Binding values while or for loop

In my intuition, if I bind a value in the loop, I believed UI updates automatically.
This is my test code:

binding

private string _client1 {get; set;}
public string client1
{
    get => _client1;
    set
    {
        _client1 = value;
        RaisePropertyChanged(nameof(client1));
    }
}

Function

public async void UpdateUI()
{
    await Task.Run(() =>
    {
        DispatcherHelper.CheckBeginInvokeOnUI(async () =>
        {
            for (int i = 0; i < 10; i++)
            {
                _client1 = i.ToString();
                RaisePropertyChanged(_client1);

                await Task.Delay(200);
            }
        });
    }).ConfigureAwait(false);
}

Result
0 is shown and not changed in UI.

Expected Result
0 1 2 ... 10

I want the value to be changed continuously in UI. What is the problem with this code?

>Solution :

If the control is bound to the client1 property, then that is what you should be changing, not the backing field _client1:

client1 = i.ToString();

And since the setter for client1 already calls RaisePropertyChanged, you don’t need this line inside your loop:

RaisePropertyChanged(_client1);
