I want to run whatever client-side validation routine is hooked up to a particular text input element.
The validation has been set up using CustomValidator
:
<asp:textbox id="AddEstTime" runat="server" Width="55px"></asp:textbox><br />
<asp:CustomValidator ID="AddEstTimeCustomValidator" ClientValidationFunction="AddEstTimeCustomValidator_ClientValidate" OnServerValidate="AddEstTimeCustomValidator_ServerValidate" ErrorMessage="Please enter a time" ControlToValidate="AddEstTime" runat="server" Display="Dynamic" ValidateEmptyText="true"/>
<asp:CheckBox ID="AddIsTM" runat="server" Text="T&M" />
and the javascript:
function AddEstTimeCustomValidator_ClientValidate(sender, args) {
var checkbox = $("input[id$='IsTM']");
args.IsValid = checkbox.is(":checked") || args.Value.match(/^\d+$/);
}
When the CheckBox
"AddIsTM" state changes, I want to revalidate the textbox
"AddEstTime", using its hooked-up CustomValidator
"AddEstTimeCustomValidator".
I am aware of focus -> add a character refocus -> remove character. I am trying to find a more correct way. New to asp.NET.
After looking through the Microsoft client-side code, I came up with this which seems to work:
// client-side validation of one user-control.
// pass in jquery object with the validation control
function ValidateOneElement(passedValidator) {
if (typeof (Page_Validators) == "undefined") {
return;
}
$.each(Page_Validators, function (index, value) {
if ($(value).attr("id") == passedValidator.attr("id")) {
ValidatorValidate(value, null, null);
}
});
}
This was after examining the Page_ClientValidate
function:
function Page_ClientValidate(validationGroup) {
Page_InvalidControlToBeFocused = null;
if (typeof(Page_Validators) == "undefined") {
return true;
}
var i;
for (i = 0; i < Page_Validators.length; i++) {
ValidatorValidate(Page_Validators[i], validationGroup, null);
}
ValidatorUpdateIsValid();
ValidationSummaryOnSubmit(validationGroup);
Page_BlockSubmit = !Page_IsValid;
return Page_IsValid;
}

i just ran the simplest JS
Page_ClientValidate();
if you have a validation group then is
Page_ClientValidate("validationGroupName")
