Click Button from Generic.xaml?

Question

I am writing a custom control in Silverlight and I am having issues getting my Button to click to the Generic.xaml file. This does not work:

Answer 1

You have to override the OnApplyTemplate() on your custom control class (C# File).

Like this.

    public override void OnApplyTemplate()
    {
        Button btn = GetTemplateChild("ScrollLeft") as Button;
        Debug.Assert(btn != null);
    }

Also, you have to make one more change in the control template in Generic.Xaml like below.

<Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:CustomControl1}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                    <Button Grid.Row="0" Grid.Column="0" x:Name="ScrollLeft">&lt;</Button>
                </Border>
            </ControlTemplate>
        </Setter.Value>

Note: I removed the Click event handler.

Although is it possible I recommend using Commands so the designer who replaces the template is free to pick other controls and events to bind the logic to.
