jQuery/JS Common - Object Structures - positionConfig - boundaryOffset

This option is used to resolve collisions. If the specified offset from the specified target leads to a collision with the window's boundary, the boundaryOffset value is used to position the element near the place of collision.

This option accepts an object containing the x and y fields which specify horizontal and vertical offset respectively, or a string in the following format: "5 -10", where the first number is a horizontal offset and the second number is a vertical offset in pixels.

When you configure a widget as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control, this option accepts two values of the double type.

@(Html.DevExtreme().WidgetName()
    .Position(p => p
        .BoundaryOffset(5, -10)
    )
)

@(Html.DevExtreme().WidgetName() _
    .Position(Sub(p)
        p.BoundaryOffset(5, -10)
    End Sub)
)
