假设我有一个项目控件绑定到VM上的项目列表.datatemplate内部是一个文本框.如何将焦点设置为XAML或VM中的第一个文本框？

在此先感谢您的帮助!

<ItemsControl ItemsSource="{Binding UsageItems}" Grid.Row="1" Focusable="False">
<ItemsControl.ItemTemplate>
    <DataTemplate>
            <Grid Margin="0,0,0,3">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="100"/>
                <ColumnDefinition Width="10"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="10"/>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="10"/>
                <ColumnDefinition Width="Auto"/>
            </Grid.ColumnDefinitions>

            <TextBlock Text="{Binding Month}" Style="{StaticResource Local_MonthLabel}" />
            <core:NumericTextBox Value="{Binding Actual, Mode=OneWay}" Style="{StaticResource Local_ActualUsageEntry}" Grid.Column="2"/>

            <core:ValidationControl Instance="{Binding Model}" Grid.Column="4" PropertyName="{Binding MonthNumber, StringFormat=AdjustedUsage{0}}">
                <core:NumericTextBox Value="{Binding Adjusted}"  DefaultValueIfNull="0" Style="{StaticResource Local_AdjustUsageEntry}" x:Name="AdjustmentEntry" inventoryLocationSetup:InitialFocusBehavior.Focus="True" />
            </core:ValidationControl>

            <telerik:RadComboBox ItemsSource="{Binding Converter={StaticResource Converter_EnumToEnumMemberViewModel}, Mode=OneTime, Source={x:Type Enums:UsageAdjustmentTypes}}" SelectedValue="{Binding Code, Mode=TwoWay}" Grid.Column="6" Style="{StaticResource Local_CodeSelector}"/>

        </Grid>
    </DataTemplate>
</ItemsControl.ItemTemplate>
