function set CornerRadius (value : int)

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 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

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;
    }
}
