Setting Treeview properties at runtime

[NeilV]

Hi,

I am trying to set the properties for a TreeView control that i create at runtime but I get the following error:

'Microsoft.Web.UI.WebControls.TreeView' does not contain a definition for 'showLines'

the code i am running is:
TreeView tree = new TreeView();
tree.showLines=false;

I can set the properties for the tree at design time by using tags and it works fine. How come it work at runtime??

help!

Neil
