Hi,

There's no databinding support implemented right now. You can implement that yourself like this:

- iterate the dataset for the nodes table and create a box for each node using CreateBox; save in a hash table the mapping between the node ID and the Box object

- iterate the links table and create the links between boxes using CreateArrow; use the hash table to find the boxes that you should use as CreateArrow parameters from the nodes IDs

- create a TreeLayout object and call its Arrange method

HTH

p.s. We have a general purpose binding module implemented in our Planner.NET component and we can easily reuse that in NetDiagram, but we will leave that for version 1.1

Hi,

You could build a tree diagram from database records as shown below:

[code]
Hashtable childToParent = new Hashtable();

SqlCommand cmd = new SqlCommand();
cmd.Connection = conn1;
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT * FROM dbo.TreeNodes";
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
     Box node = fc.CreateBox(0, 0, 40, 30);

     int nodeID = reader.GetInt32(0);
     node.Text = reader.GetString(1);
     int parentID = reader.GetInt32(2);

     node.Tag = nodeID;
     childToParent[nodeID] = parentID;
}

foreach (Box b in fc.Boxes)
{
     if  (!childToParent.ContainsKey(b.Tag))
           continue;

     fc.CreateArrow(
           fc.FindBox(childToParent[b.Tag]), b);
}

TreeLayout tl = new TreeLayout();
tl.Arrange(fc);

[/code]

I hope that helps,

Isn't this what you get with the Netdiagram's ImageMap mode and a TreeLayout?
