我终于解决了我的自我...





Xaml

 <  按钮     高度  =  23   名称  =  btnGoLineitem   宽度  =  40     BorderBrush   = < span class =code-keyword>透明    Grid.Row   =  5    Grid.Column   =  4    Horizo​​ntalAlignment   =  Left    点击  =  btnGoLineitem_Click   >  
 <   Button.Template  >  
 <   ControlTemplate  >  
 <  图片   < span class =code-attribute> Source   =  .. \Images\NewItem.png   名称  =  imgLineItemAdd   >  <   / Image  >  
 <   / ControlTemplate  >  
 <   / Button.Template  >  

首先获取您在设计模式中定义的控制模板（xaml）

 ControlTemplate ct = btnGoLineitem.Template; 
 
访问xaml端存在的图像标记
 
图像btnImage =（图像）ct.FindName（imgLineItemAdd，btnGoLineitem）; 

现在只需更改图像源

 btnImage.Source = new BitmapImage（new Uri（ ../../Change.png，UriKind.RelativeOrAbsolute））;

Hi,
I solved it my self yar finally....


Xaml

<Button  Height="23" Name="btnGoLineitem" Width="40" BorderBrush="Transparent" Grid.Row="5" Grid.Column="4" HorizontalAlignment="Left" Click="btnGoLineitem_Click" >
   <Button.Template>
       <ControlTemplate>
         <Image Source="..\Images\NewItem.png" Name="imgLineItemAdd" ></Image>
        </ControlTemplate>
   </Button.Template>

First Get access of control template which you have defined in design mode(xaml)

ControlTemplate ct = btnGoLineitem.Template;

Get access of the image tag that is present in the xaml side

 Image btnImage = (Image)ct.FindName("imgLineItemAdd", btnGoLineitem);

Now just change the image source

btnImage.Source = new BitmapImage(new Uri("../../Change.png", UriKind.RelativeOrAbsolute));
