Hello,

WinFormResizer assumes that the "dynamicValue" you specify for height is proportional to the current Form's size unless otherwise told.

For example, if you specify a height of 10 while the Form is maximized, restoring the Form to its normal size will cause the problems you are seeing.

The way to change a PictureBox control's height "manually" at run time is to modify it's InitialSize property:


C#:

// Get a reference to the PictureBox's current InitialSize
Size szInitial = winFormResizer1.Extenders[pictureBox1].ExtendedLayout.InitialSize;


// Set the PictureBox's new height by specifying its new size based on its current initial width and
// new height.
winFormResizer1.Extenders[pictureBox1].ExtendedLayout.InitialSize = new Size(szInitial.Width, NewHeight);


// Update the Target (Form)
winFormResizer1.UpdateTarget();


VB.NET:

' Get a reference to the PictureBox's current InitialSize
Dim szInitial As Size = winFormResizer1.Extenders(pictureBox1).ExtendedLayout.InitialSize


' Set the PictureBox's new height by specifying its new size based on its current initial width and
' new height.
winFormResizer1.Extenders(pictureBox1).ExtendedLayout.InitialSize = new Size(szInitial.Width, NewHeight)


' Update the Target (Form)
winFormResizer1.UpdateTarget()

This link (DnxPictureBoxes.zip) points to a simple VS 2005 (C#) example solution containing 10 picture box controls that have their Sizes manually modified at run time.
