In the above image, the height of the control is not calculated correctly in the Windows 11 theme. In addition, the Details arrow button overlaps the text.
Hello Peter,
Thank you for reporting this behavior. As a workaround, we can increase the height of the control and offset the arrow image.
RadMessageBox.Instance.Shown += Instance_Shown;
private void Instance_Shown(object sender, EventArgs e)
{
RadMessageBox.Instance.Height += TelerikDpiHelper.ScaleInt(10, RadMessageBox.Instance.RootElement.DpiScaleFactor);
(RadMessageBox.Instance.Controls[5] as MessageBoxDetailsButton).Arrow.PositionOffset = new SizeF(-17,0);
}
