I have designed some WPF CustomControl and I wrote a ControlTemplate for them, and i assigned ControlTemplates to those controls through styles :
for Example:
public class BootstrapText : TextBox
{
protected override void OnLostFocus(RoutedEventArgs e)
{
// ...
}
protected override void OnTextChanged(TextChangedEventArgs e)
{
// ...
base.OnTextChanged(e);
}
public static readonly DependencyProperty RegexProperty = DependencyProperty.Register("Regex", typeof(string), typeof(BootstrapText), new PropertyMetadata(null));
public bool IsValid
{
// ...
}
public string Regex
{
// ...
}
static BootstrapText()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(BootstrapText), new FrameworkPropertyMetadata(typeof(BootstrapText)));
}
}
and ControlTemplate (Actually Style) is Something like:
<Style TargetType="Controls:BootstrapText" BasedOn="{StaticResource FontBase}">
<Setter Property="Padding" Value="2"/>
<Setter Property="Width" Value="240"/>
<Setter Property="SnapsToDevicePixels" Value="True"></Setter>
<Setter Property="Background" Value="#FEFEFE"/>
<!--<Setter Property="VerticalContentAlignment" Value="Center"/>-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Controls:BootstrapText">
<Grid>
<Border Name="container" HorizontalAlignment="Left" Padding="{TemplateBinding Padding}" Height="{TemplateBinding Height}" BorderThickness="1" BorderBrush="#ccc" Background="{TemplateBinding Background}">
<ScrollViewer Padding="0" x:Name="PART_ContentHost" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}" TextBlock.TextAlignment="Center" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
While i have no x:Key="SomeKey"
in the style. this style will affects all BootstrapText
s.
This is Good. But I have another problem. Somewhere in a Form, I want to Style these Controls and Set some Margin and Padding for them but leave the defaults as they are. but my Control will be disappeared !!!
I think twice styling will hides the default style.
In the standard Controls like TextBox
, Button
, ... whenever we write some style, everything is good and style simply sets our properties.
I think, I must assign my ControlTemplate directly to the CustomControl Because i must get ride of this Styling process. but I don't know how ?
