Datagrid Bug

[alasdair23]

I've found what I can only describe as a "bug" with Datagrids on Mac OS X. I am a reasonably competent RunRev coder, so I hope that this is just a case of me not reading a particular bit of documentation... however:

In the enclosed stack there are two data grids - one shows 7 lines [of 30] and the other shows 23 lines [of 30]. Populate the grids with the same content.
Then when one clicks on an item in the grid, it puts it's long name in the messagebox.

However, if one scrolls [in ether grid] down to reveal the lower items and clicks on these, the WRONG name is returned.

Looks like this has something to do with scrolling. I can't imaging this is a feature.

HELP!

Hi Alasdair,

this is the way it works!
Check "cached controls" for the grids and all is fine!

When this is UNCHECKED, then the DG library will only copy that much template groups to the datagrid that are VISIBLE in the grid!
If checked then ALL necessary groups are copied to the datagrid at once.

In any way do NOT rely on the names of the groups and their containing objects if possible

And since this is not OS X specific, I will move this thread to the "Talking LiveCode" forum.

Fascinating. But where is this "cached controls" to be found?

Hi Craig,

in the inspector "Basic Properties" right under the "lineheight" text field.
Oh, it is named "cache controls" without a D

Ah. I didn't see it because it is grayed out. What property allows it to be checked?

Thanks,

Craig

Hi Craig,

this is only available for "Form" datagrids.
