C# loss of focus on textbox

I already set a standard text and color for the text and when the textbox is clicked I clear the text for the User type text and define color black. on click event:

 if (txtbox.Text == "Ex.: [text test]")
            {
                txtbox.Text = string.Empty;
                txtbox.ForeColor = Color.Black;
            }

I want to set a default text if the textbox is empty and the focus is in another textbox, so if the User clicking or pressing tab.

  private void textBox1_Validating(object sender, EventArgs e)
    {
        if (string.IsNullOrWhiteSpace(textBox1.Text))
        {
            //Your logic here or the color you want 
        }
    }

Please, write the below code in both click and keypress event function (for working of tab)

If(txtbox.Text == "")
{
    txtbox.Text = "Default";
    txtbox1.focus();  //focus will be set to another textbox.
}

If there are two textboxes txt1 and txt2 on form form1 then

form1_Load(object sender, System.EventArgs e)
{
    txt2.SetFocus;
    txt1.text = "Default Text";
}
txt1_Click(object sender, System.EventArgs e)
{
    if(txt1.text == "Default Text")
    {
        txt1.text = "";
    }
}
txt1_Leave(object sender, System.EventArgs e)
{
   if(txt1.text == "")
   {
        txt1.text = "Default Text";
   }
}

I think it would work.Let me know if any error occurs.

You could set your default text in the Leave event. This will run any time the text box looses focus. 

    private void textBox1_Leave(object sender, EventArgs e)
    {
        if (textBox1.Text == String.Empty)
        {
            //Set default text here.  
        }
    }
