Solution 1

It looks like the type of the DataPointStyle property is Style and, you try to set to it a value of type Color...

Style style = new Style(typeof(DataPoint));

this.Series1.DataPointStyle = style;

Maybe you set the Background property in the element's XAML. If so, it overrides the style's value.

thanx shmuel,
yes, i am setting in background xaml, bt again i want to change from code? is it possible?

Why changing it from the code? It isn't the best practice. Maybe you want to use binding?

actualy, i am giving option to user to change it,,,

I removed background from XAML and tried, stile it not working.
