在我的Windows phone7应用程序中,我只需为按钮的每个状态(Normal,mouseOver,Pressed,disabled)创建一个具有不同图像的自定义按钮。
如果我只是想为每个具有不同背景颜色的状态创建一个自定义按钮,那么我会按照以下步骤完成它。
1. Open the page with Expresion Blend
2. Right click button -> Edit Template -> Edit a copy
3. Select Background (In the "Objects and Timeline" Section)
4. Select each "state" under the "state" tab and start adding backgroung color with the "Pressed" state from the properties pannel.
* Ultimately Can add this as follows for all the buttons which require this custom style
Style="{StaticResource ButtonStyle1}"
我尝试按照上述步骤以类似的方式为每个州分配背景图像。
但问题是,当我自动添加一个状态所需的图像时,它也适用于所有其他状态。所以最终它最终为所有状态添加相同的图像(最后为任何状态添加图像)。
如果有人能解释为windows phone7的表达式混合中的每个状态创建一个自定义按钮以及不同图像的步骤,我将非常感激。提前致谢....!!!

添加图像时,基本上设置按钮模板的外观,这与按钮状态无关。要实现您想要的效果,您可以创建一个包含两个图像的按钮模板,然后使用状态显示或隐藏相应的图像。
1. Edit Button Template
2. Add images to the Grid level of the template
3. Highlight each image item and Send to Back to make sure they are behind your border/content
4. Select a State (e.g. Normal, Pressed), highlight one of the images and set the Visibility property to Visible. Highlight the other image and set the Visibility property to Collapsed.
5. Select the other States and do something similar depending on what you what shown.
你的XAML看起来应该是这样的。为简洁起见,删除了一些内容。
