WPF自定義控制元件與樣式(3)-TextBox & RichTextBox & PasswordBox樣式、水印、Label標簽、功能擴展

 原文:https://www.cnblogs.com/anding/p/4970845.html

一.前言.預覽

  申明:WPF自定義控制元件與樣式是一個系列文章,前后是有些關聯的,但大多是按照由簡到繁的順序逐步發布的等,若有不明白的地方可以參考本系列前面的文章,文末附有部分文章鏈接,

本文主要是對文本輸入控制元件進行樣式開發,及相關擴展功能開發,主要內容包括:

  • 基本文本框TextBox控制元件樣式及擴展功能,實作了樣式、水印、Label標簽、功能擴展;
  • 富文本框RichTextBox控制元件樣式;
  • 密碼輸入框PasswordBox控制元件樣式及擴展功能;

復制代碼

  模板內容主要包含四部分:

  • 用于實作Label標簽的預留區域;
  • TextBox本身的文本輸入顯示部分;
  • 水印顯示部分;
  • 功能擴展的預留區域;

  其中Label標簽、功能擴展,還有輸入框的不同狀態顯示效果都是通過附加屬性來實作的,其實從本質上附加屬性和控制元件上定義的依賴屬性是同一個概念,有些時候附加屬性會更加方便,對于一些可共用的屬性,就比較方便,這一點怎本文是有體現的,上面代碼使用到的附加屬性代碼:

2.2 水印效果實作

  通過2.1的代碼示例,可以看出,水印是內置了一個TextBlock,用附加屬性ControlAttachProperty.Watermark設定水印內容,在觸發器中檢測,當TextBox中有輸入值,則隱藏水印的TextBlock,使用示例:  

復制代碼
        <StackPanel>
            <TextBox Width="140" Height="40" Margin="3" TextWrapping="Wrap" VerticalScrollBarVisibility="Visible">333333333333333</TextBox>
            <TextBox Width="150" Height="30" Margin="3" core:ControlAttachProperty.Watermark="我是水印" core:ControlAttachProperty.CornerRadius="2"></TextBox>
            <TextBox Width="150" Height="30" Margin="3" IsReadOnly="True" core:ControlAttachProperty.CornerRadius="15" SnapsToDevicePixels="True" >我是只讀的</TextBox>
            <TextBox Width="150" Height="30" Margin="3" IsEnabled="False">IsEnabled="False"</TextBox>
            <TextBox Width="150" Height="30" core:ControlAttachProperty.Watermark="我是水印"></TextBox>
        </StackPanel>
復制代碼

  效果:

  

2.3 Label標簽實作

  參考2.1的代碼,預留了Label的區域,通過設定附加屬性local:ControlAttachProperty.Label設定標簽文本,local:ControlAttachProperty.LabelTemplate設定Label標簽的模板樣式,即可自定義實作Label標簽,自定義樣式:

復制代碼
    <!--TextBox包含附加屬性Label的樣式-->
    <Style TargetType="{x:Type TextBox}" x:Key="LabelTextBox" BasedOn="{StaticResource DefaultTextBox}">
        <Setter Property="local:ControlAttachProperty.LabelTemplate" >
            <Setter.Value>
                <ControlTemplate TargetType="ContentControl">
                    <Border Width="60" Background="{StaticResource TextLabelBackground}">
                        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Right" Margin="3" Text="{TemplateBinding Content}"></TextBlock>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
復制代碼

  使用示例及效果: 

            <TextBox Width="200" Height="30" Margin="3" core:ControlAttachProperty.Watermark="請輸入姓名" 
                         Style="{StaticResource LabelTextBox}" core:ControlAttachProperty.Label="姓名:"></TextBox>

2.4 擴展功能及自定義擴展

  思路和2.3的Label標簽實作相似,清除文本框內的內容是一個常用需求,我們就線擴展一個這么一個功能的TextBox,通過附加屬性ControlAttachProperty.AttachContent定義擴展功能的模板,模板內定義的是一個按鈕FButton(可參考上一篇,本文末尾附錄中有鏈接)  

復制代碼
    <!--TextBox包含清除Text按鈕的樣式-->
    <Style TargetType="{x:Type TextBox}" x:Key="ClearButtonTextBox" BasedOn="{StaticResource DefaultTextBox}">
        <Setter Property="local:ControlAttachProperty.AttachContent">
            <Setter.Value>
                <ControlTemplate>
                    <local:FButton FIcon="&#xe60a;" Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"
                                   local:ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" Command="local:ControlAttachProperty.ClearTextCommand" 
                                   CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"
                               Margin="1,3,1,4" FIconSize="14" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
復制代碼

  這里定義的是顯示效果,清除TextBox內容的邏輯代碼如何實作的呢?還是附加屬性:

  • ControlAttachProperty.IsClearTextButtonBehaviorEnabled="True" :注入事件到當前Button
  • Command="local:ControlAttachProperty.ClearTextCommand":定義Fbutton的命令物件實體Command
  • CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}":把TextBox作為引數傳入

  邏輯代碼如下,從代碼不難看出,它是支持多種輸入控制元件的內容清除的,也就是說該擴展功能可以輕松支持其他輸入控制元件,第四節密碼資料的清除也是這樣使用的,

  效果:

  

當然我們也可以自定義擴展其他功能,如:

            <TextBox Width="200" Height="30" Margin="3" core:ControlAttachProperty.Watermark="查詢關鍵詞" IsEnabled="True">
                <core:ControlAttachProperty.AttachContent>
                    <ControlTemplate>
                        <StackPanel Orientation="Horizontal">
                            <core:FButton FIcon="&#xe60b;"  Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"
                                            FIconSize="18" Margin="1,1,2,3" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/>
                            <core:FButton FIcon="&#xe628;"  Style="{StaticResource FButton_Transparency}" IsTabStop="False" FIconMargin="0"
                                            FIconSize="22" Foreground="{StaticResource TextForeground}" Cursor="Arrow"/>
                        </StackPanel>
                    </ControlTemplate>
                </core:ControlAttachProperty.AttachContent>
            </TextBox>

  效果:

由上不難同時實作Label標簽和清除文本內容的樣式:

            <Setter.Value>
                <ControlTemplate TargetType="ContentControl">
                    <Border Width="60" Background="{StaticResource TextLabelBackground}">
                        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Right" Margin="3" Text="{TemplateBinding Content}"></TextBlock>
                    </Border>

                               CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type TextBox}}}"
