We have added a new KB article about how to hide expand (+) sign button in certain node that has no child nodes during WebTreeView’s load-on-demand operation.
By default, the expand button will be rendered along with the child nodes regardless whether a node has a child. This behavior sometimes confuses the user as they cannot see which node has child and vice versa.
To perform the above scenario, you can simply add 2 lines of code in InitializeNode server side event, like following:
protected void WebTreeView1_InitializeNode(object sender, WebTreeViewNodeEventArgs e)
if (e.Node.Nodes.Count == 0)
e.Node.ChildNodeExpandable = false;
When you run the project, it will look like following:
The sample is available to be downloaded in here.
