Regarding TreeGridpanel as showed in demo37
Is it possible to edit the values of a column by a left click?
Can you give me some examples please?
In current version of TreeGridPanel is not possible to edit any cell.
However, you could add a "detail" panel, for instance below the treegrid and use it to edit data (i.e. using a Form panel having the same v.o. used in a row of treegrid...)
