thanks but it doesn't work! because my binding value is different and just its configuration is the same. this is my code:
<UserControl.Resources>
<Style TargetType="TextBox">
<Setter Property="MinWidth" Value="160" />
</Style>
</UserControl.Resources>
...
<TextBox x:Name="Name" Text="{Binding Model.Name , UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=true , ValidatesOnExceptions = true }" />
<TextBox x:Name="Title" Text="{Binding Model.Title , UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=true , ValidatesOnExceptions = true }" />
