Can I explicity show tooltip on Mouse Click event in WPF?

Question

I am showing a Tool Tip when Mouse hovers on Help image.

The xaml is given below:

 <Image 
     x:Name="HelpImage"
     Width="16"
     Height="16"
     Grid.Row="1"
     Source="..\Images\ToolBar\Help.png"
     Grid.Column="2">
     <Image.ToolTip>
         <Grid
             Background="LightGreen">
             <Grid.RowDefinitions>
                 <RowDefinition />
                 <RowDefinition />
             </Grid.RowDefinitions>
             <StackPanel
                 Background="LightGreen"
                 Height="25"
                 Width="300"
                 Orientation="Horizontal"
                 HorizontalAlignment="Left"
                 VerticalAlignment="Top">
                 <Image
                     VerticalAlignment="Stretch"
                     HorizontalAlignment="Stretch"
                     Width="24"
                     Height="24"
                     Source="/Images/Test.png"
                     Name="image1" />
                 <TextBlock
                     FontFamily="Aharoni"
                     Margin="5"
                     FontSize="20"
                     FontWeight="Bold"
                     Foreground="Black"
                     TextWrapping="Wrap"
                     VerticalAlignment="Top"
                     Height="Auto"
                     HorizontalAlignment="Right"
                     Width="Auto">
                       <Run
                          FontFamily="Calibri"
                          FontSize="14"
                          Foreground="DarkRed"
                          FontWeight="Bold"
                          Text="Bandwidth Base Value" />
                 </TextBlock>
             </StackPanel>
             <TextBlock
                 Grid.Row="1"
                 Background="LightGreen">
                 This is Help  content</TextBlock>
         </Grid>
     </Image.ToolTip>
 </Image>

It shows the Tool Tip when user mouse hovers on the image control. Can I explicity show ToolTip when user clicks on the image ?

Please Help!!

You can force the tool tip to open by setting ToolTip.IsOpen to true. You can get a reference to the ToolTip object by explicitly constructing one when setting the ToolTip property. Instead of

<Image.ToolTip>
    <Grid>
    ...
    </Grid>
</Image.ToolTip>

write

<Image.ToolTip>
    <ToolTip>
        <Grid>
        ...
        </Grid>
    </ToolTip>
</Image.ToolTip>

And then in your MouseUp handler do something like:

((ToolTip)((FrameworkElement)sender).ToolTip).IsOpen = true;

Many Thanks for the solution.. It worked for me. But where should I set the IsOpen property to false ? I want to close the tool tip if user click anywhere outside the tool tip.

Ashish Ashu Over a year ago

I have handled UserControl_MouseLeftButtonUp in which I have written ((ToolTip)((FrameworkElement)this.HelpImage).ToolTip).IsOpen = false; But this event executes as soon as I do mouse up on Image control.

@AshishAshu I set IsOpen to false in ToolTip.Closed event.

set ToolTip.IsOpen to false on the Image.MouseLeave event

No you can't invoked the tooltip on mouseclick. Instead of using Tooltip, you can use Popup control. Invoke the Popup Control on mouse click.

EventManager.RegisterClassHandler(typeof(Window), Mouse.MouseDownEvent, 
                                  new MouseButtonEventHandler((o, args) => 
                                  { 
                                      if (_popup.IsOpen) 
                                          _popup.IsOpen = false; 
                                  }));
