Validated and KeyPress events

I notice ASP is missing the Validated and Keypress events. I used the keypress event in my windows app to only allow numbers to be entered in some of my text boxes. I used the Validated event to check for specific formats using regular expressions. Is there an equivelent built into ASP?

you have to use javascript

Code:

---

<input type="text"
onKeyPress = "jsMethod(this);"
onBlur = "jsFormat(this);"></input>

---

alternatly for a server control setup the js on the server through

Code:

---

ctl.Attributes["onKeyPress"] = "jsMethod();";

---

or something like that
