I do a drag drop image on m_chart as shown below
Code: Select all
private void m_chart_DragDrop(object sender, DragEventArgs e)
{
PictureBox pb = new PictureBox();
pb.Image = (Bitmap)e.Data.GetData(typeof(Bitmap));
pb.Size = pictureBox1.Size;
pb.SizeMode = pictureBox1.SizeMode;
pb.Location = this.PointToClient(new Point(e.X - pb.Width / 2, e.Y - pb.Height / 2));
m_chart.Controls.Add(pb);
}
and the result is like this
- result of drag and drop image on m_chart
- drag and drop image on m_chart.JPG (28.72 KiB) Viewed 19637 times
After the picture box has been added to m_chart, I would like to drag and drop the "added picture box" from its existing location to another location of the m_chart.
But here gives me a pause. How to create a mouse event for the "added control" in m_chart ? Any idea?
Regards,
JH

Hi Jhyap,
why not adding AnnotationXY object in Annotations collection, and setting a bitmap fill into it. That way, you don't need to use a PictureBox. And annotations support moving, scaling, rotating etc. with mouse.

Hi Pasi,
When I click on the annotation, the center marker is appeared (the dim grey circle marker as shown below). How can I remove or set the center marker to be invisible?

I am using the annotaion.MouseOverOn and annotation.MouseOverOff event, hence, I cannot set the annotation.MouseInteraction to false.
below is my code for setting the annotation
Code: Select all
private void m_chart_DragDrop(object sender, DragEventArgs e)
{
m_chart.BeginUpdate();
anno = new AnnotationXY(m_chart.ViewXY, m_chart.ViewXY.XAxes[0], m_chart.ViewXY.YAxes[0]);
anno.Fill.Bitmap.Image = (Bitmap)e.Data.GetData(typeof(Bitmap));
anno.Fill.Bitmap.Layout = BitmapFillLayout.Stretch;
anno.Fill.Style = RectFillStyle.Bitmap;
anno.Style = AnnotationStyle.Ellipse;
anno.Sizing = AnnotationXYSizing.ScreenCoordinates;
anno.SizeScreenCoords.Width = pictureBox1.Size.Width;
anno.SizeScreenCoords.Height = pictureBox1.Size.Height;
anno.LocationCoordinateSystem = CoordinateSystem.ScreenCoordinates;
anno.Shadow.Visible = false;
anno.BorderLineStyle.Width = 1.5f;
anno.MoveByMouse = false;
anno.ResizeByMouse = false;
anno.MouseHighlight = MouseOverHighlight.None;
anno.RotateByMouse = false;
anno.Text = annoText;
anno.TextStyle.Visible = false;
Point a = this.PointToClient(new Point(e.X - (int)anno.SizeScreenCoords.Width / 2, e.Y - (int)anno.SizeScreenCoords.Height / 2));
anno.LocationScreenCoords.X = a.X;
anno.LocationScreenCoords.Y = a.Y;
m_chart.ViewXY.Annotations.Add(anno);
anno.MouseOverOn += new MouseEventHandler(anno_MouseOverOn);
anno.MouseOverOff += new MouseEventHandler(anno_MouseOverOff);
m_chart.EndUpdate();
}

This answer seems to be delayed because of expired subscription.
set anno.AnchorAdjustByMouse = false;
