I have a data grid with checkboxes in a column. When the user checks a checkbox i need to get the data of that line and put it into a var to use later (i need to add the price of all the selected attachments and put it into a field). When the user unchecks a checkbox i need to remove the data of that line from the var. This is the code that i have so far in the data grid's script:

Code: Select all

on mouseUp pMouseBtnNum
   if pMouseBtnNum is 1 then
      if the short name of the target is "Check" then
         if the hilite of button "Check" is true then
            answer "checked"
         else
            answer "unchecked"
         end if
      end if
   end if
end mouseUp

(the 2 answers are to see what happens)
This code works correctly only for the first row in the data grid. If i check/uncheck another row it always answers "checked".
Also the dgDataOfLine, dgDataOfIndex, GetDataOfIndex and GetDataOfLine are empty so i don't have a way to get a lines data.

Could anyone please help me to do this?

Thanks,
Max

Hi Max,

is the datagrid a FORM or a TABLE?
If FORM, does it have a custom behavior?
If yes, did you already script what you want into the behavior?
If not, you should

What did you try with "dgDataOfLine, dgDataOfIndex, GetDataOfIndex, GetDataOfLine"?
That's the way to go, but maybe in another script?

It looks like you put your "mouseup" handler directly into the group script, right?
In that case this does happen:
1. you click the button of line 1 -> hilite of btn "Check" -> TRUE
2. Since Datagrids are a LOT of objects grouped together, you will have MORE than one button named "Check" on your card,
so asking "the hilite of btn Check" will only return the hilite of the FIRST button (lowest layer) named "Check"!
Uncheck that first button and you will always get "unchecked"!

As always, datagrids ARE complex beasts

Hi Keram,

better open a new thread for your problem, no idea if and when the OP will ever answer.
