ContextMenu 類表示當(dāng)用戶在控件或窗體的特定區(qū)域上單擊鼠標(biāo)右鍵時會顯示的快捷菜單，要想實現(xiàn)自定義的Menu和ContextMenu效果，大家可以通過派生ProfessionalColorTable類，下面小編把實現(xiàn)Menu和ContextMenu自定義風(fēng)格及ContextMenu自定義給大家整理一下

為了實現(xiàn)自定義的Menu和ContextMenu效果，下面演示代碼通過派生ProfessionalColorTable類，在自定義的類中重寫ProfessionalColorTable類的相關(guān)聯(lián)的屬性，從而實現(xiàn)自定義菜單效果。

using System.Drawing;
using System.Windows.Forms;
public class CustomToolStripColorTable : ProfessionalColorTable
{
  /// <summary>
  /// 主菜單項被點擊后，展開的下拉菜單面板的邊框
  /// </summary>
  public override Color MenuBorder
  {
    get
    {
      return Color.FromArgb(37, 37, 37);
    }
  }
  /// <summary>
  /// 鼠標(biāo)移動到菜單項（主菜單及下拉菜單）時，下拉菜單項的邊框
  /// </summary>
  public override Color MenuItemBorder
  {
    get
    {
      return Color.Transparent;
    }
  }
  #region 頂級菜單被選中背景顏色
  public override Color MenuItemSelectedGradientBegin
  {
    get
    {
      return Color.FromArgb(37, 37, 37);
    }
  }
  public override Color MenuItemSelectedGradientEnd
  {
    get
    {
      return Color.FromArgb(37, 37, 37);
    }
  }
  #endregion
  #region 頂級菜單被按下是，菜單項背景色
  public override Color MenuItemPressedGradientBegin
  {
    get
    {
      return Color.Black;
    }
  }
  public override Color MenuItemPressedGradientMiddle
  {
    get
    {
      return Color.FromArgb(37, 37, 37);
    }
  }
  public override Color MenuItemPressedGradientEnd
  {
    get
    {
      return Color.Black;
    }
  }
  #endregion
  /// <summary>
  /// 菜單項被選中時的顏色
  /// </summary>
  public override Color MenuItemSelected
  {
    get
    {
      return Color.FromArgb(37, 37, 37);
    }
  }
  #region 下拉菜單面板背景設(shè)置（不包括下拉菜單項）
  //下拉菜單面板背景一共分為2個部分，左邊為圖像區(qū)域，右側(cè)為文本區(qū)域，需要分別設(shè)置
  //ToolStripDropDownBackground設(shè)置文本部分的背景色
  public override Color ToolStripDropDownBackground
  {
    get
    {
      return Color.Black;
    }
  }
  //以ImageMarginGradient開頭的3個設(shè)置的是圖像部分的背景色，begin->end是從左到右的順序
  public override Color ImageMarginGradientBegin
  {
    get
    {
      return Color.Black;
    }
  }
  public override Color ImageMarginGradientMiddle
  {
    get
    {
      return Color.Black;
    }
  }
  public override Color ImageMarginGradientEnd
  {
    get
    {
      return Color.Black;
    }
  }
  #endregion
}

然后對需要實現(xiàn)自定義風(fēng)格的菜單（如：contextMenuStrip1）應(yīng)用如下代碼：

contextMenuStrip1.RenderMode = ToolStripRenderMode.Professional;
contextMenuStrip1.Renderer = new ToolStripProfessionalRenderer(new CustomToolStripColorTable());

ContextMenu的自定義

1.針對整個ContextMenu，自定義一個Style，去掉豎分割線

<Style x:Key="DataGridColumnsHeaderContextMenuStyle" TargetType="{x:Type ContextMenu}">
        <Setter Property="SnapsToDevicePixels" Value="True"/>
        <Setter Property="Grid.IsSharedSizeScope" Value="true"/>
        <Setter Property="HasDropShadow" Value="True"/>
        <Setter Property="Template">
          <Setter.Value>
            <ControlTemplate TargetType="{x:Type ContextMenu}">
              <Border Uid="Border_93">
                <Border.Style>
                  <Style TargetType="{x:Type Border}">
                    <Setter Property="Tag" Value="{DynamicResource {x:Static SystemParameters.DropShadowKey}}"/>
                    <Style.Triggers>
                      <DataTrigger Binding="{Binding Tag, RelativeSource={RelativeSource Self}}" Value="True">
                        <Setter Property="Effect">
                          <Setter.Value>
                            <DropShadowEffect BlurRadius="4" Opacity="0.8" ShadowDepth="1"/>
                          </Setter.Value>
                        </Setter>
                      </DataTrigger>
                    </Style.Triggers>
                  </Style>
                </Border.Style>
                <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Uid="Border_50">
                  <ScrollViewer CanContentScroll="True" Uid="ScrollViewer_9"
              Style="{DynamicResource {ComponentResourceKey ResourceId=MenuScrollViewer, TypeInTargetAssembly={x:Type FrameworkElement}}}">
                    <ItemsPresenter KeyboardNavigation.DirectionalNavigation="Cycle" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" Uid="ItemsPresenter_5"/>
                  </ScrollViewer>
                </Border>
              </Border>
            </ControlTemplate>
          </Setter.Value>
        </Setter>
      </Style>

2. 針對其中的ItemContainerStyle來寫個MenuItem的control template

<Style x:Key="MenuItemStyle1" TargetType="{x:Type MenuItem}"> <Setter Property="Template" Value="{DynamicResource MenuItemControlTemplate1}"/> <Setter Property="Margin" Value="0"></Setter> <Setter Property="Padding" Value="0"></Setter> </Style> <ControlTemplate x:Key="MenuItemControlTemplate1" TargetType="{x:Type MenuItem}"> <Grid x:Name="grid" SnapsToDevicePixels="True" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" > <ContentPresenter ContentTemplate="{TemplateBinding HeaderTemplate}" Content="{TemplateBinding Header}" Grid.Column="0" ContentStringFormat="{TemplateBinding HeaderStringFormat}" ContentSource="Header" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsHighlighted" Value="True"> <Setter Property="Background" TargetName="grid" Value="{DynamicResource Brush_PA_CSW_ListBoxItemDefaultHighlight}"/> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Foreground" Value="#FF9A9A9A"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>
3. contextMenu使用上述style
 <ContextMenu x:Key="DataGridColumnsHeaderContextMenu" 
    ItemTemplate="{DynamicResource HeaderConfigItemTemplate}" 
    ItemContainerStyle="{DynamicResource MenuItemStyle1}"
        Style="{DynamicResource DataGridColumnsHeaderContextMenuStyle}"
/>

以上就是本文通過C#實現(xiàn)Menu和ContextMenu自定義風(fēng)格及contextMenu自定義的全部內(nèi)容，希望大家喜歡。
