Possibily to hide/unhide a node

[olivier_dehorter]

Add the possibility to hide/unhide a node AND their child too should be great (at least for me)

In what component?

HI

Oups

This is AdvColumnGrid, but it seems it is the same for ADvTreeView

If you expand the node, you should be able to use grid.HideRow() on main node row + child rows in TAdvColumnGrid

Hi Bruno

that's what I thought too. however, the result is totally unexpected

I joined a small project to demonstrate that.

Thanks for feedback

Almost ;)

When I clicked in this order on button 1 then 2 => the node id2 is empty but visible. I would prefer it to be invisible
So, not possible to see only node '1' and '3' ?

Not the Note that in the other direction (2 then 1), the result is totally different.

Perform the hiding after the grouping.

Hi

It works, but I have to change the code to hide/suppress the rows.

I joined the code to others users :

    FOR i := 1 TO 15 DO
    BEGIN
        IF AdvColumnGrid1.IsNode(i) AND (AdvColumnGrid1.Cells[1, i] = '2') THEN
        BEGIN   // Node to hide/suppress
            AdvColumnGrid1.SuppressRows(i, i + AdvColumnGrid1.GetNodeSpan(i) - 1)
        END;
    END;

Thanks you
