CTR Posted September 8, 2009 Report Share Posted September 8, 2009 I am trying to program a tree view with 2 columns. The second column I would like to be able to edit some of the line but not all of them. Does anyone know how to disable only one element in a tree view and still be able to select this line. When I use the Disabled? Property node, If I select this line the tree value is empty. Is it possible to know that I have slected that line? Thanks for your help! Quote Link to comment

Hi, You can catch the mouse-down event on the Tree control, and discard this event if a disabled element (row + column) was clicked. /J Quote Link to comment

You can discard the actual editing before the characters are shown. To be fancy I would sound a 'beep.vi'. Ton Quote Link to comment
