Can I bind event to a button?

Anonymous User 1847 23-Sep-2013

I have collection of such classes:

public class class1

{                 

    public double first {get;set;}

    public double second {get;set;}

    public void divide(object sender, RoutedEventArgs e)

    {

        first/=2;

        second/=2;

    }

}

ObservableCollection<class1> collection1;

That are displayed using wpf and databinding:

<Listbox ItemsSource="{Binding collection1}" >

<ListBox.ItemTemplate>

    <DataTemplate>

        <WrapPanel>

            <TextBox Text="{Binding first}" />

            <TextBox Text="{Binding second}" />

            <Button Content="Divide" />

        </WrapPanel>

    </DataTemplate>

</ListBox.ItemTemplate>

My question is: can I somehow bind each button to it's instance's function divide?

wpf

Hi Lois,

Assuming you're using a code-behind (.xaml.cs), you can define an event handler like this there:

private void DivideButton_Click(object sender,
RoutedEventArgs e) {
    var button =(Button)e.Source;  // <-- the specific
button that was clicked
    var c1 =(class1)button.DataContext;  // <--
the instance bound to this button
    c1.Divide();
}

In class1:

public void Divide() {
    first/=2;
    second/=2;
}

In XAML:

<DataTemplate>
    <WrapPanel>
        <TextBox Text="{Binding first}" />
        <TextBox Text="{Binding second}" />
        <Button Content="Divide" Click="DivideButton_Click" />
    </WrapPanel>
</DataTemplate>
