如何在TabItem（WPF）中自動調整網格控件的大小？

[英]How to auto resize grid control in a TabItem (WPF)?

問題描述

我有一個TabControl ，並在其中一個TabItem中放置了一個文本框，其定義為Margin="0" 。

現在，此文本框直接取決於網格的大小，並將隨網格調整大小。 但是，我找不到如何在TabItem中自動調整網格大小的方法。

基本上，我希望TabControl及其中的所有元素自動調整大小。 選項卡控件會自動正確調整大小，如果元素不在TabControl內部，則所有元素都會自動正確調整大小。

當Tab控件自動調整大小時，如何使TabControl中的元素調整大小？

任何幫助或建議都是有用的。

這是我的xaml： 

<TabControl x:Name="tabControl" Margin="8,28,8,8">
  <TabItem x:Name="tabItem" Header="Send">
    <Grid Width="200" Height="200">
      <TextBox x:Name="textBox" Margin="0,0,0,0"/>
    </Grid>
  </TabItem>
</TabControl>

如您所見，如果增加網格的寬度和高度，則文本框的大小將增加，但是隨着tabItem和tabControl的增加，我將無法增加網格。

從網格中刪除寬度和高度，您可以自動調整大小；-) 

<TabControl x:Name="tabControl" Margin="8,28,8,8">
  <TabItem x:Name="tabItem" Header="Send">
    <Grid>
      <TextBox x:Name="textBox" Margin="0"/>
    </Grid>
  </TabItem>
</TabControl>

編輯

一旦我理解了問題，這就是我建議的解決方案。

這是取自Kaxaml的樣式（稍作修改） 

<Style  TargetType="{x:Type TabControl}">
  <Setter Property="OverridesDefaultStyle" Value="True" />
  <Setter Property="SnapsToDevicePixels" Value="True" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabControl}">
        <Grid KeyboardNavigation.TabNavigation="Local">
            <Grid.ColumnDefinitions>
              <ColumnDefinition Width="Auto"/> <!-- first modify, use Auto instead * -->
            </Grid.ColumnDefinitions>
          <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="Auto"/> <!-- second modify, use Auto instead * -->
          </Grid.RowDefinitions>
          <TabPanel 
            Name="HeaderPanel"
            Grid.Row="0"
            Panel.ZIndex="1" 
            Margin="0,0,4,-1" 
            IsItemsHost="True"
            KeyboardNavigation.TabIndex="1"
            Background="Transparent" />
          <Border
            Name="Border" 
            Grid.Row="1" 
            Background="#FFFFFF" 
            BorderBrush="#888888" 
            BorderThickness="1" 
            CornerRadius="2" 
            KeyboardNavigation.TabNavigation="Local"
            KeyboardNavigation.DirectionalNavigation="Contained"
            KeyboardNavigation.TabIndex="2" >
            <ContentPresenter
              Name="PART_SelectedContentHost"
              Margin="4"
              ContentSource="SelectedContent" />
          </Border>
        </Grid>
        <ControlTemplate.Triggers>
          <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Foreground" Value="#888888" />
            <Setter TargetName="Border" Property="BorderBrush" Value="#AAAAAA" />
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

<!-- SimpleStyles: TabItem -->

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
        <Border 
          Name="Border"
          Margin="0,0,-4,0" 
          Background="#E0E0E0"
          BorderBrush="#888888" 
          BorderThickness="1,1,1,1" 
          CornerRadius="2,12,0,0" >
          <ContentPresenter x:Name="ContentSite"
            VerticalAlignment="Center"
            HorizontalAlignment="Center"
            ContentSource="Header"
            Margin="12,2,12,2"
            RecognizesAccessKey="True"/>
        </Border>
        </Grid>
        <ControlTemplate.Triggers>
          <Trigger Property="IsSelected" Value="True">
            <Setter Property="Panel.ZIndex" Value="100" />
            <Setter TargetName="Border" Property="Background" Value="#FFFFFF" />
            <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
          </Trigger>
          <Trigger Property="IsEnabled" Value="False">
            <Setter TargetName="Border" Property="Background" Value="#EEEEEE" />
            <Setter TargetName="Border" Property="BorderBrush" Value="#AAAAAA" />
            <Setter Property="Foreground" Value="#888888" />
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

根據您的風格進行更改 

<Grid.ColumnDefinitions>
  <ColumnDefinition x:Name="ColumnDefinition0" Width="Auto" />
  <ColumnDefinition x:Name="ColumnDefinition1" Width="0" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
  <RowDefinition Height="Auto" x:Name="RowDefinition0" />
  <RowDefinition Height="Auto" x:Name="RowDefinition1" />
</Grid.RowDefinitions>

希望這可以幫助。
