WPF 复选框问题

Question

I have a checkbox in my xaml which is bind to a property and even if the property is false, it is not making the checkbox disabled.

Here is the xaml:

<DataGridTemplateColumn Header="checkBox" Width="60">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox  IsChecked="{Binding Path=IsClickable}"/> 
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

viewModel.cs

    public bool IsClickable
    {
        get { return _isClickable; }
        set { _isClickable = value;
            PropertChanged("IsClickable");}
    }

And I m setting this property at the time of object creation.

And im binding the datagrid using itemsource;

 Datagrid.ItemsSource = ViewModels;

And I can see that the object collection of viewmodel does have that property populated as false.But is not disabling the checkbox.

Can some one tell me why please?

You're binding the IsChecked property, but if you want to enable/disable the CheckBox , you need to bind the IsEnabled property:

<CheckBox IsEnabled="{Binding Path=IsClickable}" />

(you will probably need to bind IsChecked to something else, otherwise you won't be able to retrieve the checked state)
