Hi Stoyo,

I need to create some specific shape nodes ( treated as Grouping nodes like container).

These group nodes are just for showing border or grouping of multiple items. By setting transparnt color I am able to show grouping of specific nodes under one color.

In some cases it is possible that my top node is partially inside the group node and partially outside. With such case I see the border of group node in the node which is placed above it.

Is it possible that the "partial" border of node should not be shown when another node is placed  above it but not completely(partially in and paritally out).

Hi Stoyo

I want to implement something like following


In this image, the node with text "Test6111" displays half bottom part in different color. Expected is the color which is visible in Upper Top part should be displayed.

Similarly, I am not able to click on bottom part of "Test6111" or on nodes "Test211" and "Test111". I need all small nodes should use the yellow color which is outside the group node.

Will you provide me a code snipet for same.

Regards
Rajesh

Hi Stoyo

Nope, setting ZIndex = 0 doesn't work. Its behavior is same as older one.

For your information, the 3 small nodes are created in load function and the group node is created using the default behaviour and then its color and zindex is changed in on node creation event.

Hi Stoyo

No, its normal node like any other node and created by default diagram behavior with mouse movement.

I checked with container node and when I add my child nodes in container nodes childeren collection I am able to click on the child nodes and the behavior which is expected when border is shown to group node is not visible when node is partially in group and partially out of group.

In my problem, I need same behavior using normal nodes.
In my application all nodes are normal node. The group node user might want to show below all nodes to just visually indicate the group of nodes ( in reality they are not child of any nodes) . Addtion of this group node is depend on user choice and it may be possible that one node needs to be shown shared by more than one container.

With container node, on node creation or resizing i need to find out which node needs to be added in current container. I don't want to do this for performance reason.

------------------------------------------------------------------Update for your infomration :
For container node i think adding childern is not required.

Following code doesn't give me expected behavior



foreach (MyShape shape1 in list)


{


ShapeNode shape = new ShapeNode(this);


shape.Brush = new SolidColorBrush(Color.FromArgb(255, 255, 255, 45));


//shape.Stroke = new SolidColorBrush(Color.FromArgb(0, 0, 0, 0));


shape.Text = shape1.Name;


//c.Children.Add(shape);


this.Nodes.Add(shape);


}

[b]

ContainerNode c = new ContainerNode(this);


c.Text = "123";


c.Brush = new SolidColorBrush(Color.FromArgb(10, 128, 0, 145));


//c.Stroke = new SolidColorBrush(Color.FromArgb(0, 0, 0, 0));


c.ZIndex = 0;


this.Nodes.Add(c);[/b]

But if I write the bold code before the for loop i get expected behavior. In my case the container needs to be created later on demand by the user.

Hi Stoyo

It seems there is some issue with
e.Node.ZIndex = 0;

Because I don't think second call is required. I commented out above statement and with
Canvas.SetZIndex(e.Node,0) it is working as expected.

Will you arrage to fix this issue.

Hi Rajesh,

Try setting diagram.HitTestPriority = ZOrder.

Hi,

Set node.ZIndex too after calling diagram.Nodes.Add. Z order operations do not have any effect before that.
