Show/Hide DataGrid Columns XAML

I am trying to build a DataGrid with controls that will allow a user to Show/Hide the columns. My DataGrid will have something like 40 columns, and not all may be necessary all of the time. I have been able to do this exact thing with a ListView that uses a GridView. Here is the code:

<DataGrid Name="MyDataGrid" Grid.Row="2" Grid.Column="0" ItemsSource="{Binding ReportOrderingCustomersForSalesRepCollection}" Style="{DynamicResource styleDataGrid}" HeadersVisibility="All" AutoGenerateColumns="False" RowHeaderWidth="0" RowHeight="25">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Customer #" Binding="{Binding CustomerNumber}" Width="90" Visibility="{Binding ElementName=Visibility_Txt,Path=Text,Mode=OneWay}"/>
        <DataGridTextColumn Header="Customer Name" Binding="{Binding CustomerName}" Width="125" />
        <DataGridTemplateColumn Header="Email" CellTemplate="{StaticResource Email}" Width="150" />
    </DataGrid.Columns>
</DataGrid>
<!-- text box -->
<TextBox Name="Visiblility_Txt">
    <TextBox.Style>
        <Style TargetType="TextBox">
            <Style.Triggers>
                <DataTrigger Binding="{Binding ElementName=ColumnVisibilityCheck,Path=IsChecked}" Value="False">
                    <Setter Property="Text" Value="Collapsed" />
                </DataTrigger>
                <DataTrigger Binding="{Binding ElementName=ColumnVisibilityCheck,Path=IsChecked}" Value="True">
                    <Setter Property="Text" Value="Visible" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </TextBox.Style>
</TextBox>
<!-- checkbox -->
<CheckBox Content="Show/Hide Customer Number" Name="ColumnVisibilityCheck" IsChecked="True" />

So I have a DataGrid setup. The Visibility Property on the first DataGridTextColumn is set as a binding to the text property of "Visibility_Txt". The text on that text box will be set to either Collapsed or Visible depending if the ColumnVisibilityCheck is checked or not.

Like i said, this works with a listview, Why won't this work with a DataGrid?

Solution

Was able to find some more information on this. This link has a good answer/explanation. datagridtextcolumn-visibility-binding

It turns out that the columns of a DataGrid do not appear in the visual tree of a DataGrid.

But the answer is to use x:reference in the visibility binding, and a BooleanToVisibilityConverter:

<DataGridTextColumn Header="Customer #" x:Name="CustNum_Col" Visibility="{Binding Source={x:Reference VisibilityCheck}, Path=IsChecked,Converter={StaticResource ObjectToVisibilityConverter}}" />

Visual Studio will show the squiggly line under the binding saying that "object not set to instance of an object" but it this still appears to work.
