Disable Expand/Collapse Client Side

[Christian]

Hi,

I am populating my TreeView using TreeNodeExplandMode.WebService, which works fine. But when i populate a node that dosen't have any childnode i would like to disable Expand/Collapse, so the expand icon dosen't appear.

How do i achieve this? Should this be done on the RadTreeNodeData object or should i do this Client Side?

Best Regards,
Christian

Hi Christian,

If you don't set the ExpandMode property of the RadTreeNodeData object the node will not display the expand icon. Here is an excerpt from your web service example
        foreach (DataRow row in productCategories.Rows)
        {
            RadTreeNodeData itemData = new RadTreeNodeData();
            itemData.Text = row["Title"].ToString();
            itemData.Value = row["CategoryId"].ToString();

            if (Convert.ToInt32(row["ChildrenCount"]) > 0)
            {
                itemData.ExpandMode = TreeNodeExpandMode.WebService;
            }

            result.Add(itemData);
        }
