Datagrid dgHilitedLines of group is blank

[cusingerBUSCw5N]

I have been in Datagrid hell all day. I have a series of datagrids that are bringing in information from a url(turl) call. The information is loading properly. I want the user to be able to select an item in the datagrid (a button) and then do something with it. The problem is that many of the buttons inside the datagrid don't recognize script asking for the dghilitedlines of the group - and return a blank, rather than the data.

I thought something might be corrupt, so I deleted my preferences file, switched to Indy 7.1.7, tried it on new cards, and even started a new stack. The datagrid on the new stack fails as well. Some of the datagrids with the same code work on my original stack. However, I am attaching the stack with only one datagrid on it that is failing for me (ie. when you click on the button inside the datagrid, it returns empty, instead of giving me the data for that line.)

The script loading the info takes tresult and does this:

Code: Select all

split tresult by RETURN
      repeat with x=1 to tnum
            set the itemdelimiter to TAB
          split tresult[x] by TAB 
          put tresult[x][1] into theDataB[x]["bizname_facebook2"]

          //put tresult[x][2] into theDataB[x]["facebook2"]
 end repeat


set the dgData of group "datagrid_facebook" to theDataB

The datagrid's script is:

[code]put pDataArray["bizname_facebook2"] into tuse
   answer tuse & " in datagrid"
   set the label of button "bizname_facebook" of me to tuse

Here is the script for the buttons:

Code: Select all

       put the dgHilitedLines of group "datagrid_facebook" into theLine  --grabs hilited line

     put the dgDataOfLine[theLine] of group "datagrid_facebook" into theDataA
     -- theDataA is now an array variable.
     -- then you get the specific column values by using the column names
     put theDataA["bizname_facebook2"] into tuse
     answer tuse

It is supposed to give me the name on the button

I have been messing around with this for 10 hours.... and am at a complete loss. Any help out there? I am on Windows 10 with Indy 7.1.7 Thank you

I should also say that earlier, i tried turning my computer off and then on again...and the datagrid worked (meaning that the button returned the information that was requested). But then it quickly went back into failure mode.

The dgHilitedLines was empty, so theDataA also empty.

Turning on row autohilite for the datagrid, it works.

(But datagrids are not always the easiest solution for some tasks.)

Your code needs repeat, ans the group name is not welcomed to livecode (I don't know why), so this code works:

########CODE to copy and paste#######
on MouseUp
put the dgHilitedLines of group "temp1" into theLine --grabs hilited line
answer theLine
repeat for each item tItem in theLine
put the dgDataOfLine[tItem] of group "temp1" into theDataA
-- theDataA is now an array variable.
-- then you get the specific column values by using the column names
put theDataA["col 1"] & return after tuse
end repeat
answer tuse
end MouseUP
