abstract GetPreferredSize : proposedSize:Size -> Size override GetPreferredSize : proposedSize:Size -> Size
- Type: System.Drawing.Size
The custom-sized area for a control.
The behavior of differs by control. The LayoutEngine might be unable to assign the returned size to the control. You can return a size larger than the constraints indicated in the proposedSize parameter, but proposedSize should decrease as the constraint decreases. For example, GetPreferredSize(new Size(100, 0)) should not be wider than GetPreferredSize(new Size(200, 0)). The exception is a proposedSize of 0 or Size.Empty, which are defined as unconstrained.
