Hi happy new year
My problem is the following, in Form1 I have 3 buttons, the 2 at the top open the FrmFruit and the FrmVegetable in the panel, the button next to the text boxes opens the FrmFruit outside of the panel.
If I open the form from the enter button, I enter the data in it and when I enter I send the data from the FrmFruit to Form1  without problem, but if I try it from the FrmFruit open in the panel, no data is passed to me, see if you can help me.
what I need is to be able to send the data from the FrmFruit open in the panel, without it closing or opening another form.

  12.   
  13.         if (formInterface != null)
