<DockPanel>
        <Grid DockPanel.Dock="Left" Height="426">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>

        </Grid>
        <DockPanel>
            <Grid DockPanel.Dock="Left" Height="406">
                <Grid.RowDefinitions>
                    <RowDefinition Height="372"></RowDefinition>

                    <RowDefinition Height="7"/>
                    <RowDefinition Height="27*" />
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="200"></ColumnDefinition>
                </Grid.ColumnDefinitions>
                <Border CornerRadius="6" BorderBrush="Purple" BorderThickness="3" Margin="18,8,0,7" Grid.RowSpan="2" Width="182">
                    <Image Grid.Row="1" Name="messageImage" Height="359" Width="177"></Image>
                </Border>
                <Button Name="ChangeImagebtn" Background="white" Content="Change Image" Grid.Row="2" Margin="21,2,0,-2" Click="ChangeImagebtn_Click"></Button>
            </Grid>
        </DockPanel>

    </DockPanel>

当我运行程序时，出于某种原因选择了保存按钮，我不希望它出现。在此先感谢您的帮助

我认为第一个按钮是被选中的按钮 - 但我可能错了。

您可以通过将另一个按钮的IsDefault属性设置为true来指定您想要成为默认按钮的按钮。

如果要将焦点设置为文本框，则可以使用：

FocusManager.FocusedElement="{Binding ElementName=myTextBox}"

Window定义中的
