i want give minimum , maximum values considering minimum values negative rather being zero.

**

how can balance slider 1 can slide left or right position , center default providing them horizontal fill on both sides?

a control template don't seems solution.

try setting maximum="1" minimum="-1" value="0" when using slider case

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
