Move Group/layer

[Administrator]

Is there a way to move a layer or a layer in a page ?

Thanks Meera

But ir does not explain how to MOVE the layer.

It only sets it visible.

Thanks but it does explain how to programtically move the layer...

Correction:

The question should be read :
How to move a group/Layer (what is the best ?) in a view/model

Actually, i want my user to draw some parts (each one is invisible to the other) and then position the nodes(of the group or the layer) in a certain way on the page

Hi Paul,

Please refer the Diagram Samples/InDepth/NetworkFlowModel sample which demonstrates about how to use different layers ,to add nodes to the layers and make them as visible/invisible. Depending on the visible state of the layer the samples present in the layer are shown/hidden.

Please let me know if you have any questions.

Thanks,
Meera.

I think i found how to do it via the MoveCommand.
The question is how to get a INodeCollection of the nodes of a Layer

Hi Paul,

If your intention is to iterate through the nodes collection in the Layer , you can get it done by using the Layer.GetEnumerator() which returns an enumerator that can be used to iterate through the nodes in the given Layer according to their Z-order.

Add the following code snippet to the NetworkFlowModel sample in particular to the toolBar_ButtonClick Event code block.

if(e.Button.Tag.ToString() == "EtherNet")
{
Layer ethernet = this.diagram1.Model.Layers["EtherNet Layer"];
ethernet.Visible = !e.Button.Pushed;
this.SetConnectingLinksVisibility(ethernet);

//Iterating Layer nodes

ArrayList nodesinZOrder = new ArrayList();
int count =0;
IEnumerator inodes = ethernet.GetEnumerator();
while(inodes.MoveNext())
{
if(inodes.Current is Symbol)
{
Symbol newsymbol = inodes.Current as Symbol;
MessageBox.Show(newsymbol.Name.ToString(),ethernet.Name.ToString());
nodesinZOrder.Add(inodes.Current);
}
}
}

Please let me know if you have any further queries regarding this.
