clickability in a DataGrid

[dunbarx at aol.com]

Hi.


There are a few ways to do this. The old fashioned way is to write in the group script:


on mouseUp
  put the target
end mouseUp


You get a result that is easily deconstructed to row and column references.


You can also trap the "editFieldText" message, or any of the row and column properties.

Hi Sieg,
I can't think of a way to detect a click in a specific cell of a datagrid.

If nobody else can come up with something, a couple of alternatives would
be to customize your Edit and Delete columns to contain buttons and put
your delete/edit commands in the mouseUp handler for each button, or
implement a right click popup menu with delete/edit options on it and put
the logic in the menuPick handler for the popup.

Would take too much space to describe how to do those things, but check out
the datagrid manual for details.
