TreeView Cancel Expand/Collapse

[Mc Brain]

Is there anyway to avoid a node to be collapsed or expanded when doubled-click. I know I can expand and/or collapse the node in the DoubleClick event... but I don't wan't the user to see the expand and collapse -or collapse and expand regarding it's initial status). TIA,

I guess maybe you count mouseclicks in the MouseDown events and trap the BeforeExpand/Collapse events (Ithink that's what they're called) to cancel the expand/collapse and reset the mouseclick counter. Also you would need some sort of timer to reset the mouseclick counter as well. Seems a bit of a crude hack though, must be a better way of doing it.

Also maybe something on this page might help you.

I only found these events on .Net. Does VB6 also have them?

Yes I just looked them up, they are called Expand and Collapse

Ok, I might not explain myself correctly. I want to cancel the expand/collapse if the user double-clicks only. That example avoids to expand/collapse even with the "+" and "-".

Yes, but those events fires after the action itself. So, when I get to this point... the node has already been expanded or collapsed. I know I can collapse it or expand it but this is the flickering I want to avoid.
