C#实现Menu和ContextMenu自定义风格及contextMenu自定义
为了实现自定义的Menu和ContextMenu效果，下面演示代码通过派生ProfessionalColorTable类，在自定义的类中重写ProfessionalColorTable类的相关联的属性，从而实现自定义菜单效果。
usingSystem.Drawing;
usingSystem.Windows.Forms;
publicclassCustomToolStripColorTable:ProfessionalColorTable
{
///<summary>
///主菜单项被点击后，展开的下拉菜单面板的边框
///</summary>
publicoverrideColorMenuBorder
{
get
{
returnColor.FromArgb(37,37,37);
}
}
///<summary>
///鼠标移动到菜单项（主菜单及下拉菜单）时，下拉菜单项的边框
///</summary>
publicoverrideColorMenuItemBorder
{
get
{
returnColor.Transparent;
}
}
#region顶级菜单被选中背景颜色
publicoverrideColorMenuItemSelectedGradientBegin
{
get
{
returnColor.FromArgb(37,37,37);
}
}
publicoverrideColorMenuItemSelectedGradientEnd
{
get
{
returnColor.FromArgb(37,37,37);
}
}
#endregion
#region顶级菜单被按下是，菜单项背景色
publicoverrideColorMenuItemPressedGradientBegin
{
get
{
returnColor.Black;
}
}
publicoverrideColorMenuItemPressedGradientMiddle
{
get
{
returnColor.FromArgb(37,37,37);
}
}
publicoverrideColorMenuItemPressedGradientEnd
{
get
{
returnColor.Black;
}
}
#endregion
///<summary>
///菜单项被选中时的颜色
///</summary>
publicoverrideColorMenuItemSelected
{
get
{
returnColor.FromArgb(37,37,37);
}
}
#region下拉菜单面板背景设置（不包括下拉菜单项）
//下拉菜单面板背景一共分为2个部分，左边为图像区域，右侧为文本区域，需要分别设置
//ToolStripDropDownBackground设置文本部分的背景色
publicoverrideColorToolStripDropDownBackground
{
get
{
returnColor.Black;
}
}
//以ImageMarginGradient开头的3个设置的是图像部分的背景色，begin->end是从左到右的顺序
publicoverrideColorImageMarginGradientBegin
{
get
{
returnColor.Black;
}
}
publicoverrideColorImageMarginGradientMiddle
{
get
{
returnColor.Black;
}
}
publicoverrideColorImageMarginGradientEnd
{
get
{
returnColor.Black;
}
}
#endregion
}
然后对需要实现自定义风格的菜单（如：contextMenuStrip1）应用如下代码：
contextMenuStrip1.RenderMode=ToolStripRenderMode.Professional; contextMenuStrip1.Renderer=newToolStripProfessionalRenderer(newCustomToolStripColorTable());
ContextMenu的自定义
1.针对整个ContextMenu，自定义一个Style，去掉竖分割线
<Stylex:Key="DataGridColumnsHeaderContextMenuStyle"TargetType="{x:TypeContextMenu}">
<SetterProperty="SnapsToDevicePixels"Value="True"/>
<SetterProperty="Grid.IsSharedSizeScope"Value="true"/>
<SetterProperty="HasDropShadow"Value="True"/>
<SetterProperty="Template">
<Setter.Value>
<ControlTemplateTargetType="{x:TypeContextMenu}">
<BorderUid="Border_93">
<Border.Style>
<StyleTargetType="{x:TypeBorder}">
<SetterProperty="Tag"Value="{DynamicResource{x:StaticSystemParameters.DropShadowKey}}"/>
<Style.Triggers>
<DataTriggerBinding="{BindingTag,RelativeSource={RelativeSourceSelf}}"Value="True">
<SetterProperty="Effect">
<Setter.Value>
<DropShadowEffectBlurRadius="4"Opacity="0.8"ShadowDepth="1"/>
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</Border.Style>
<BorderBorderBrush="{TemplateBindingBorderBrush}"BorderThickness="{TemplateBindingBorderThickness}"Background="{TemplateBindingBackground}"Uid="Border_50">
<ScrollViewerCanContentScroll="True"Uid="ScrollViewer_9"
Style="{DynamicResource{ComponentResourceKeyResourceId=MenuScrollViewer,TypeInTargetAssembly={x:TypeFrameworkElement}}}">
<ItemsPresenterKeyboardNavigation.DirectionalNavigation="Cycle"SnapsToDevicePixels="{TemplateBindingSnapsToDevicePixels}"Uid="ItemsPresenter_5"/>
</ScrollViewer>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
2.针对其中的ItemContainerStyle来写个MenuItem的controltemplate
<Stylex:Key="MenuItemStyle1"TargetType="{x:TypeMenuItem}"><SetterProperty="Template"Value="{DynamicResourceMenuItemControlTemplate1}"/><SetterProperty="Margin"Value="0"></Setter><SetterProperty="Padding"Value="0"></Setter></Style><ControlTemplatex:Key="MenuItemControlTemplate1"TargetType="{x:TypeMenuItem}"><Gridx:Name="grid"SnapsToDevicePixels="True"VerticalAlignment="Stretch"HorizontalAlignment="Stretch"><ContentPresenterContentTemplate="{TemplateBindingHeaderTemplate}"Content="{TemplateBindingHeader}"Grid.Column="0"ContentStringFormat="{TemplateBindingHeaderStringFormat}"ContentSource="Header"RecognizesAccessKey="True"SnapsToDevicePixels="{TemplateBindingSnapsToDevicePixels}"/></Grid><ControlTemplate.Triggers><TriggerProperty="IsHighlighted"Value="True"><SetterProperty="Background"TargetName="grid"Value="{DynamicResourceBrush_PA_CSW_ListBoxItemDefaultHighlight}"/></Trigger><TriggerProperty="IsEnabled"Value="False"><SetterProperty="Foreground"Value="#FF9A9A9A"/></Trigger></ControlTemplate.Triggers></ControlTemplate>
3.contextMenu使用上述style
<ContextMenux:Key="DataGridColumnsHeaderContextMenu"
ItemTemplate="{DynamicResourceHeaderConfigItemTemplate}"
ItemContainerStyle="{DynamicResourceMenuItemStyle1}"
Style="{DynamicResourceDataGridColumnsHeaderContextMenuStyle}"
/>
