To set the content of a TextBox in WPF, you can use the Text property of the TextBox. You can set the content of the TextBox in the following way:

  1. Set up initial values in XAML.
<TextBox Text="初始值" />
  1. Set value in the code.
textBox.Text = "新的值";
  1. Utilize data binding:
<TextBox Text="{Binding PropertyName}" />

In this scenario, the content of the TextBox will be bound to the PropertyName property in the ViewModel, and any changes to the property value in the ViewModel will automatically update the content of the TextBox.

  1. Bind commands:
<TextBox Text="{Binding PropertyName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

In this scenario, the content of the TextBox will be bound to the PropertyName property in the ViewModel, so that when the TextBox content changes, the property value in the ViewModel will also be updated.

Please note that these methods can be used individually or in combination.
