Event on label is not updating the clicked label

I want to add a event for label when a specific label is pressed, but my event handler is not reacting to the clicked label.

I created a calender so when I click a date I want to highlight that date, that's the requirement.

for (Int32 i = 1; i <= Dayz; i++)
{
    ndayz += 1;
    lblDayz = new Label();
    lblDayz.Text = i.ToString();
    lblDayz.Cursor = Cursors.Hand;
    lblDayz.Name = "Date" + i;
    lblDayz.Anchor = AnchorStyles.None;
    lblDayz.TextAlign = ContentAlignment.MiddleCenter;

    lblDayz.Click += lblDayz_Click;
}

Event handler looks like:

public void lblDayz_Click(object sender, EventArgs e)
{
    lblDayz.BackColor = Color.FromArgb(176, 180, 43);
    lblDayz.ForeColor = Color.White;
}

Your current implementation is trying to change the properties of lblDayz, which might be a single label somewhere. But the way you're creating labels you have a number of labels generated in code. One for each day

That means you need your handler to react to the label that was clicked. The label that was clicked is the sender in your event handler. Crudely then you could handle it like this

public void lblDayz_Click(object sender, EventArgs e)
{
    Label clickedLabel = sender as Label; 

    clickedLabel.BackColor = Color.FromArgb(176, 180, 43);
    clickedLabel.ForeColor = Color.White;
}
