Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

[BrowsableAttribute(true)]
public int CornerRadius { get; set; }

public:
[BrowsableAttribute(true)]
property int CornerRadius {
    int get();
    void set(int value);
}

[<BrowsableAttribute(true)>]
member CornerRadius : int with get, set

<BrowsableAttribute(True)>
Public Property CornerRadius As Integer

Property Value

Type: System.Int32

An Integer representing the radius. The default is 0, or no radius.

Remarks

The minimum value of CornerRadius is 0. This results in a rectangle or square without rounded corners. The maximum value is the height or width (whichever is smaller) of the RectangleShape divided by two. For a square shape this will create a circle.

Examples

The following example changes the CornerRadius of a RectangleShape when the RectangleShape is clicked. This example requires that you have a RectangleShape named RectangleShape1 on a form.

private void rectangleShape1_Click(System.Object sender, System.EventArgs e)
{
    int max;
    // Calculate the maximum radius.
    max = Math.Min(rectangleShape1.Height, rectangleShape1.Width) / 2;
    // Check whether the maximum radius has been reached.
    if (rectangleShape1.CornerRadius == max)
    // Reset the radius to 0.
    {
        rectangleShape1.CornerRadius = 0;
    }
    else
    {
        // Increase the radius.
        rectangleShape1.CornerRadius = rectangleShape1.CornerRadius + 15;
    }
}

Private Sub RectangleShape1_Click(ByVal sender As System.Object,
 ByVal e As System.EventArgs) Handles RectangleShape1.Click
    Dim max As Integer
    ' Calculate the maximum radius.
    max = Math.Min(RectangleShape1.Height, RectangleShape1.Width) / 2
    ' Check whether the maximum radius has been reached.
    If RectangleShape1.CornerRadius = max Then
        ' Reset the radius to 0.
        RectangleShape1.CornerRadius = 0
    Else
        ' Increase the radius.
        RectangleShape1.CornerRadius =
          RectangleShape1.CornerRadius + 15
    End If
End Sub
