WPF- How to set wpf datagrid row validation errors to a separate textblock?

In WPF i have a DataDrid with different validations. so far i used ToolTip in the DataGrid to show the error validation.

Now the client asked to show the validation error in on different TextBlock/Label in the page- how do i do that? How do i use the: (Validation.Errors)[0].ErrorContent outside the DataGrid?

thats what i had till now:

<DataGrid.RowValidationErrorTemplate> <ControlTemplate> <Grid Margin="0,-2,0,-2" ToolTip="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type DataGridRow}},Path=(Validation.Errors)[0].ErrorContent}"> <Ellipse StrokeThickness="0" Fill="Red" Width="{TemplateBinding FontSize}" Height="{TemplateBinding FontSize}" /> <TextBlock Text="!" FontSize="{TemplateBinding FontSize}" FontWeight="Bold" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Grid> </ControlTemplate> </DataGrid.RowValidationErrorTemplate>
