Solution 1

There is no tooltip set in the code shared. If you are seeing one, then it is set somewhere else - code that is not shared in the question. Check against the actual code in the Page or View or in the code-behind.

Update
Why not simply work with the ToolTipService and the IsEnabled property. Example:

C#

<TextBox Text="Is Enable Test" Width="100"
         ToolTipService.IsEnabled ="{Binding ElementName=EnabledState, Path=IsChecked}"
         ToolTipService.ToolTip="This is a tooltip for the textbox"/>
<CheckBox x:Name="EnabledState" Content="Show Tooltip" IsChecked="True" Margin="10 0" />

            <Label Content="Information"/>
            <TextBox Template="{DynamicResource TextboxWithWatermark}" ToolTip="First name" Margin="1"/>
            <TextBox Template="{DynamicResource TextboxWithWatermark}" ToolTip="Last name" Margin="1"/>
            <TextBox Template="{DynamicResource TextboxWithWatermark}" ToolTip="Address" Margin="1"/>
            <TextBox Template="{DynamicResource TextboxWithWatermark}" ToolTip="E-mail address" Margin="1"/>

        </StackPanel>

I'm not understanding why you would do that - sounds very odd.

But if you want to hide/show on Mouse, you have two choices:
1. Styles: use event triggers for MouseEnter & MouseLeave
2. ControlTemplate (as above) you use the VisualStateManager

Had another thought for you. Check out the updated solution.

ToolTipService.IsEnabled is working, Thank you

Now the ToolTip become a textbox's watermark when textbox is string.empty without showing any tooltip on mouse over

<Trigger Property="IsMouseOver" Value="true"> <Setter Property="ToolTipService.IsEnabled" Value="False"/>
I'm not sure this's right how to use. But it still work
