Hello @sanket if you want to see remaning word in textbox then you can use this method:
private void textBox1_TextChanged(object sender, EventArgs e)
        {
            label1.Text = (500 - textBox1.Text.Length).ToString();
        }

for this you can use text changed property of textbox

Dear Snaket Jain,


If you set maximum lenght of your Textbox.you must not change the text property.you will increase your charter length.
