Treeview

[Jerry]

Hi,

I created a treeview. I filled it with all the nodes I need. Now I would
like to deaktivate some nodes and activate them upon a given input.
"isvisible" is readonly. Isn't there any "enabled" property like the
textboxes have? If not, how can this be done?


Thanks,

Jerry

Define "deactivate". Does it mean that the node can't be selected, that it's
greyed, something else?

Yepp Claes, that's what I meant.

I want it to be greyed out and that it can't be selected. Eric has a nice
page where he does this with a workaround. I'll try it tonight. Is there
another way?

Thanks,

Jerry

The BeforeSelect event is the way to go, just as Eric writes in his article.
You can change the color with the TreeNode.ForeColor property (not sure if
Eric covered that in his article). Setting it to SystemColors.GrayText
should give you the correct gray text.
