I am wondering how I can bind a DataGrid DataGridTemplateColumn to a property in that isn't in the DataGrid ItemSource, but the property is within the same DataContext of the Itemsource?
XAML
// I am trying to bind the Visibility property to a property called Visible
<DataGridTemplateColumn Header="Apply" Visibility="{Binding source Visible}">
// However the visible property doesnt exist inside the resource cvsCustomers
ItemsSource="{Binding Source={StaticResource CustomerCollection}}"
C#
// But they both live in the same ViewModel i.e. DataContext
private Visibility m_Visible = Visibility.Hidden;
public Visibility Visible
{
get { return m_Visible; }
set { m_Visible = value; }
}
private ObservableCollection<Customer> m_CustomerCollection = null;
public ObservableCollection<Customer> CustomerCollection
{
get { return m_CustomerCollection; }
set { m_CustomerCollection = value; }
}
Can this be achieved?
Thanks
Datagrid columns does not comes under the visual tree of the DataGrid
. hence you will need to use the BindingProxy to make ViewModel accessible to your DataGridTemplateColumn
. I have explained how to create and use BindingProxy
in the answer below:
Bind ViewModel property to DataGridComboBoxColum
Once you have setup the BindingProxy you can bind your DataGridTemplateColumn visiblity as
<DataGridTemplateColumn Header="Apply" Visibility="{Binding Path=Data.Visible, Source={StaticResource ProxyElement}"
