Hi there!
I have a problem. My project have form with Panel control, which contain PictureBoxes. These PictureBoxes are created dynamically. I need to make ability to select PictureBoxes in standard way like in Windows Explorer: user hold the left mouse button and select a rectangular area. All PictureBoxes are caught in the area, will be selected.
The problem is I cannot draw a rectangle over the PictureBox, because it is included in a Panel container. I tried to solve the problem in two ways:
1) I put a transparent control over the Panel and draw a rectangle on it.
2) I use the drawing of a reversible frame on the ControlPaint.DrawReversibleFrame form.
The first method did not help me because if Panel has AutoScroll I was not able to select PictureBoxes outside the visible part of the Panel.
In the second method I found the sample code in MSDN. But the example code does not define the child elements of the parent Panel container, when the user draw a rectangle above the one.
Could you tell me please how to draw a rectangle above the child controls of the container and then to select the controls covered by the rectangle? Perhaps is there another way to solve this problem?
I would be glad of any information!
