WPF Converter Converterparameter binding multi-parameter

1. Converterparameter is not a dependency property, so the binding cannot be used.

2. The converter interface IValueConverter can be changed to Imultivalueconverter to achieve multipleMultiBinding

3. Imultivalueconverter code, for example:

     Public classMultibooltocolorconverter:imultivalueconverter { Public ObjectConvert (Object[] values, Type targetType,Objectparameter, System.Globalization.CultureInfo culture) {            varcolor = SYSTEM.WINDOWS.MEDIA.COLOR.FROMRGB (0x31,0x89,0xC6);//"#3189c6";            if(values.) All (v = (v is BOOL&& (BOOL) (v)) | | Values. All (v = (v is BOOL&& (BOOL) v==false)) {color= SYSTEM.WINDOWS.MEDIA.COLOR.FROMRGB (0x89,0xBB,0xE0);//"#89BBE0";            }            return NewSystem.Windows.Media.SolidColorBrush (color); }         Public Object[] Convertback (ObjectValue, type[] targettypes,Objectparameter, System.Globalization.CultureInfo culture) {            Throw NewNotSupportedException (); }    }

4.xmal file notation, for example:

  <UserControl.Resources>        <cv:multibooltocolorconverter x:key="mutiboolconverter "/>    </UserControl.Resources>

<style targettype="FrameworkElement"> <setter property="Visibility"> <Setter.Value> <multibinding converter="{StaticResource Accessleveltovisibilityconverter}"> <binding path="Tag"Relativesource="{RelativeSource Mode=findancestor,Ancestortype=usercontrol}"/><binding path="Tag"Relativesource="{RelativeSource Mode=self}"/> </MultiBinding> </Setter.Value> </Setter></Style>

OR

<button content="Test">                <Button.Background>                    <multibinding converter="{StaticResource mutiboolconverter}">                        <binding path=" isenablecredentialsadded "/>                        <binding path="isold"/>                    </multibinding >                </Button.Background>             </Button>
