WPF's use of the Visibility property for item template switching

The foreground XAML is as follows:

<Grid. Resources>     <xx:accountstatustovisibility  x:key= "accountstatustovisibility" / > </grid.resources> <Telerik:radbutton Visibility= "{Binding Status, Mode=oneway, Converter={staticresource accountstatustovisibility}, converterparameter=disabled} " 
Margin= "0 0 5 0"Click= "Radbutton_click"
Command= "{Binding path=datacontext.cmddisabled, Relativesource={relativesource ancestortype={x:type Telerik: RadGridView} }} " >Set Enable</Telerik:radbutton>

Background, template switch class:

 Public classAccountstatustovisibility:ivalueconverter {#region"IValueConverter Members" Public ObjectConvert (ObjectValue, Type TargetType,Objectparameter, System.Globalization.CultureInfo culture) {                 if(Value = =NULL)                 {                     return false; }                 if(Parameter! =NULL)                 {                     Switch(parameter. ToString ()) { Case "Enabled":                             return((int) Value = =0) ?Visibility.Collapsed:Visibility.Visible;  Case "Disabled":                             return((int) Value = =1) ?Visibility.Collapsed:Visibility.Visible; //Case "Invaild"://return ((int) value = = 2)? Visibility.Collapsed:Visibility.Visible;                     }                 }                 return false; }              Public ObjectConvertback (ObjectValue, Type TargetType,Objectparameter, System.Globalization.CultureInfo culture) {                 Throw Newnotimplementedexception (); }             #endregion     }
