By default, the Selectable property is True, so the user can select the layer if the cursor hovers it. The Selectable property specifies whether the layer's background is selectable. You can use the Grayscale property to show the entire layer in gray scale ( disable state). The Visible property specifies whether the layer's background is visible or hidden. The Picture / ExtraPicture property adds a picture on the layer's background. Use the Value property to specify a solid / EBN color to be applied on the layer's background.

The Selectable property of the Background object, affects all the pictures / colors being shown on the layer's background. In order to prevent selecting portions of the layer you can use any of the following properties:

• Selectable property of the LPicture object, returns or sets a value that indicates whether the picture is selectable.
• Selectable property of the LColor object, returns or sets a value that indicates whether the color is selectable.
