How Draw Rectangle Gradient Brush?

[_Roman]

I want draw Rectangle use Gradient Brush.

        
protected override void OnRender(ChartControl chartControl, ChartScale chartScale) {
LinearGradientBrush linGrBrush = new LinearGradientBrush(System.Windows.Media.Color.FromArgb(255, 255, 0, 0),System.Windows.Media.Color.FromArgb(255, 0, 0, 255), new System.Windows.Point(0, 10),  new System.Windows.Point(200, 10));  
 RenderTarget.FillRectangle(new RectangleF(10, 10, 300, 300),SharpDX.Direct2D1.Brush( linGrBrush)); }

In line RenderTarget.FillRectangle(new RectangleF(10, 10, 300, 300), SharpDX.Direct2D1.Brush( linGrBrush)); the compiler generates an error.
How I can use Gradient Brush? How I can draw Rectangle with Gradient Brush?
Thank you.

Hello _Roman,
Thanks for your post.

It looks like you need to convert the LinearGradientBrush to be a SharpDX brush using ToDxBrush(). Something like the following snippet seemed to resolve the compile error on my end:

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
    LinearGradientBrush linGrBrush = new LinearGradientBrush(System.Windows.Media.Color.FromArgb(255, 255, 0, 0),System.Windows.Media.Color.FromArgb(255, 0, 0, 255), new System.Windows.Point(0, 10),  new System.Windows.Point(200, 10));
    SharpDX.Direct2D1.Brush dxBrush = linGrBrush.ToDxBrush(RenderTarget);
    RenderTarget.FillRectangle(new RectangleF(10, 10, 300, 300), dxBrush); 
}
