代码注意事项：
1、代码实现的样式赋值
XXX.Style = TryFindResource("StyleName") as Style;
2.WPF中FindName方法的使用
(1)简单的使用 前台代码：
<Button x:Name="btnName" Click="btnName_Click">Test Method FindName</Button> |
后台代码:
private void btnName_Click(object sender, RoutedEventArgs e)
{
Button b = FindName("btnName") as Button;
MessageBox.Show(b.Name);
}
（2）在模板中使用FindName方法
<Grid> <Grid x:Name="childGrid"> <Button x:Name="rootBtn"> <Button.Template> <ControlTemplate> <Button x:Name="btnName" Click="btnName_Click">Test Method FindName</Button> </ControlTemplate> </Button.Template> </Button> </Grid> </Grid> |
后台代码：
private void btnName_Click(object sender, RoutedEventArgs e) { Button b = rootBtn.Template.FindName("btnName",rootBtn) as Button; MessageBox.Show(b.Name); } |
3.使用多个绑定参数
<Button Height="23" Command="{Binding AddCommand}" Content="计算" HorizontalAlignment="Left" Margin="20,0,0,49" Name="button1" VerticalAlignment="Bottom" Width="75"> <Button.CommandParameter> <MultiBinding Converter="{StaticResource ParameterConverter}"> <Binding Path="Text" ElementName="textBox1"/> <Binding Path="Text" ElementName="textBox2"/> </MultiBinding> </Button.CommandParameter> |
4、将代码写在XAML中
<Grid> <x:Code> <![CDATA[ private void button1_Click(object sender, RoutedEventArgs e) { button1.Background = Brushes.Blue; button1.Content = "The code is in XAML"; MessageBox.Show("hi"); } ]]></x:Code> <Button Height="23" Margin="46,56,32,0" Name="button1" VerticalAlignment="Top" Click="button1_Click">Click me!</Button></Grid> |
5、各属性对应的C#代码
5.1<Window><Grid><Button ...></Grid></window>
等效代码如下：
Grid g = new Grid();Button b = new Button();b.Width = 100;b.Height = 100;b.Content = "Test Button";b.Foreground = Brushes.LightBlue;g.Children.Add(b);myWindow.AddChild(g); |
6、ItemContainerGenerator.ContainerFromIndex方法的使用
TreeViewItem item = (TreeViewItem)myTreeView.ItemContainerGenerator.ContainerFromIndex(1); |
7、WPF获取子控件和父控件方法
public class Globals { /// <summary> /// 获取父控件方法。该方法将根据当前控件，遍历查找其父控件是否存在。参数1是表示当前子控件名，参数2是要查询父控件名； /// </summary> public T GetParentObject<T>(DependencyObject obj, string name) where T : FrameworkElement { DependencyObject parent = VisualTreeHelper.GetParent(obj); while (parent != null) { if (parent is T && (((T)parent).Name == name | string.IsNullOrEmpty(name))) { return (T)parent; } parent = VisualTreeHelper.GetParent(parent); } return null; } /// <summary> /// 该方法将根据当前控件，遍历查找其子控件是否存在。参数1是表示当前父控件名，参数2是要查询子控件名； /// </summary> public T GetChildObject<T>(DependencyObject obj, string name) where T : FrameworkElement { DependencyObject child = null; T grandChild = null; for (int i = 0; i <= VisualTreeHelper.GetChildrenCount(obj) - 1; i++) { child = VisualTreeHelper.GetChild(obj, i); if (child is T && (((T)child).Name == name | string.IsNullOrEmpty(name))) { return (T)child; } else { grandChild = GetChildObject<T>(child, name); if (grandChild != null) return grandChild; } } return null; } /// <summary> /// 该方法将把所有子控件作为List集合返回到客户端。 /// 其中第一个参数是父控件参数，而第二个参数是特定子控件名称， /// 如果需要遍历全部子控件，第二个参数留空即可。 /// </summary> public List<T> GetChildObjects<T>(DependencyObject obj, string name) where T : FrameworkElement { DependencyObject child = null; List<T> childList = new List<T>(); for (int i = 0; i <= VisualTreeHelper.GetChildrenCount(obj) - 1; i++) { child = VisualTreeHelper.GetChild(obj, i); if (child is T && (((T)child).Name == name || string.IsNullOrEmpty(name))) { childList.Add((T)child); } childList.AddRange(GetChildObjects<T>(child, "")); } return childList; } } |
XAML：
Globals VTHelper = new Globals();StackPanel sp = VTHelper.GetChildObject<StackPanel>(this.LayoutRoot, "spDemoPanel");Grid layoutGrid = VTHelper.GetParentObject<Grid>(this.spDemoPanel, "LayoutRoot");List<TextBlock> textblock = VTHelper.GetChildObjects<TextBlock>(this.LayoutRoot, ""); |
8.GridSplitter控件的使用：
<Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="90*" /> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="180*" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="190*" /> <RowDefinition Height="Auto" /> <RowDefinition Height="70*" /> </Grid.RowDefinitions> <Button Content="ButtonA" Margin="3" Grid.Row="0" Grid.Column="0" Grid.RowSpan="3" /> <Button Content="ButtonB" Margin="3" Grid.Row="0" Grid.Column="2" /> <Button Content="ButtonC" Margin="3" Grid.Row="2" Grid.Column="2" /> <GridSplitter Width="3" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Row="0" Grid.Column="1" Grid.RowSpan="3"></GridSplitter> <GridSplitter Height="3" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.Row="1" Grid.Column="2"></GridSplitter></Grid> |
效果图:
9.UniformGrid控件中每行没列都相等
<UniformGrid> <Button Content="ButtonA" /> <Button Content="ButtonB" /> <Button Content="ButtonC" /> <Button Content="ButtonD" /> <Button Content="ButtonE" /> <Button Content="ButtonF" /> <Button Content="ButtonG" /> <Button Content="ButtonH" /> </UniformGrid> |
