Hi, I have a hierarchical grid (two levels:parent rows and child rows).
The first cell on the left is the checkbox and if I want I can use checkbox for open the relative parent row (with his child rows).When I use the first checkbox (for open all parent rows and relative child rows) the time for do this is aceptable (for 300 rows about 5 seconds).Also the time to close all is good. The problem is when I have open all (for example I have my 300 rows) and I want close only one parent row (with his child rows):infact sometimes for close only one parent rows I must wait 50/60 seconds and same thing for open the specific parent row when the other are all open. I suppose the problem is that when I want to open or close only one parent row, the grid control do control on all rows and this is really slow..Is there something for open only one parent row and block the control on the entire grid?
Thanks in advance
Andrea
