Accessing datagrid on card 2 from card 1 - acting weird

[BarrySumpter]

I could have sworn this was working yesterday without problems.

On Card 1 I have 1 Button.
Button 1 - places data in a DataGrid on Card 2
- then goes to Card 2.

Now as sson as I attempt to load data into the DataGrid on Card 2 the code exits my routine without errors (Ithink).

Is there something I sould know about pre-loading Card 2 before trying to access the DataGrid on Card 2?

I've experimented and can Go To Card 2
then continue the script on Card 1 that loads the data into the datagrid on Card 2 but I get a flicker.

A bit more experimentation shows that surounding my code with lock screen and unlock screen fixes the flicker.

Can't seem to workout why it was working without issue yesterday but not today.
