How to change color of individual chart elements color in powerpoint? RRS feed

  • Question

  • How to get element (shape ) in chart that is selected (clicked ) by mouse by user .I want to change color of selected element ,but every time what i am getting in shapeRange is "placeholder".

    last thing what i tried is 

    ColorStyle colorstyle2 = MyAddin.AddinModule.CurrentInstance.SelectedColorStyle;
    int setColor = ColorTranslator.ToOle(System.Drawing.Color.FromArgb(colorstyle2.R, colorstyle2.G, colorstyle2.B));
    int position = app.ActiveWindow.Selection.ShapeRange.ZOrderPosition;
    Slide slide2 = (Slide)app.ActiveWindow.View.Slide;// SELECTS CHART FROM SHAPE RANGE AS SELECTION HAS SHAPERANGE not shape
    powerPoint.Shape s = slide2.Shapes[position];
    if (s.HasChart==MsoTriState.msoTrue)
    {
        object cht = s.GetType().InvokeMember("Chart", BindingFlags.GetProperty, null, (object)s, null);
        object chtFormat = cht.GetType().InvokeMember("Format", BindingFlags.GetProperty, null, (object)cht, null);
        object chtFill = cht.GetType().InvokeMember("Fill", BindingFlags.GetProperty, null, (object)chtFormat, null);
        object chtBackcolor = chtFill.GetType().InvokeMember("Backcolor", BindingFlags.GetProperty, null, (object)chtFill, null);
        object[] args = { setColor };//also used {0} here
        object chtRGB = chtBackcolor.GetType().InvokeMember("RGB", BindingFlags.SetProperty, null, (object)chtBackcolor, args);
    }

    But it does nothing !
