Question

i would like to make a textblock tooltip conditionally visible.

i have the tooltip defined as:

<TextBlock>
    <TextBlock.ToolTip>
        <Grid>...</Grid>
    </TextBlock.ToolTip>
</TextBlock>

where would visibility property go in that definition? it doesn’t seem to like any of my guesses.

there are some suggestions of just working with grid visibility. the problem with that approach is making the grid invisible will still show empty tooltip box.. which is why i am trying to control tooltip visibility.

Try this. It won’t leave an empty frame.

<TextBlock Text="test">
        <TextBlock.ToolTip>
            <ToolTip Visibility="Visible">
                Hello
            </ToolTip>
        </TextBlock.ToolTip>
    </TextBlock>

<TextBlock Text="test">
        <TextBlock.ToolTip>
            <ToolTip Visibility="Hidden">
                Hello
            </ToolTip>
        </TextBlock.ToolTip>
    </TextBlock>
