Hello Everybody

I use a treeview to show structured data from our electronic archiv.
When doubleclicking on a node i call an "archivviewer.exe" to show the wanted archiv data (pdf,tif...)

But when doubleclicking on a node, the node is also expanded or shrinked.

I want to stop this behavior and put a "nodefault" in my doubleclick event.
No success.
The node is still expanded or shrinked and then the archiv viewer starts.

I don't know how to prevent the treeview nodes from being expanded when doubleclicking ??

Any help welcomed

Best regards

Albert
