checkbox wpf 绑定数组,WPF数据绑定CheckBox.IsChecked

How would I bind the IsChecked member of a CheckBox to a member variable in my form?

(I realize I can access it directly, but I am trying to learn about databinding and WPF)

Below is my failed attempt to get this working.

XAML:

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="Title" Height="386" Width="563" WindowStyle="SingleBorderWindow">

TabIndex="2" Margin="0,12,30,0"

Checked="checkBoxShowPending_CheckedChanged"

Height="17" Width="92"

VerticalAlignment="Top" HorizontalAlignment="Right"

Content="Show Pending" IsChecked="{Binding ShowPending}">

Code:

namespace MyProject

{

public partial class Form1 : Window

{

private ListViewColumnSorter lvwColumnSorter;

public bool? ShowPending

{

get { return this.showPending; }

set { this.showPending = value; }

}

private bool showPending = false;

private void checkBoxShowPending_CheckedChanged(object sender, EventArgs e)

{

//checking showPending.Value here. It's always false

}

}

}

解决方案

Note i added a name to , and changed the binding in your CheckBox. You will need to implement ShowPending as a DependencyProperty as well if you want it to be able to update when changed.
