示例1: CustomizedTreeView
public class CustomizedTreeView : TreeView
{
public CustomizedTreeView()
{
// Customize the TreeView control by setting various properties.
BackColor = System.Drawing.Color.CadetBlue;
FullRowSelect = true;
HotTracking = true;
Indent = 34;
ShowPlusMinus = false;
// The ShowLines property must be false for the FullRowSelect
// property to work.
ShowLines = false;
}
protected override void OnAfterSelect(TreeViewEventArgs e)
{
// Confirm that the user initiated the selection.
// This prevents the first node from expanding when it is
// automatically selected during the initialization of
// the TreeView control.
if (e.Action != TreeViewAction.Unknown)
{
if (e.Node.IsExpanded)
{
e.Node.Collapse();
}
else
{
e.Node.Expand();
}
}
// Remove the selection. This allows the same node to be
// clicked twice in succession to toggle the expansion state.
SelectedNode = null;
}
