设置文本框的Text属性（Windows Phone 8 App）

Question

Basically I want to set a textbox value equal to the CustomerName from a card which is created for Wallet. What do I need to set the text property of textbox equal to, in order to achieve this. Is this possible? Thanks

Product.xaml (Where textbox is)

The Code

<TextBoxGrid.Row="1"Grid.Column="0"Name="TodoInput2"Text="{}"Visibility="Collapsed"/>

Product.xaml.cs (Where the card for Wallet is created, I want to set my textbox equal to the value of Pi.CustomerName=member. Name )

The Code

PaymentInstrument PI;

PI = new PaymentInstrument("Account")

Pi.CustomerName = member. Name;

Answer 1

you should set PI as the datacontext for the page or for the textbox and then you can bind to it by using

<TextBoxGrid.Row="1"Grid.Column="0"Name="TodoInput2"Text="{Binding CustomerName}"Visibility="Collapsed"/>

for setting the datacontext on the textbox or in any other element you can give the element a name and in code behind set the datacontext for example

<TextBoxGrid x:Name=TxtBox>
   <TextBoxGrid.Row="1"Grid.Column="0"Name="TodoInput2"Text="{Binding CustomerName}"Visibility="Collapsed"/>
</TextBoxGrid>

in codebehind

TxtBox.DataContext=PI;
