Thread weird problem with TGrids unbound

I think I found a bug.

I have an unbound grid with a bunch of rows and columns.

If I type edit something in the grid, the change doesn't get reflected until the user selects another grid cell.  Not even if the user presses return!

So using the demo below, change one cell, then press 'test for changes' and the change will not be found unless you edit a second cell.  

ITo get by for now, is there something I can call to finalize the unbound grid so I can read its cells accurately?

Thanks

Works fine here. I changed a single cell, pressed return to complete editing,
pressed the button, and got the change message.

Tested in the IDE 2.06B11, FF, Chrome.
Is it true you've installed multible Versions?
-  Elevate Web Builder 2
-  Elevate Web Builder 2 BETA
I would check the search paths.

Okay, if you don't press return, it doesn't take.  Users don't always press return.  I've tried the internal IE and firefox and both fail.

I thought that too, but there are no other subdirectories with beta versions on the hard disk.

Note, editing does not require a return key otherwise.  Like if you query a TEdit, you get the real-time value.  But the grid's values do not change until a return registers it.

I can force the correct answer if I move the column (or probably row) that is active.
with the following code


  Grid1.FirstColumn;
  Grid1.LastColumn;

before querying the data values.  This is what I will have to do for now.

This method will do what you want:

It will ensure that the column control is hidden and that the current cell is updated.
