wpf圖片顯示文字

1. WPF 一行上3個控制項 左右都是圖片 中間是文字 如果文字過長 會覆蓋右邊的圖片 該如何解決

你是要實現這2個iamge控制項同時顯示同一個圖片嗎，如果是的話就用數據綁定

2. WPF中什麼控制項能夠既顯示圖片，又顯示文字

其實不改模板就可以實現的呢。因為Button本身是一個ContentControl，所以裡面可以塞任何控制項的。demo如下： 文本內容

3. 用WPF編程，本來在canvas上顯示圖像了。如何在上面繼續顯示文字啊謝謝了

4. （跪求）WPF下的RichTextBox控制項下動態添加文字和圖片

。。。靈活一點！！！在StackPanl內放image跟RichtextBox兩個控制項，分別存放圖片跟文字不是一樣能解決問題嗎？

5. c# WPF panel 裡面有個listview，listview裡面有圖片和文字，怎麼能將這個listview在列印預覽中顯示出來

6. WPF中哪種組件可以實現以下文字顯示效果

WPF中沒有直接的控制項能夠達到這個效果，要自己寫控制項。給你寫了個自定義控制項的例子，代碼如下：

【代碼1】自定義控制項RowTextPresenter，提供隔行效果的控制項。（示例代碼，僅僅封裝了FontSize和FontFamily屬性，你可以仿造示例自行封裝）

privatevoidDrawRows()

varlineHeight=lineMetrics.ReflectGetProperty<double>("Height");

//判斷奇偶行，繪制背景塊

if(i%2==baseValue)

{

dc.DrawRectangle(this.AlternationBackground,null,newRect(0,offsetY,width,lineHeight));

}

offsetY+=lineHeight;

}

}

dc.Close();

}

【代碼2】ReflectionService，提供反射功能的工具類

usingSystem;

usingSystem.Collections.Generic;

usingSystem.Linq;

usingSystem.Text;

usingSystem.Reflection;

namespaceWpfTextRow.Controls

{

{

=

BindingFlags.Public|

BindingFlags.NonPublic|

BindingFlags.Instance;

<T>(thisobjecttarget,stringpropertyName)

{

vartype=target.GetType();

varpropertyInfo=type.GetProperty(propertyName,ReflectionFlags);

return(T)propertyInfo.GetValue(target,null);

}

publicstaticobjectReflectCall(thisobjecttarget,stringmethodName,paramsobject[]args)

{

vartype=target.GetType();

varpropertyInfo=type.GetMethod(methodName,ReflectionFlags);

returnpropertyInfo.Invoke(target,args);

}

}

}
