I have done through autoscale function tutorial.it works fine for controlling the view position but i am only facing problem to change fontsize dynamically eg: listview etc.pls advise how to resolve this problem.
You should read chapter 8.10.3 AutoScale more advanced examples in the Beginner's Guide.
In the SourceCode/AutoScaleExamples folder you have a project called AutoScaleExample4 containing a Scale code module which allows autoscaling in the code including ListView text size.
