Hi Stoyo

How one can move a node to back and front ?

Is their any functions available like SendToBack and BringToFront ? If they are not availble which release will support these functions ?

I know, by changing the Z-index one can bring the node to above another node .. but how to decide which Z-index value should be assinged.

Hi Stoyo

In my observation, I found that when I set Z-Index = 0 for multiple items ( based on some condition) then newly added item get z-index value set to the position in the collection.

For eq. If I set Z-Index = 0 for first 5 nodes added in diagram, then 6th node added in the collection will get the Z-index value = 5.

When Z-Index order is for multiple items are same same then I think it considers the position in the collection to control the display (FYI : No item is child of any container item )

In above situation, I can't implement the suggestion proposed in you reply.

How I can do resolve this ?

When the ZLevelUp, ZLevelDown and ZTop, ZBottom function available in silverlight version ?

Hi Stoyo

I made one sample. Please find the sample on following url-
https://cid-2b9bf77533900b84.skydrive.live.com/self.aspx/.Public/Copy%20of%20Anc...

In this sample, on start up few nodes are created. You need to change their position slightly to make the look proper.

On the right side, there are 3 button -
1. Create new node in diagram control.
2. Create new node in first container.
3. Change zindex of selected node to 0 to move the item back.

Pressing button 1 & 2 new nodes gets created and you need to re-position them properly.

Now either selecting the newly created node or the nodes which are displayed on startup (which are in container) and pressing the 3rd button changes the Z-Index of the node and the node is moved back.

With node which is on main diagram this works as expected. But with nodes which are in container node, the expected thing is that Z-Index should get applied within container.

Can you help me in achiving this.

Hi Stoyo

Thanks. With container it is works. Now new issue with this is that ...

If i send one node to "Back" , result in another node above that node but this new node which is in front can not be send to back ...

As you said, all other nodes Z-index gets changed I guess that is not working correctly.

Hi,

It works fine with the latest version I have. Could you try it with this build we uploaded for you last week -
https://mindfusion.eu/_beta/diaglite14_shapegeom.zip

If you still have this problem, please email a sample project showing it to support@mindfusion.eu.

Hi Rajesh,

Probably it was built on a different system and got a different number from the compiler there.

Hi Stoyo

What is solution for my 2nd question -

In the sample, I mailed to you after re-arranging the nodes properly, I see that "Node2" and "Container2" are child of "Container1".

Node2 has index = 3 and Container1's index is 1. Trying to bring the "Container1" in front using "BringToFront" implementation in the sample, container2 comes front and "Node2" is send behind but this results in "Node1" which is child of "Container2" get behind the container2.

Hi Stoyo

I have similar code

DiagramNode node = this.diagram.Selection.Items[0] as DiagramNode;
if (node.Container != null)
{
int maxIndex = 0;
foreach (DiagramNode child in node.Container.Children)
{
maxIndex = Math.Max(maxIndex, child.ZIndex);
}
node.ZIndex = maxIndex;
}
else
{
node.ZIndex = this.diagram.Nodes.Count - 1;
}

Even with your code, I have same problem.
The container which is bring front, its childs are set to behind that container.
