How do you disable tooltips in code at runtime

Question

Hi

Can anyone tell me how you disable tooltips in code at runtime. I want to add an option to hide tooltips dynamically.

Answer 2

Hi

Thanks for the reply. That is certainly an option, however I'm wondering if there is a way to do it in code iteratively before I go and change all of my xaml.

If you want to disable the tool tip for the elements residing in the Window, you could try using inheritable attached property trick as illustrated at the following sample code:

Code Snippet

<Window x:Class="AnswerHarness.ToggleToolTipsDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:cc="clr-namespace:AnswerHarness"
    Title="ToggleToolTipsDemo" Height="300" Width="300" Name="window">
  <StackPanel>
    <CheckBox IsChecked="{Binding Path=(cc:ToolTipBehavior.IsToolTipEnabled), ElementName=window}" Content="Enable ToolTip"/>
    <Border BorderBrush="Green" BorderThickness="1" Background="Yellow" ToolTip="Border">
      <StackPanel>
        <Button Width="120" Height="30" Content="Button1" ToolTip="Button1"/>
        <Button Width="120" Height="30" Content="Button2" ToolTip="Button2"/>
        <Button Width="120" Height="30" Content="Button3" ToolTip="Button3"/>
      </StackPanel>
    </Border>
  </StackPanel>
</Window>

public class ToolTipBehavior
{
    public static Boolean GetIsToolTipEnabled(FrameworkElement obj)
    {
        return (Boolean)obj.GetValue(ToolTipEnabledProperty);
    }

    public static void SetToolTipEnabled(FrameworkElement obj, Boolean value)
    {
        obj.SetValue(ToolTipEnabledProperty, value);
    }

    public static readonly DependencyProperty ToolTipEnabledProperty = DependencyProperty.RegisterAttached(
        "IsToolTipEnabled",
        typeof(Boolean),
        typeof(ToolTipBehavior),
        new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.Inherits, (sender, e) => 
        {
            FrameworkElement element = sender as FrameworkElement;
            if (element != null)
            {
                element.SetValue(ToolTipService.IsEnabledProperty, e.NewValue);
            }
        }));
}

public partial class ToggleToolTipsDemo : Window
{
    public ToggleToolTipsDemo()
    {
        InitializeComponent();

        // You can programmatically disable tool tip here.
        this.SetValue(ToolTipBehavior.ToolTipEnabledProperty, false);
    }
}

Hope this helps

Wow, that looks pretty nifty. I'll have to give that a go. At the moment I've done it iteratively but it's not ideal because of having to handle different types.

Code Snippet

public static void SetToolTipEnabled(Object obj, bool enabled)
        {
           

            if (obj is FrameworkElement)
            {
                FrameworkElement fe = (FrameworkElement)obj;

                if (obj is System.Windows.Controls.Control)
                {
                    System.Windows.Controls.ToolTipService.SetIsEnabled(obj as System.Windows.Controls.Control, enabled);
                }
                else if (obj is System.Windows.Controls.Image)
                {
                    System.Windows.Controls.ToolTipService.SetIsEnabled(obj as System.Windows.Controls.Image, enabled);
                }

                // recurse through the children
                IEnumerable children = LogicalTreeHelper.GetChildren(fe);
                foreach (object child in children)
                {
                    SetToolTipEnabled(child, enabled);
                }

            }


        }
