Their is nothing as "KeyPress" server side Event for Asp.Net TextBox. You may call your JavaScript function on OnTextChanged Event using ClientScript.RegisterStartupScript.

C#

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
   string eValue = "Something";
   decimal decimalValue = 100;
            
   ClientScript.RegisterStartupScript(this.GetType(), "MyScript",  "javascript:numbersonly(" + eValue + "," + decimalValue.ToString() + ")", true);

}

Have a look at below link for more information on OnTextChanged Event.
