Loop into ListView elements

this one helps. You cannot access the cells via the ItemsSource - there you only have the items that you are displaying in your cells. The most idiomatic way to do what you want to do is to bind the color to something in your item.
You can either do that by having a property on your item that returns the correct color or by implementing your own value converter. A converter could look somewhat like this:
code :
public class TextToColorConverter: IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value switch
        {
            "value1" => Color.Black,
            "value2" => Color.Red,
            _ => Color.Blue
        };
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        // 
    }
}

wish help you to fix your issue In a virtual ListView, you cannot iterate the Items, but you can still access them by their index:
code :
for (int i = 0; i <  theVirtualListView.VirtualListSize; i++) {
    this.DoSomething(theVirtualListView.Items[i]);
}

will be helpful for those in need I want to do something like mylistview.setElementsofView(0).getElementById.setColor("black"); , The short answer to your question:
code :
is there some inherited function I can access in listview to allow me to access the elements of a particular view without a custom adapter?

Is there something like a ListView that allows dynamic relocation of ListView elements drag-and-drop style?

will help you Just intercept the Opening event of the ContextMenuStrip component (which occurs before the context menu actually appears) and do something like this:
code :
public partial class Form1 : Form {

    public Form1() {
        this.InitializeComponent();

        this.contextMenuStrip1.Opening += this.contextMenuStrip1_Opening;
    }

    private void contextMenuStrip1_Opening(object sender, CancelEventArgs e) {
        this.itemAdd.Enabled = this.listView1.SelectedItems.Count > 0;
    }

}

onTextChangedListener goes into loop, but only on first ListView element, any following elements don't loop

To fix the issue you can do Write your textchangeListener inside if (ListItem == null) { condition block, it will work.
What actually happening in your case is whenever you scroll your listview on change listener will call for each and every row that is visible.
