How to sort child nodes of a node.

[Kipp]

How can I sort the child nodes of a particular node?

Hi Kipp,

Thank you for writing.

You can do that by using custom sorting and creating a custom node comparer. You can use the following code snippet:

public class TreeViewComparer : IComparer<RadTreeNode>
{
    public int Compare(RadTreeNode x, RadTreeNode y)
    {
        if (x.Parent != null && x.Parent == y.Parent && x.Parent.Name == "YourNode")
        {
            return Comparer<string>.Default.Compare(x.Name, y.Name);
        }

        return 0;
    }
}

this.radTreeView1.TreeViewElement.SortOrder = SortOrder.Ascending;
this.radTreeView1.TreeViewElement.Comparer = new TreeViewComparer();

I hope this helps.

Kind regards,
