Hi,

Do you mean you are using the TreeViewNode class? It can display only one column, and the number of rows depends on the number of items in TreeViewNode.RootItems and their children. If you need to show more columns of data, you could use TableNodes. For best results arranging both kinds of nodes, use LayeredLayout with Orientation set to Horizontal.

I hope that helps,
Stoyan

hi,

thank you for reply.

sorry its mindfusion diagramming showing table nodes with joinlinks

just boiling my head to do it from morning.

but how can i specify it can i have any example for layerd layout usage can i add table nodes to different layers at run time.

my requirement is adding tablenode to different layer depends on join sequesnce

means join sequence of tablenode
1 means in column 1
2 means in column 2
3 in column 3 so on ..up to 10 columns

each columns can have no of table nodes

please give me sample if possible

thanks
Embarrassed

Hi,

Set LayeredLayout.EnableCustomLayers = true and assign your join number to node.LayoutTraits[LayeredLayoutTraits.Layer]. This won't work if you have links between tables on the same layer. If you need that, try using a vertical SwimlaneLayout instead, where the join number is assigned to LayoutTraits[SwimlaneLayoutTraits.Lane]. Note that for both layout classes the Layer/Lane indices are zero-based.

I hope that helps,
Stoyan

Try setting IgnoreLayout = true on such links. Then you will have to implement some additional processing for them after calling Arrange(), to set their control points appropriately to avoid crossing the tables.

Hi,

After creating and arranging the previous nodes, call GetContentBounds() to find the bounding rectangle for all content in the diagram. Then create the container at (10, contentRect.Bottom + some_offset).

I hope that helps,

Hi,

You could place it at Y = diagram.Bounds.Bottom - container.Bounds.Height.

I hope that helps,

hi,

container = diagram1.Factory.CreateContainerNode(0,diagram1.Bounds.Bottom-container.bounds.h
eight,500,20);

Hi,

Call container.UpdateBounds() after adding its child nodes.

I hope that helps,
