WPF: Bind Control Enabled to Checkbox Checked

July 23rd, 2009

This is a simple example of a nifty use of binding in WPF.

Say you have an element in your application such as a TextBox, ComboBox, or some RadioButtons that you want to keep disabled to the user unless the user checks a box. You may even want to disable a whole section of controls contained inside of a StackPanel or DockPanel.

Everything enabled

To accomplish this you bind the IsEnabled property of the target control (in this case a ComboBox) to the IsChecked property of the CheckBox.


    <CheckBox x:Name="chkEnableBackup">Run Backup Sets</CheckBox>
    <StackPanel Orientation="Horizontal">
        <Label Margin="12,0,0,0">Run backup every</Label>
        <ComboBox Width="70" SelectedIndex="0"
          IsEnabled="{Binding ElementName=chkEnableBackup, Path=IsChecked}">

That’s it! Our result is that when the box is not checked the control is disabled.

Control disabled!
