I using dxlc:LayoutControl and a dxlc:LayoutGroup within it. I have managed to remove groupbox border by writing following markup .
<Style x:Key="layoutGroupBoxStyle" TargetType="dxlc:GroupBox">
<Setter Property="BorderThickness" Value="0" />
</Style>
but GroupBox Header's bottom border is still visible. how can I remove that bottom border of GroupBox Header ??
To remove this line, it is necessary to modify templates in our themes
