[Solved] CustomGridLine ElementStyle in code behind

[Michael]

Hy Telerik,

is it possible to set the ElementStyle from an CustomGridLine with an new style in Code behind.

I wana do something like this in code behind:

<Style x:Key="CustomGridLineCursorX3" TargetType="Line">
    <Setter Property="StrokeDashArray" Value="1" />
</Style>

this.GridLineCursorX7test = new CustomGridLine()
 {
    Stroke = new SolidColorBrush(Colors.Blue),
    StrokeThickness = 2,
    ElementStyle = this.Resources["CustomGridLineCursorX3"] as Style
    XIntercept = 2500
};

I try it with that code:

DoubleCollection dc = new DoubleCollection();
dc.Add(1.2);

Style style2 = new Style(typeof(System.Windows.Shapes.Line));
style2.Setters.Add(new Setter(System.Windows.Shapes.Line.VisibilityProperty, System.Windows.Visibility.Collapsed));
style2.Setters.Add(new Setter(System.Windows.Shapes.Line.StrokeDashArrayProperty, dc));


this.GridLineCursorX7test = new CustomGridLine()
{
    Stroke = new SolidColorBrush(Colors.Blue),
    StrokeThickness = 2,
    ElementStyle = style2,
    XIntercept = 2500
};
xChartArea.Annotations.Add(this.GridLineCursorX7test);

I know that the style works, because of the "VisibilityProperty".
I can set the VisibilityProperty to Visible and the CustomGridLine is visible.
And i can set it to Collapsed and the CustomGridLine is hidden.

Can you help me please!

Hello Michael,

 Unfortunately this is easily reproducible bug of the Framework (as stated here) and you can use the approach suggested in this blogpost to work-around it.

All the best,
