ImageBrush出现TypeConverter问题

'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.' Line number '49' and line position '38'

Assuming the image is:

• Included in your project
• It's in a folder named "Images"
• The build action for the image is set to "Resource" (should be the default)

You can reference it like this:

<ImageBrush ImageSource=
   "pack://application:,,,/YourProjectName;component/Images/wood1_1000X1000.jpg";

This fixed the issue, I put the image in the project folder whithout including it in the project itself.

Width与MaxWidth的区别

当你所要控制的对象，宽度或者高度值总是变化，而不是你想要指定的固定值，那么很有可能设置成了MaxHeight(MaxWidth)

Label等其他控件字体颜色修改不了

这个是很有可能是定义一个全局的TextBook，且没有指定该Style的Key值。导致Label等控件的字体大小颜色无法修改。

模板虽好但莫随意使用

实例：试想下如果你将如下代码定义到你到的Resource中会发生什么奇妙的现象了？

 <DataTemplate DataType="{x:Type system:String}">
            <StackPanel>
                <Image Source="{Binding }" MinHeight="500" MaxHeight="600" MaxWidth="800" />
            </StackPanel>
        </DataTemplate>

ToolTip会变成这样，Button会变成一条线。
