Question

我正在开发WPF应用程序；我的问题是当我最大化窗口并在其最小化/调整大小之后；该控件在最大化上运行良好，但是当我最小化/调整窗口大小时，控件（文本块，组合框）不保持最大尺寸。我怎样才能使控件的大小最小化？

以下是我的XAML代码的一个示例：

<UserControl x:Class="MyNamespace.UC.Suppliers_Insert"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

         mc:Ignorable="d" 
         d:DesignHeight="450" d:DesignWidth="800">
 <DockPanel Name="MainDock" LastChildFill="True" DataContext="{Binding Suppliers_Insert, Source={StaticResource Locator}}" 
           VerticalAlignment="Stretch" 
           Height="Auto">
    <Grid>
        <Grid>

谢谢。

编辑： 我忘记指出UC已进入MainView的StackPanel中。我将SP更改为Grid，现在，当窗口最小化时，内容将正确调整大小。

我对您的usercontrol进行了调试，为此，我必须删除xaml中使用的命令和样式。我可以看到控件在窗口调整大小上达到最小或最大化。我确定问题出在您应用于控件的样式上。我使用的代码是：

 <DockPanel Name="MainDock" LastChildFill="True" 
           VerticalAlignment="Stretch" 
           Height="Auto">
        <Grid>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Name="wRow0" Height="*"/>
                    <RowDefinition Name="wRow1" Height="*"/>
                    <RowDefinition Name="wRow2" Height="*"/>
                    <RowDefinition Name="wRow3" Height="*"/>
                    <RowDefinition Name="wRow4" Height="*"/>
                </Grid.RowDefinitions>

                <telerik:RadWatermarkTextBox Grid.Column="0" Grid.Row="0" WatermarkContent="Supplier Name" Text="{Binding SupplierModel.Supplier_Name, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" 
                                          Margin="5,5,5,0" Visibility="{Binding Supplier_Name_Visibility}" IsEnabled="{Binding Supplier_Fields_Enable}"
                                         />

                <telerik:RadWatermarkTextBox Grid.Column="0" Grid.Row="1" WatermarkContent="Vat Number" Text="{Binding SupplierModel.VAT_Number, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" 
                                          Margin="5,5,5,0" Visibility="{Binding VAT_Number_Visibility}" IsEnabled="{Binding Supplier_Fields_Enable}"
                                         />

                <telerik:RadWatermarkTextBox Grid.Column="0" Grid.Row="2" WatermarkContent="Tax Code" Text="{Binding SupplierModel.Tax_Code, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" 
                                         Margin="5,5,5,0" Visibility="{Binding Tax_Code_Visibility}" IsEnabled="{Binding Supplier_Fields_Enable}"
                                         />

                <telerik:RadWatermarkTextBox Grid.Column="0" Grid.Row="3" WatermarkContent="External Supplier ID" Text="{Binding SupplierModel.External_Supplier_ID, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" 
                                         Margin="5,5,5,0"
                />

                <telerik:RadWatermarkTextBox Grid.Column="1" Grid.Row="0" Grid.ColumnSpan="2" Grid.RowSpan="3" WatermarkContent="Note" AcceptsReturn="True" Text="{Binding SupplierModel.Note, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" 
                                         Margin="5,5,5,0" 
                />

                <telerik:RadWatermarkTextBox Grid.Column="1" Grid.Row="1" Grid.ColumnSpan="2" WatermarkContent="Website" Text="{Binding SupplierModel.Website, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" 
                                          Margin="5,5,5,0"  
                                         />


                <telerik:RadButton x:Name="rdb_Insert" Grid.Row="3" Grid.Column="3" HorizontalAlignment="Right" Margin="10,0,10,0" VerticalAlignment="Center"   Width="75" 
                                />
                <telerik:RadButton x:Name="rdb_Cancel" Grid.Row="4" Grid.Column="3" HorizontalAlignment="Right" Margin="10,0,10,0" VerticalAlignment="Center"  Width="75" 
                               />
                <telerik:RadButton x:Name="rdb_Close" Grid.Row="4" Grid.Column="3" HorizontalAlignment="Right" Margin="10,0,10,0" VerticalAlignment="Center" 
                                   Width="75"  />
            </Grid>
        </Grid>
    </DockPanel>

最小化后，WPF应用程序控件不会调整大小
