问题描述
我如何更改按钮模板动态？
我有一个组合框其中，通过改变自己的选择的价值我想换一个按钮 模板。
这是我一直在努力做的事情：
＆LT; Window.Resources＆GT;
＆LT;控件模板X：键=ButtonControlTemplate1的TargetType ={X：类型按钮}＆GT;
＆LT;网格和GT;
＆LT;矩形填充=＃FF2D2D7A保证金=7.5,9.5,8.5,11行程=黑
半径X =45半径=45StrokeThickness =6/＆GT;
＆LT; /网格和GT;
＆LT; /控件模板＆GT;
＆LT;控件模板X：键=ButtonControlTemplate2的TargetType ={X：类型按钮}＆GT;
＆LT;网格和GT;
＆LT; ED：正多边形填写=＃FFE7F9C9HEIGHT =自动InnerRadius =0.47211
保证金=20.5,16,15.5,8PointCount =5拉伸=填充
行程=黑StrokeThickness =6WIDTH =自动/＆GT;
＆LT; /网格和GT;
＆LT; /控件模板＆GT;
＆LT; /Window.Resources>＆LT;电网X：NAME =LayoutRoot＆GT;
＆LT;组合框名称=GroupBoxHeaderComboBox的ItemsSource ={绑定路径=集合}
的DisplayMemberPath =密钥HEIGHT =52保证金=211.5,60,230.5,0
VerticalAlignment =顶级的SelectedIndex =1/＆GT;
＆LT;按钮内容=按钮的HorizontalAlignment =左HEIGHT =102保证金=47.5,0,0,91
VerticalAlignment =底WIDTH =132
模板={DynamicResource ButtonControlTemplate2}/＆GT;
＆LT;按钮内容=按钮的HorizontalAlignment =右HEIGHT =112.5保证金=0,0,27.5,85
VerticalAlignment =底WIDTH =153
模板={DynamicResource ButtonControlTemplate1}/＆GT;
＆LT;按钮内容=按钮HEIGHT =102保证金=239.5,0,252.5,13.5
VerticalAlignment =底
模板={绑定的ElementName = GroupBoxHeaderComboBox，路径= SelectedItem.Value}/＆GT;
＆LT; /网格和GT;
和这里有关联的模板取值：
＆LT; Window.Resources＆GT;
＆LT;控件模板X：键=ButtonControlTemplate1的TargetType ={X：类型按钮}＆GT;
＆LT;网格和GT;
＆LT;矩形填充=＃FF2D2D7A保证金=7.5,9.5,8.5,11行程=黑
半径X =45半径=45StrokeThickness =6/＆GT;
＆LT; /网格和GT;
＆LT; /控件模板＆GT;
＆LT;控件模板X：键=ButtonControlTemplate2的TargetType ={X：类型按钮}＆GT;
＆LT;网格和GT;
＆LT; ED：正多边形填写=＃FFE7F9C9HEIGHT =自动InnerRadius =0.47211
保证金=20.5,16,15.5,8PointCount =5拉伸=填充
行程=黑StrokeThickness =6WIDTH =自动/＆GT;
＆LT; /网格和GT;
＆LT; /控件模板＆GT;
＆LT; /Window.Resources>
和背后的code：
公共部分类主窗口：窗口
{
公共字典＆LT;字符串，字符串＆GT;采集
{
得到;
私人集;
} 公共主窗口（）
{
this.InitializeComponent（）;
的DataContext =这一点;
收集=新词典＆LT;字符串，字符串＆GT;（）
{
{DynamicResource ButtonControlTemplate2，{DynamicResource ButtonControlTemplate2}}，
{DynamicResource ButtonControlTemplate1，{DynamicResource ButtonControlTemplate2}}， };
需要下面这点创建对象//将code。
}
}
有没有acomplish这另一种方式genric？......我想，大部分的code将是XAML。
编辑：
有一个点使用样式办呢？比方说，我想要更多然后一个对象采取行动，否则就是有一点改变风格，并从那里做这一切？
解决方案
公共部分类主窗口：窗口
{
公共主窗口（）
{
的InitializeComponent（）; 的DataContext =这一点;
} 公共字典＆LT;字符串的ControlTemplate＆GT;采集
{
得到
{
字典＆LT;字符串的ControlTemplate＆GT; CONTROLTEMPLATES =新词典＆LT;字符串的ControlTemplate＆GT;（）;
controlTemplates.Add（ButtonControlTemplate1，FindResource（ButtonControlTemplate1）作为的ControlTemplate）;
controlTemplates.Add（ButtonControlTemplate2，FindResource（ButtonControlTemplate2）作为的ControlTemplate）;
返回CONTROLTEMPLATES;
}
}
}
How can I change a Button template dynamically?
