Reset .net Validation Control Via Javascript?
May 26, 2010
How do I reset an asp.net validation control via JavaScript? The current code sample clears the error message text but does not reset the validation control for the next form submission.
var cv= document.getElementById("<%= MyValidationContorl.ClientID %>");
cv.innerHTML = '';
Update:Here is the full code sample of the form. I can not seem to get the validation controls fire off on another form submission:
function ClearData() {
var cv = document.getElementById("<%= MyValidationContorl.ClientID %>");
cv.innerHTML = ''; [code]....

I have an ASP.NET page with a jQuery dialog that is displayed to change some data. I am setting up the jQuery dialog so that when the user clicks the OK button it calls ASP.NET's
Page_ClientValidate('validationGroup') via javascript, finds all the invalid controls and changes their CSS class. So here's the scenario: the user opens the dialog, keys in some invalid data, clicks OK (receiving the validation messages), and then clicks Cancel.
Now the dialog is closed, but the validation messages are still there, so that when they open the dialog again, the data goes back to the way it was initially, but the form is still in the invalid state (the validation messages are still displaying).
What I need is a "reset" function of sorts to call after calling Page_ClientValidate('validationGroup'). Does this exist?

I have a javascript to enable text boxes when called, I want to trigger this code when a user picks value "Custom" from a dropdownlist, so that I can display/Hide these new textboxes.
function setVisibility(DropDownListID) {
var element = document.getElementById(DropDownListID);
var element1 = document.getElementById("TestBox1");
if (element.value == "Custom") {
element1.visible = !element1.visible ;
}
<asp:DropDownList ID="DateRangeDropDownList" runat="server" Enabled="True" onChange="setVisibility('DateRangeDropDownList');">
<asp:ListItem>Some Value</asp:ListItem>
<asp:ListItem>Custom</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TestBox1" runat="server"></asp:TextBox>
For some reason it doesn't seem to work.

I'm assuming this behavior is due to the postback. I've written a little test page to demonstrate this problem.
http://cm-rosestate.mine.nu/test.aspx
There are three textboxes here, you must enter more than 2 characters for a textbox to validate. When the page loads tab into the first box and type 'abc'. Then tab into the second box and the page will validate. However, when it postbacks you'll be reset into the first textbox again. How can I accomplish a more smooth transition from one control to the next?
I have a form with about 20 textboxes on it, all of which have a customvalidator on them, and it would be much easier if the page were navigable solely by the keyboard without having to lick each textbox every time.Code is available if needed.

I have a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?

How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.

I am having some problem with Jquery validation.
In my application i am using jquery validation plugin..I am using Updatepanels and i am validating using
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(ValidateMyForm);
and ValidateMyform will validate on each button click...
var objPost = args.get_postBackElement();
if (objPost === null || objPost === undefined) return;
if (objPost.type == 'submit') {[code].....
Here I want to get back the page to normal stage(like after a full page postback)...even though after async postback the validation is still active...it should not get back to normal and its throwing errors if i enter something wrong...this is because the page is not fully refreshed on asyc postbacks...I just want get the like the normal after each asyc post back...
I tried using submit and reset to reset the page but its became to normal..the validation is still active...I have no idea what to do..

My desire is to make my normal HTML Reset button into an asp control which I can control in my seperate Code-file.I thought that giving him the attribute runat="server" would be enough, though I was mistaken.The reason why I want to have full control at him is because I have a dropdownlist that depends on another, using ajax, and when I hit the reset button, the dependent list stuck with its previous values and can't be changed again, only when I hit the reset button.

I've got a Jquery function that I wrote which blacks out the screen after a certain amount of inactivity, creates a pop-up that allows the user to click a button to stay logged in, and logs them out (closing the application window) if they do not respond in time.
The environment is ASP.NET (VB). We don't technically use master pages, but we do have a parent page in which our header, footer and nav reside, and my Jquery code is called from that window, loaded via an IFrame.My problem is that if one is working in a child window, the parent window doesn't recognize that the system is in use, and will automatically engage at the allocated time.I've tried everything under the sun I can think of and nothing works properly. My event handler is working, and it does call the parent window function, but the timer is not being reset.
I have this function in the parent window:
<script language="javascript" type="text/javascript">
function window.reportChildActivity() {
SESSION_ALIVE = true; [code]....

I have converted the change password control to a template. It is inside an update panel. After changing the password the confirm button takes the user to the success step by updating the update panel. Then by clicking the OK button, I would like to reset the password changer to its initial state so that the user can change the password again. Right now I am not sure how this is done and the control simply remains at the second step, telling the user "password has been changed" . User can press OK. What must I write in the OK button click event to reset the password control to its original state?

I am experiencing the following page error when trying to use the FileUpload control on my web page to upload files larger than 3MB or so. The error is as follows:"Problem loading page The connection was reset The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."I suspect this may be due to a timout issue. If so, how can I increase the timeout period for this control / process? I am coding in VB.NET.

I have custom control with ASP.Net validators.
writer.AddAttribute(HtmlTextWriterAttribute.Onclick, "javascript:return DoSmth();");
function DoSmth() {
var cBox = confirm("Are you sure?");
if (!cBox) {
return false;
}
else {
//Invoke validation
}
When I push button submit, I call confirm box. If I press cancel - all right. But if I press ok, I need to do validation. How can I stop postback and do valiadation?
