer brings a new device with different screen size (eg : 10 inch tablet ) . Then I have to re design the every screen ( My app having 12 screens) . When ever I adjust the layout for a screen size , In another screen size it does not look accordingly . My only request is , Please share an example with designer views and coded views (like canvas ) for the autoscale concept .:BangHead:

It would be much easier if you posted one of your examples.
And I have a look at it.
