                        <ScaleTransform/>

                </ed:RegularPolygon.RenderTransform>
            </ed:RegularPolygon>            
        </Grid>
    </Viewbox>
</UserControl>

Answer 1

There are a number of ways to set the dimensions for a particular control. Hard coding exact Width and Height properties is the least recommended. Instead of that, you could try using the MinHeight, MaxHeight, MinWidth and/or MaxWidth properties that all controls have.

Another alternative is to set some restrictions using the ColumnDefinitions or WidthDefinitions of a parent Grid if the control resides in one.
