Dear Support!

In Zenon 15 you add function to set dynamically filter in CEL screen like below:

My question is:

Exist any way to get "string text filter" set by keybord "DialogKbd" where i put filter text(for example if i change value for any variable  you have system variable which set current modified variable and next i can get it but i can not find any way to do something similar for controls), or maybe directly from Cel control after set this filter..?

I need it because if filter is set i have to put them to Report export pdf function similar way like time as below:

I found dynamic property whare i can set filter () but i can not get this string.

Thanks for advance!
