double10
Max

Limits the target, or logical start target, in pixels; a null value leaves the upper bound unrestricted.

double?null
Min

Prevents the target, or logical start target, from falling below this pixel value.

double0
Offset

Moves the resizer outward from its configured edge by the specified number of pixels. Negative values move it inward.

double0
Orientation

Possible values:Horizontal, Vertical

OrientationOrientation.Horizontal
Placement

Positions the resizer on the target edge. In coordinated mode, target order determines the resize direction.

ResizerTargetsnull
Thickness

double?null
Value

Supplies the controlled target size in pixels. In coordinated mode, this is the logical start-target size.

double?null
