I’m beginner in WPF coming from WinForms.
I have searched long no success on the internet to get a working example of how to create a hidden text box.

I tried many sample codes but can’t piece together one that is complete enough to help me do this. So be patient with me as I’m floundering.

In summary I would like to get help in building a complete working sample using MVVM, Net Core 8 if it makes a difference. Of a project where the TextBox is hidden and is controlled via the MainWindowViewModel.cs. Why you’re asking, right now I just want to succeed in making the TexBox invisible as I can’t find a way to do this.

<Window x:Class="WPFTextboxvisibility.MainWindow"
    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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:WPFTextboxvisibility"
    mc:Ignorable="d"
    Title="MainWindow" Height="100" Width="200">

<Grid>
    <TextBox x:Name="txtBox" Text="I want to be invisible." HorizontalAlignment="Center" Height="28"
             Visibility="{Binding ????????}"/>

The question marks are because I believe this is the trigger in the xaml.

using CommunityToolkit.Mvvm.ComponentModel;

using CommunityToolkit.Mvvm.Input;

namespace WPFTextboxvisibility
{
public partial class MainWindowViewModel : ObservableRecipient
{

    public MainWindowViewModel()
    {

    }

}

}

Why is my MainWindowViewModel empty, because I need help.
