Hi,
I have a grid where all cells are locked except the last column which is a checkbox. Anyway, the customer asked to be able to do a multi select of cells. My goal is to simply read all selected cells to toggle the value of the checkbox.
So I started to play with the multiselect for grids and tried to read multiple lines without success. I mean, I can read the first cells and then the second one by using "grid read next", but how to iterate to the next one? It loops on the same cell? Do I need to do something special to just loop on each selected cells by the user? I've also tried a "grid goto" to force a proper read after the "grid read next", but this "unselects" previous cells.
I'm doing my test with version 18 (local version, not windx) if that matters...
Thanks
When you say SELECTED do you mean the rows of the grid whose check box is checked?
If so the best solution would be to read the whole grid into a single string using GRID FIND ctlno,0,0,string$. You can then parse the string row by row (delimited by $0a$), and extract the last column (delimited by SEP). This will allow you to find which rows to process.
To reset all the check boxes us a GRID WRITE ctlno, lastcolno, 0, ""
... where lastcolno is the column with the check box.
Hey Mike, no, sorry for the confusion! I'm really talking about the CELL selection by using the CTRL-MOUSECLICK or SHIFT-MOUSECLICK.
So let'say there's a grid with 30 lines. The user click once on a cell in line 10 and then presses SHIFT and click line 20 from the same column. I want to read selected cells, so in this case from line 10 to 20.
