Hello, we want to add a tree view control to our simple web GIS system to allow us to better display the available layers to the user. The current version is here:

PlanMaps

Your tree view control looks good and seems to offer what we need so I downloaded your demo version and have been trying it out, but am having some problems adding sub item tree nodes programatically. I don't want to bind the tree view to a dataset, but add each item from code. I would have a set of Items say: Planning, Environment, Public Space and under each of these a number of sub items for each layer with check boxes so layers can be turned on and off. I would be grateful for confirmation that this is possible with your control and some pointers to how it would be done before I take it further and suggest buying your tools.

many thanks

Bruce

Yes. Just do something like this:

Code: C# 
//Create a root node
EO.Web.TreeNode node = new EO.Web.TreeNode("Planning");
TreeView1.Nodes.Add(node);

//Create a child node
EO.Web.TreeNode childNode = new EO.Web.TreeNode("Planning Layer1");
TreeView1.Nodes[0].ChildNodes.Add(childNode);

....


Thanks
