WPF--Blend制作Button控件模板

博客园新人,WPF初学者。不涉及理论知识,直接进入操作。

记录一下使用Blend制作Button控件模板过程中,学到Blend几个知识点:

1、渐变画笔编辑器的Alpha选项可以调控件的透明度。即下图的A,可以调节百分比

渐变过程可以加上渐变点,以达到颜色的层次分明。如下图:

2、控件模板的应用,通过ControlTemplates建立。以Button模板为例:

建立一个矩形框或者Button,然后在上图位置选择“编辑当前模板”选项,即为下图:

此时可以编辑相应的模板,按钮的形状颜色等等;
在项目栏旁边选择状态栏(states),可以编辑鼠标按下时的颜色状态,甚至可以调节出动画效果。如下图

并且可以应用该模板。如下图

以上过程基本是一个控件模板的制作过程,具体细节按照设计要求来调。jv9在《Expression Blend实例中文教程》第13章有详细介绍。发一下模板代码:
    <Style x:Key="BtnS1" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid>

                                <VisualState x:Name="MouseOver">
