It''s not possible to validate a HTML control usingRequiredFieldValidator
. If you want to validate your HTML control client side only then you need to use JavaScript.
RequiredFieldValidator
is used only for server controls.

您好,您可以使用javascript验证html文本框:
Hi, you can validate your html text box with javascript:
<input name="tel" id="tel" type="text" size="20" maxlength="200" style="width: 200px;" önblur="checkTelRequired(this);" /><label>*</label>
<label id="telRequired" style="display: none;">Required</label>
function checkRequired(whatYouTyped) {
var txtTel = whatYouTyped.value;
var telRequired = document.getElementById("telRequired");
if (txtTel == "") {
telRequired.style.display = "";
return false;
}
else {
telRequired.style.display = "none";
}
return true;
}
