Add button click event to Custom RadShape

[Abhinav]

Hello there,

I want to add button click event to a button present in the Resource Dictionary (Generic.xaml) of a custom radShape 

<Style TargetType="{x:Type local:SideView}">
        <Setter Property="BorderBrush" Value="Black"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="Height" Value="50"/>
        <Setter Property="Width" Value="100"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:SideView}">
                    <Grid Background="{TemplateBinding Background}">

                        
                        <Rectangle Stroke="{TemplateBinding BorderBrush}" StrokeThickness="{TemplateBinding BorderThickness}" 
                                   Height="{TemplateBinding Height}"
                                   Width="{TemplateBinding Width}"/>
                        
                         <Button  HorizontalAlignment="Right" Height="20" Width="20" Visibility="{Binding RelativeSource={RelativeSource TemplatedParent}
                                                                                            ,Path=ButtonVisiblity,Mode=TwoWay}" 
                                  Click="Button_Click" Margin="5" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>    How can i do that???

Hi Abhinav,

In order to add click event in the Generic.xaml of your custom control you can do the following:

• Set x:Name on your Button 
• Override the OnApplyTemplate() method of your control
• Inside the method, get the Button with the GetTemplateChild() method
• Add click event to the Button

Here is an example:

public override void OnApplyTemplate()
{
    Button btn = (Button)this.GetTemplateChild("myShapeBtn");
    btn.Click += btn_Click;
    base.OnApplyTemplate();
}

I hope this helps.

Regards,
Martin
