Bind the textbox value with values in other controls

I have a textbox whose text value I want to bind based on the values selected in two other controls.

For example, I have a ListBox and I choose a value say "Blue" and one other TextBox whose text value is say a Name - "Sam". So I want my TextBox.Text value to be like "Blue_Sam".

Is this possible?

well, if u dont want a complicated solution then u should try this---> 

private void listPicker1_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        ListPickerItem lpi = (sender as ListPicker).SelectedItem as ListPickerItem;
        var text = urTextBox.Text;        
        urTextBox.Text = lpi.Content + "_" + text; 
    }

    private void OtherTextBoxChanged(object sender, TextChangedEventArgs e)
    {
        var Othertext = (sender as TextBox).Text
        var text = urTextBox.Text;        
        urTextBox.Text = text + "_" + Othertext; 
    }

You can use MultiBinding:

<TextBox>
    <TextBox.Text>    
        <MultiBinding StringFormat="{}{0} + {1}">
            <Binding ElementName="yourComboBox" Path="SelectedText" />
            <Binding ElementName="yourTextBox" Path="Text" />
        </MultiBinding>
    </TextBox.Text>
</TextBox>
