Method UpdateSize
UpdateSize()
Causes any pending sizing of the sash and child panes to take place immediately.
public virtual void UpdateSize()
Remarks
Such resizing normally takes place in idle time, in order to wait for layout to be completed. However, this can cause unacceptable flicker as the panes are resized after the control has been shown. To work around this, you can perform control layout (for example by sending a size event to the parent control), and then call this function, before showing the top-level window.
