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

<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="JavaScript method name()">
