Hi,
I have a scrollable view which contains a picturebox.
I need to get the location of the top let hand corner of the view so I
can draw an icon.
When the picturebox is scrolled vertically I need the icon to remain in
the top left hand corner of the view.
At the moment whenever I scroll the picturebox down, the icon gets
hidden.
Thanks in advance.
private void pictureBox1_Paint(object sender,
System.Windows.Forms.PaintEventArgs e)
{
// Need to get the correct location otherwise the
rectangle will disappear when
// the picture is scrolled up
Rectangle boundingRect = new Rectangle(0, 0, 150, 50);
LinearGradientBrush myLinearGradientBrush = new LinearGradientBrush(
boundingRect,
Color.AliceBlue,
Color.Silver,
LinearGradientMode.ForwardDiagonal);
e.Graphics.FillRectangle(myLinearGradientBrush, boundingRect);
Rectangle rc = boundingRect;
rc.Inflate(-1,-1);
e.Graphics.DrawRectangle(new Pen(SystemColors.Highlight), rc);
} 3 2296

You need calculate how much height/width you scrolled (X, Y), and then
apply this offset when you do the actual drawing.

I am using the autoscroll feature of the view. How can I get a handle
to the scrollbar in that case?

Control has a property called Handle, is this what you look for.
Also, ScrollableControl should have AutoScrollPosition property which
you can tell how much you have scrolled. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
