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:

Answer 1

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

Answer 2

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;

Answer 3

OnClick set visibility of tooltip true and in ToolTipClosing set visibility c

....

Answer 4

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.
