Hi,@Partha Mandayam . Welcome Microsoft Q&A.
If your field is assignment, you could refer to the code below.

MainWindow.xaml:

<Grid>  
        <TabControl >  
            <TabItem Header="Tab1">  
                <Grid Background="AliceBlue">  
                    <Button x:Name="btn" Width="100" Height="50" Click="btn_Click"  Content="tab1"/>  
                </Grid>  
            </TabItem>  
             
            <TabItem Header="Tab3">  
                <Grid Background="#FFE5E5E5">  
                    <Grid.ColumnDefinitions>  
                        <ColumnDefinition Width="67"/>  
                        <ColumnDefinition Width="330*"/>  
                    </Grid.ColumnDefinitions>  
                    <TextBox x:Name="tb1" Text="hello" Width="200" Background="AliceBlue" Height="50"  />  
                    <TextBox x:Name="tb2" Grid.Column="1" Text="hi" Width="200" Background="AliceBlue" Height="50"/>  
                </Grid>  
            </TabItem>  
        </TabControl>  
  
    </Grid>  

MainWindow.xaml.cs:

private void btn_Click(object sender, RoutedEventArgs e)  
        {  
            tb2.Text = "ok";  
        }
