How to implement Binding in UserControl?

Question

WPF

I created a UserControl, now I can use it in MainWindow.xaml:

<local:UserControl1 Margin="731,757,10,232" Height="40" />

Tell me how to transfer when using UserControl1 in MainWindow.xaml?:
1. Text in TextBlock
2. Event MouseLeftButtonDown = "MouseLeftButtonDown"

usercontrol

<UserControl x:Class="Boots.UserControl1"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:Boots"

    <local:MyGrid x:Name="Objx" HorizontalAlignment="Left" VerticalAlignment="Top" >
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="80" />
            <ColumnDefinition Width="40" />
            <ColumnDefinition Width="40" />

            <ColumnDefinition Width="200" />
            <ColumnDefinition Width="40" />
            <ColumnDefinition Width="40" />
         </Grid.ColumnDefinitions>

        <TextBlock  Grid.Column="0" Grid.Row="0" Margin="1" Text="" HorizontalAlignment="Center" VerticalAlignment="Center"  />

        <local:Cell Grid.Column="1" Grid.Row="0" Content="" />
        <local:Cell Grid.Column="2" Grid.Row="0" Content="" />

        <TextBox Grid.Column="3" Grid.Row="0" Margin="10"/>

        <local:Cell Grid.Column="4" Grid.Row="0" Content=""  />
        <local:Cell Grid.Column="5" Grid.Row="0" Content=""  />
