I have two questions about the filter function of "TAdvStringGrid".
Question 1:
Is it possible to change the icon (① in the image) depending on the use of the filter function?
Please let me know if there is a way to tell visually if the filter function is in use.
Question 2:
I need a good idea to add the following functions to the button in image ②.
I put one item in the filter.
Show All
Show X
(Image #④)
I want the button in image ② to have the ability to switch between "ALL" and "X" when pressed.
I would like some good ideas on how to achieve that. I would appreciate sample code if possible.
