Visibility Not Working For Insert

[slingblade]

Hi,

I have noticed that setting the visibility property to false does not change Insert's visibility, it will change the visibility state of lines.

I am using the FAQ_Demo.Net sample and in the mousedown event I am finding the layer of the entity selected and then I iterate over all the entities in the drawing and if it is on the same layer as the selected entity then I set the visibility property to false.

Can you help me understand why this doesn't work for Inserts but it does work for lines?

I will email you the dwg...

Code: Select all

        private void cadPictBox_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
        {
            if (this.cadImage == null)
                return;
            
            if (e.Button == MouseButtons.Left)
            {
                if ((this.cadImage.SelectionMode == SelectionEntityMode.Enabled) && useSelectEntity)
                {                    
                    if (cadImage.Select(e.X, e.Y))
                    {
                        CADEntity entity = cadImage.SelectExt(e.X, e.Y, true, false);

                        string layerName = entity.Layer.Name;

                        foreach (CADEntity ent in cadImage.Converter.Entities )
                        {
                            if (ent.Layer.Name == layerName)
                            {
                                ent.Visibility = false;
                            }

                        }

                        cadPictBox.Invalidate(cadImage.GetSelectEntityRegion(this.cadPictBox.ClientRectangle));

                    }
                }
            }
            else
            {
                if ((e.Button == MouseButtons.Right) || (e.Button == MouseButtons.Middle))
                {                    
                    cX = e.X;
                    cY = e.Y;
                    detRMouseDown = true;
                    return;
                }
            }
            if ((!this.clipRectangle.Enabled) && (this.cadImage != null) && (!this.Orb3D.Visible))
                this.clipRectangle.EnableRect(RectangleType.Zooming, new Rectangle(e.X, e.Y, 0, 0));
        }

Hi,

I found a work around to make the insert's invisible.

I iterated all of the entities in the block collection for the insert and individually set them to visibility = false and that seems to work.

In a perfect would It would of course be great to not have to do that and if you set the parent control visibility = false then all of the children controls should follow suit and also set their visibility property. This would be more logical and I wouldn't have to spend hours trying different things to get this to work.

Hello.
The code is correct and the Visibility property set to false, but insert entity still visible after invalidating. Thank you for finding work around. You're correct - it's not a best way. We will consider the problem and let you know when the solution is ready.

Alexander.
