In my project, which search data from my database, I have some parameters for searching.
For each parameter I have a pair: combobox with a list of parameters for the selection and textbox to display the selected parameter.
All this works fine.
But when I put such a pair (combobox + textbox) in a groupbox, I get a searching without this parameter.
If I put the combobox + textbox out of the groupbox again , then everything works fine.
I can solve this without groupboxes but I am interested in why this happens?
