validating controls in tabs winforms

Im implementing application which has main window and in this second window which has a lot of tabs in tabcontrol.

On each tab I have a lot of control which values may be edited by user, some of them has to be filled, some need to has values between x and y and so on.

Main windows has got sa开发者_开发知识库ve button. Point is that if in any tab control isnt validated then saving shouldnt be possible and appropriate tab should be opened and validation shown. Could you please tell me any advice of how to create such mechanism ? Maybe any generic methods ?

thanks for help

WinForms TabControl validation: Switch to a tab where validation failed

            var tabControlList = new HashSet<Control>();
            _tabControls[tab] = tabControlList;
            foreach (Control control in tab.Controls)
            {
                var capturedControl = control; //this is necessary
                control.Validating += (sender, e) =>
                    tabControlList.Add(capturedControl);
                control.Validated += (sender, e) =>
                    tabControlList.Remove(capturedControl);
            }
        }
    }

        else
        {
            var unvalidatedTabs = _tabControls.Where(kvp => kvp.Value.Count != 0)
                                              .Select(kvp => kvp.Key);
            TabPage firstUnvalidated = unvalidatedTabs.FirstOrDefault();
            if (firstUnvalidated != null && 
                !unvalidatedTabs.Contains(OptionTabs.SelectedTab))
                    OptionTabs.SelectedTab = firstUnvalidated;
        }
    }
