I have datagrid control in my project and i want to add tooltip to datagridcells. I customized the tooltip control and put a textbox control in it. I tried to bind cell content value to textbox but it did not work.

When I use the Tooltip contol directly (without customizing) it is worked.

This is xaml code:

Without customizing the tooltip binding is working.

    <Style TargetType="{x:Type DataGridCell}">
        <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self},Path=Content.Text}"/>          
    </Style>

But customized tooltip binding is not working.

<Style TargetType="DataGridCell">
    <Setter Property="ToolTip">
        <Setter.Value>
            <TextBox Text="{Binding RelativeSource={RelativeSource Self},Path=Content.Text}"/>
        </Setter.Value>
    </Setter>
    
   
</Style>