I have a ComboBox where by changing his selected value I want to change a Button Template. This is what I have been trying to do:
<Window.Resources>
<ControlTemplate x:Key="ButtonControlTemplate1" TargetType="{x:Type Button}">
<Grid>
<Rectangle Fill="#FF2D2D7A" Margin="7.5,9.5,8.5,11" Stroke="Black"
RadiusX="45" RadiusY="45" StrokeThickness="6"/>
</Grid>
</ControlTemplate>
<ControlTemplate x:Key="ButtonControlTemplate2" TargetType="{x:Type Button}">
<Grid>
<ed:RegularPolygon Fill="#FFE7F9C9" Height="Auto" InnerRadius="0.47211"
Margin="20.5,16,15.5,8" PointCount="5" Stretch="Fill"
Stroke="Black" StrokeThickness="6" Width="Auto"/>
</Grid>
</ControlTemplate>
</Window.Resources>
<Grid x:Name="LayoutRoot">
<ComboBox Name="GroupBoxHeaderComboBox" ItemsSource="{Binding Path=collection}"
DisplayMemberPath="Key" Height="52" Margin="211.5,60,230.5,0"
VerticalAlignment="Top" SelectedIndex="1"/>
<Button Content="Button" HorizontalAlignment="Left" Height="102" Margin="47.5,0,0,91"
VerticalAlignment="Bottom" Width="132"
Template="{DynamicResource ButtonControlTemplate2}"/>
<Button Content="Button" HorizontalAlignment="Right" Height="112.5" Margin="0,0,27.5,85"
VerticalAlignment="Bottom" Width="153"
Template="{DynamicResource ButtonControlTemplate1}"/>
<Button Content="Button" Height="102" Margin="239.5,0,252.5,13.5"
VerticalAlignment="Bottom"
Template="{Binding ElementName=GroupBoxHeaderComboBox, Path=SelectedItem.Value}"/>
</Grid>
And here are the associated Templates:
<Window.Resources>
<ControlTemplate x:Key="ButtonControlTemplate1" TargetType="{x:Type Button}">
<Grid>
<Rectangle Fill="#FF2D2D7A" Margin="7.5,9.5,8.5,11" Stroke="Black"
RadiusX="45" RadiusY="45" StrokeThickness="6"/>
</Grid>
</ControlTemplate>
<ControlTemplate x:Key="ButtonControlTemplate2" TargetType="{x:Type Button}">
<Grid>
<ed:RegularPolygon Fill="#FFE7F9C9" Height="Auto" InnerRadius="0.47211"
Margin="20.5,16,15.5,8" PointCount="5" Stretch="Fill"
Stroke="Black" StrokeThickness="6" Width="Auto"/>
</Grid>
</ControlTemplate>
</Window.Resources>
And the code behind:
public partial class MainWindow : Window
{
public Dictionary<string, string> collection
{
get;
private set;
}
public MainWindow()
{
this.InitializeComponent();
DataContext = this;
collection = new Dictionary<string, string>()
{
{ "DynamicResource ButtonControlTemplate2", "{DynamicResource ButtonControlTemplate2}"},
{ "DynamicResource ButtonControlTemplate1", "{DynamicResource ButtonControlTemplate2}"},
};
// Insert code required on object creation below this point.
}
}
Is there another genric way to acomplish this?... I want that most of the code would be xaml.
EDIT:
Is there a point to do it using a style? Let's say I want more then one object to act, otherwise is there a point to change the style and to do it all from there?
解决方案
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = this;
}
public Dictionary<string, ControlTemplate> collection
{
get
{
Dictionary<string, ControlTemplate> controlTemplates = new Dictionary<string, ControlTemplate>();
controlTemplates.Add("ButtonControlTemplate1", FindResource("ButtonControlTemplate1") as ControlTemplate);
controlTemplates.Add("ButtonControlTemplate2", FindResource("ButtonControlTemplate2") as ControlTemplate);
return controlTemplates;
}
}
}
