change of size of PictureBox? (error in code, or in .NET2.0?)

[dorwin]

Hi, I have a simple project in WinForms (C# Express) .NET 2.0: vo form I have inserted panel (panel1) and in panel there is PictureBox1 Panel1 has property Dock = Fill PictureBox1 has property Dock = Top on Resize event for picturebox I have: /*----------------------------------------------------------------------*/ 1 private void pictureBox1_Resize(object sender, EventArgs e) 2 { 3 Image newImg = new Bitmap(panel1.Width ,panel1.Height ); 4 if (PictureBox1 != null) 5 { 6 if (PictureBox1.Image != null) 7 { 8 PictureBox1.Image.Dispose(); 9 PictureBox1.Image = null; 10 } 11 PictureBox1.Image = newImg; 12 } 13 } /*----------------------------------------------------------------------*/ After maximalisation of forrm has PictureBox unchanged size, although there is Dock property set to "Top". When I comment line #11, everything works fine. Why? I need to create image in PictureBox dinamically after each resizing of picturebox. However size of picturebox is not affected, and the worse it do something bad with Dock feature.. In .NET 1.1. it worked perfectly, however in .NET 2.0 it doesn't. projekt is saved here: http://www.tekl.com/testform1.zip ( has 36kb). Thank you for any help. I don't know, what to do.

try changing pictureBox1.SizeMode property to AutoSize. While you use SizeMode=Normal, pictureBox always keeps it's starting size, unless you tell it to change it. AutoSize mode will resize pictureBox to fully show image, each time image changes. Robin Panther http://www.robinland.com

:) thank You so much! this was the reason.. SizeMode is new property in .NET 2.0 :)
