Everyone knows how great tooltips are. In fact you wouldn’t even think of not creating a Windows app without them, most likely.

Now, with the wonderful StackPanel, you can have not only text, but images too.

Inside your button XAML, add a tooltip section (Button.ToolTip), add your actual Tooltip section inside that. Then, inside your Tooltip section, add a Stackpanel. Inside that StackPanel, merely add a text block AND an image file. You’d end up with something similar to this:

                        <TextBlock Margin="3"
                            FontSize="14">Text Goes Here</TextBlock>
                        <Image Source="images/yourImage.jpg" />

Create any mixture of the above you’d like. It’s possible to create some really nice looking tooltips this way
