wpf Radio Button DataBindings

Hi,

I have two radiobuttons on my view and there IsChecked property is binded to the ViewModel property IsDynamic , problem

is that when i change the selection of first radion button first time the binding works ,but when i check another

radion button the IsChecked property is not updated. I am using the enum boolean converter. My xaml file

is

<

 

 

RadioButton Grid.Column="0" Content="Static" IsChecked="{Binding Path=IsDynamic, Converter={StaticResource enumBooleanConverter },ConverterParameter=Static,Mode=TwoWay}" TabIndex="1" GroupName="Static"/>

 

 

 

 

 

 

<RadioButton Content="Dynamic" Grid.Row="1" Margin="0,30,96,16" IsChecked="{Binding Path=IsDynamic, Converter={StaticResource enumBooleanConverter},ConverterParameter=Dynamic,Mode=TwoWay}" IsEnabled="{Binding IsDynamicViewEnabled}" TabIndex="2" Width="61" IsHitTestVisible="False" Checked="RadioButton_Checked" GroupName

="Dynamic"/>

and the EnumBooleanConverter is

 

 

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

 

 

string parameterString = parameter as string;

 

 

if (parameterString == null)

 

 

return DependencyProperty.UnsetValue;

 

 

if (Enum.IsDefined(value.GetType(), value) == false)

 

 

return DependencyProperty.UnsetValue;

 

 

object parameterValue = Enum.Parse(value.GetType(), parameterString);

 

 

return parameterValue.Equals(value);

 

}

 

 

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

 

 

 

string parameterString = parameter as string;

 

 

if (parameterString == null)

 

 

return DependencyProperty.UnsetValue;

 

 

return Enum.Parse(targetType, parameterString);

 

}

The isDynamic property on ViewModel is as follows

 

 

 

 

 

 

 

 

 

 

public

 

 

 

AccountSetDynamic

IsDynamic

{

 

 

 

set

{

 

 

 

//this.currentAccountSet.IsDynamic = value;

 

 

 

if (value.Equals(AccountSetDynamic

.Dynamic))

{

 

 

 

 

this.CurrentAccountSet.IsDynamic = true

;

}

 

 

 

else if(value.Equals(AccountSetDynamic

.Static))

{

 

 

 

 

this.CurrentAccountSet.IsDynamic = false

;

}

 

 

 

this.isDynamic = value

;

 

 

 

this.RaisePropertyChanged(() => this

.IsDynamic);

}

 

 

 

get

{

 

 

 

return this

.isDynamic;

}

and the ENUM is as follows

 

 

public enum AccountSetDynamic

{

Static=0,

Dynamic=1

}

i cannot figure out where i am doing wrong ,please help out
