ShapedForm working as expected?

Hi Martin,

Thank you for the provided details.

I have tested your approach and I am assuming that the RoundRectShape shape is applied to the Shape property of the form. Removing the radius of some of the corners is controlled from the BottomLeftRounded, TopLeftRounded, BottomRightRounded, and TopRightRounded. After testing this the border-radius is removed however, the ShapeForm content area remains clipped. That is why you observe this clipping and it looks like the mentioned above properties are not respected. I can confirm that this behavior is unexpected and therefore I have logged it on your behalf in our Feedback Portal where you can track the progress of the item. As a workaround, you can override the IsRectangularShape() method of the ShapedForm and return false. I have updated your Telerik Points for bringing this behavior to our attention.

public partial class Form1 : Telerik.WinControls.UI.ShapedForm
{
    public Form1()
    {
        InitializeComponent();
        new RadControlSpyForm().Show();
        this.FormBorderStyle = FormBorderStyle.FixedToolWindow;
        this.Load += Form1_Load;

    }
    protected override bool IsRectangularShape(ref int radius)
    {
        return false;
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.BorderColor = Color.Red;
        this.BorderWidth = 2;
        RoundRectShape roundRectShape = new RoundRectShape();
        roundRectShape.Radius = 30;
        roundRectShape.BottomRightRounded = false;
        roundRectShape.TopLeftRounded = false;
        this.Shape = roundRectShape;
    }
}

As for your third question you can set the FormBorderStyle property to FormBorderStyle.FixedToolWindow. This way the ShapeForm won't be draggable and the maximize state with mouse double-click will be disabled.
