Checking if Control is held

Hi All,

When dealing with a tree view control, is it possible to check if the user is holding down the control key when they click on a node?

Ive noticed that the treeview does not allow the highlighting on multiple node so im going to implement it myself, however ctrl+click is the standard way of selecting multiple items in windows and I would like it to remain as such in my application (for ease of learning how to use it etc)

If it is not possible to check for CTRL, is it possible to check for a keystroke?

for example, the user clicks on a node and then presses a key, node becomes highlighted.

It might be worth mentioning ill implement highlighting by adjusting the back colour not trying to actually select multiple nodes (im looking for a quick fix).

Thanks in advance for you help

Rich.

Just handle the KeyDown event and check e.Control parameter value to see whether the control key is pressed or not
