WPF自定义控件的应用（DynamicResource的使用方法）

news 2025/6/27 23:40:31

1 DynamicResource的使用方法
可以在字典文件的抬头区写入数：

 <SolidColorBrush x:Key="PrimaryBackgroundColor" Color="#FFABAdB3"/><SolidColorBrush x:Key="TextBox.MouseOver.Border" Color="#FF7EB4EA"/><SolidColorBrush x:Key="TextSecundaryColor" Color="#FF569DE5"/>

设定好颜色：
则引用时直接使用：

 BorderBrush="{DynamicResource PrimaryBackgroundColor}"

另一种方式引用 fontFamily 的方式与此相似

  <FontFamily x:Key="HgFont">../../CommonInMy/Fonts/#iconfont</FontFamily>

当然这个只是写在
节点下，如果想整个项目都用这个链接方法就是直接写在 app.xaml 下；
在这里插入图片描述
引用方式 FontFamily="{ DynamicResource HgFont}"
2 自定义控件（数据增减下拉操作）
2.1 控件本身类

public class UInputNumberTextBox : Control{ static UInputNumberTextBox(){DefaultStyleKeyProperty.OverrideMetadata(typeof(UInputNumberTextBox), new FrameworkPropertyMetadata(typeof(UInputNumberTextBox)));}private Button btnSubtract;private Button btnAdd;public int Text{get { return (int)GetValue(TextProperty); }set { SetValue(TextProperty, value); }}// Using a DependencyProperty as the backing store for Text.  This enables animation, styling, binding, etc...public static readonly DependencyProperty TextProperty =DependencyProperty.Register("Text", typeof(int), typeof(UInputNumberTextBox), new PropertyMetadata(0));public override void OnApplyTemplate(){base.OnApplyTemplate();btnSubtract = GetTemplateChild("btnSubtract") as Button;if (btnSubtract != null){btnSubtract.Click += BtnSubtract_Click;}btnAdd = GetTemplateChild("btnAdd") as Button;if (btnAdd != null){btnAdd.Click += BtnAdd_Click;}}private void BtnAdd_Click(object sender, RoutedEventArgs e){UInputNumberTextBox inputText = this as UInputNumberTextBox;inputText.Text += 1;}private void BtnSubtract_Click(object sender, RoutedEventArgs e){UInputNumberTextBox inputText = this as UInputNumberTextBox;inputText.Text -= 1;}}

2.2 样式操作：

<SolidColorBrush x:Key="PrimaryBackgroundColor" Color="#FFCFD6E5"/><!--定义颜色--><SolidColorBrush x:Key="TextBox.MouseOver.Border" Color="#FF7EB4EA"/><SolidColorBrush x:Key="TextSecundaryColor" Color="#FF4E85BD"/><!--<FontFamily x:Key="TextSecundaryColor" fa="#FF569DE5"/>--><Style x:Key="ControNumberTB" TargetType="ControlSet:UInputNumberTextBox"><Setter Property="Background" Value="{DynamicResource PrimaryBackgroundColor}" /><Setter Property="SnapsToDevicePixels" Value="True" /><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="ControlSet:UInputNumberTextBox"><BorderWidth="{TemplateBinding Width}"Height="{TemplateBinding Height}"BorderBrush="{DynamicResource PrimaryBackgroundColor}"BorderThickness="1"><StackPanel Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Orientation="Horizontal" ><Grid Width="{TemplateBinding Width}"><Grid.ColumnDefinitions><ColumnDefinition Width="*" /><ColumnDefinition Width="2*" /><ColumnDefinition Width="*" /></Grid.ColumnDefinitions><Buttonx:Name="btnSubtract"Grid.Column="0"Width="{TemplateBinding Height}"Height="{TemplateBinding Height}"HorizontalAlignment="Left"VerticalAlignment="Center"Background="{DynamicResource PrimaryBackgroundColor}"BorderThickness="0,0,0,0"Content="&#xf068;"Cursor="Hand"FocusVisualStyle="{x:Null}"FontFamily="{DynamicResource  HgFont}"Foreground="{DynamicResource TextSecundaryColor}" /><!--减号--><TextBoxGrid.Column="1"HorizontalAlignment="Center"VerticalAlignment="Center"Background="Transparent"BorderThickness="0"FocusVisualStyle="{x:Null}"FontSize="{TemplateBinding FontSize}"Foreground="{TemplateBinding Foreground}"Text="{Binding Text, RelativeSource={RelativeSource AncestorType=ControlSet:UInputNumberTextBox}, Mode=TwoWay}" /><Buttonx:Name="btnAdd"Grid.Column="2"Width="{TemplateBinding Height}"Height="{TemplateBinding Height}"HorizontalAlignment="Right"VerticalAlignment="Center"Background="{DynamicResource PrimaryBackgroundColor}"BorderThickness="0,0,0,0"Content="&#xf067;"Cursor="Hand"FocusVisualStyle="{x:Null}"FontFamily="{ DynamicResource  HgFont}"Foreground="{DynamicResource TextSecundaryColor}" /> <!--加号--></Grid></StackPanel></Border></ControlTemplate></Setter.Value></Setter></Style>

3.引用在界面XAML中。
引用地址：
xmlns：自定义 = ”clr-namespace:地址

 xmlns:ControlSet="clr-namespace:海王牌位系统.CommonInMy.Controls"

引用

  <ResourceDictionary Source="../../CommonInMy/Styles/UInputNumberTextBoxStyle.xaml"/>

界面定义，本关键字加名称

 <ControlSet:UInputNumberTextBox  Grid.Row="6" Grid.Column="1" Width="200"  Height="30"  Margin="0,0,0,10"  FontSize="16"  Style="{DynamicResource ControNumberTB }"  Text="1" />
