Styling a tooltip in a datagridcolumn

Question

1.00/5 (1 vote)

See more:

I'm adding a ToolTip to my DataGrid so that some extra information is displayed when the user hovers over a certain column. I need to be able to style the ToolTip.

What I have tried:

I add a ToolTip to a column like so (for some reason I can't get the code to display right on this website);

<DataGridTextColumn Header="Summary" Binding="{Binding Notes}" Width="*">
<datagridtextcolumn.cellstyle>

<Setter Property="ToolTip" Value="{Binding Notes}"/>

The issue with this solution is that the font is far too small and is difficult to read. Is there a way I can add a custom ToolTip to the column that will allow me to change its font size?

Try something like this:

XML

<DataGridTextColumn Header='Name'
                    Binding='{Binding Path=Name}'  >
    <DataGridTextColumn.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="ToolTip">
                <Setter.Value>
                    <TextBlock FontSize='20'
                               Text='{Binding Name}' />
                </Setter.Value>
            </Setter>

        </Style>
    </DataGridTextColumn.CellStyle>
</DataGridTextColumn>

You can also show additional window when selection is changed :

XML

<DataGrid.RowDetailsTemplate>
    <DataTemplate>
        <Border Margin="10"
                Padding="10"
                BorderBrush="SteelBlue"
                BorderThickness="3"
                CornerRadius="5">
            <TextBlock Text="{Binding Path=Name}"
                       TextWrapping="Wrap"
                       FontSize="10">
            </TextBlock>
        </Border>
    </DataTemplate>
</DataGrid.RowDetailsTemplate>
