It is possible. 

There are several ways to do this. 

1. Use workflows. See https://help-2021r2.acumatica.com/(W(2))/Help?ScreenId=ShowWiki&pageid=cbbac950-4172-42c7-b950-a589a87df249
2. Use something like 
               �ActionName].SetEnabled(true); in RowSelected event
3. Set access rights in the code
   ePXUIField(DisplayName = “COPIER MARGE”, MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]

hi @SadokHanini  

In continuation to @Dmitrii Naumov  suggestion, to brief more below is the example  for button to get enabled in sales order, you can try similar way on your screen 

syntax 

  protected virtual void DACName_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected baseEvent)

{

   condition and logic 

}

note: here Base Event parameter is required  only when we customized the existing screen for new screen customization this parameter is not required 

Example 

  protected virtual void SOOrder_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected baseEvent)
        {

            if (baseEvent != null)
                baseEvent(cache, e);
            SOOrder row = (SOOrder)e.Row;
            if (row == null) return;

             KNCPAlternateItems.SetEnabled(row.Status == "Completed");

}
