Hello good day,
I ask for your help since I want to add a button with which I can directly display the PI calculation data dialog window and then the selected value is stored in a textbox
I believe this dialog is only available when configuring a symbol like a PBValue or PBTrend. Programmatic access to Datasets is however possible.
Please chose menu Help -> PI ProcessBook Programmer's Reference and search the Index for Datasets Class. The Examples link brings up a choice of samples.
Which is the selected value you like to store in a TextBox control, the name of the Dataset chosen by the user?
Retrieving data ...
