Provide access to Custom Control Method

Hi Talha,

I don't get what you want to do. It would be helpful to have some code that shows what you're doing and where the problem is. :)

I have a control like this. To expose the properties of inner control, I used binding. So, the user of CustomListView can change properties of inner ListView by changing CustomListView properties. Now, I have written a EventHandler for "Checkbox.Checked" and "Checkbox.Unchecked" in code behind of CustomListView.(Say EventHandler is named CheckChangedHandler)

CustomListView can be used like this:

<Page xmlns="http://ift.tt/w9rHWX;

        <Style TargetType="Controls:CustomListView" x:Key="CListViewStyle1">
            <Setter Property="Height" Value="346" />
            <Setter Property="Width" Value="425" />
            <Setter Property="VerticalAlignment" Value="Top" />

                              Margin="10"
                              VerticalAlignment="Top"
                              IsChecked="{Binding IsChecked, Mode=TwoWay}"
                              Width="27" />

                    <TextBlock Grid.Column="1"
                               TextAlignment="Center"
                               Text="{Binding Content.Column1, RelativeSource={RelativeSource Mode=TemplatedParent}}"
                               Margin="22,10,0,0"
                               TextWrapping="Wrap"
                               FontStyle="Normal"
                               FontWeight="Bold"

                               Height="24"
                               x:Name="Header1"
                               Foreground="#FFB2BF8F" />
                </StackPanel>
            </Border>
        </DataTemplate>
    </Page.Resources>

        <Controls:CustomListView x:Name="allSubjectsList"
                                 Margin="266,141,0,0"
                                 Header="{Binding AllSubjectsHeader}"
                                 ItemsSource="{Binding AvailibleSubjects}"
                                 Style="{StaticResource CListViewStyle1}"
                                 HeaderTemplate="{StaticResource AllSubjectsHeaderTemplate}"
                                 />
</Page>

As you can see, user can change templates of CustomListView->RootListView. Now, there is a checkbox in Datatemplate user applied as HeaderTemplate. I want to give user ability to add following line in that checkbox.

<CheckBox Checked=<!-- Event Handler for check changed defined in CustomListView code behind -->
/>

Hope, you understands this.
