给 TextBox文本框前添加图片
扩展PhoneTextBox:添加一个类“ExtentPhoneTextBox”继承 PhoneTextBox ，在“ExtentPhoneTextBox”类中添加属性项：
复制代码 代码如下:
public class ExtentPhoneTextBox : PhoneTextBox
{
/// summary>
/// 文本框图片属性
/// /summary>
public static readonly DependencyProperty TextHeadImageProperty =
DependencyProperty.Register("TextHeadImage", typeof(ImageSource), typeof(ExtentPhoneTextBox), new PropertyMetadata(null)
);
/// summary>
/// 文本框头图片
/// /summary>
public ImageSource TextHeadImage
{
get { return base.GetValue(TextHeadImageProperty) as ImageSource; }
set { base.SetValue(TextHeadImageProperty, value); }
}
/// summary>
/// 文本图片宽度
/// /summary>
public double TextHeadImageWidth
{
get { return (double)GetValue(TextHeadImageWidthProperty); }
set { SetValue(TextHeadImageWidthProperty, value); }
}
// Using a DependencyProperty as the backing store for TextHeadImageWidth. This enables animation, styling, binding, etc...
public static readonly DependencyProperty TextHeadImageWidthProperty =
DependencyProperty.Register("TextHeadImageWidth", typeof(double), typeof(ExtentPhoneTextBox), new PropertyMetadata(null));
/// summary>
/// 文本图片高度
/// /summary>
public double TextHeadImageHeight
{
get { return (double)GetValue(TextHeadImageHeightProperty); }
set { SetValue(TextHeadImageHeightProperty, value); }
}
// Using a DependencyProperty as the backing store for TextHeadImageHeight. This enables animation, styling, binding, etc...
public static readonly DependencyProperty TextHeadImageHeightProperty =
DependencyProperty.Register("TextHeadImageHeight", typeof(double), typeof(ExtentPhoneTextBox), new PropertyMetadata(null));
}
}
ExtentPhoneText 样式编辑：
全部样式如下：
