I am using required field validator for controls.In one scenario iam not showing one textbox so when I click on button validation is firing so I can I do this to not fire validation when the textbox is in hide?
View 1 RepliesIf a control is disabled (enabled = false), will the validator controls associated with it automatically know not to carry out validation?i have a checkbox and a textbox, if the checkbox is checked, the textbox is enabled, and has to have a value, where i used a required field validator.but if the checkbox is not checked, textbox is then disabled, however, the validator controls still seem to be trying to validate the disabled textbox.so is there a way to disable validator according to textbox's state? such as textbox.enable = true? seems like causevalidation method requires multiple button, owever i only need one...

I've set up a page that uses JavaScript to hide or show rows in an HTML table, depending on the state of a checkbox.
So far, so good. But this is a data entry form and some rows include validation controls. However, it appears that if I hide a row (using JavaScript: style.display = 'none') that contains a validation control, the control still validates on an attempt to postback.
way I can do this but have the validation controls not do anything if that row is hidden?
I have been looking on the internet but don't seem to be able to find the answer. I am wondering is there a way to disable a validator on both the client and server side depending on the value of another control.
The situation is that I have a radiobutton that hides a textbox depending on the radionbuttonlist selected value . So I want to disable a validator on both server and clientside if the value selected is "N".
I have a dropdown list for the which values are coming from DB. There is one option name OTHER, when I select other the textbox appears. For that Textbox I have made a required field validator. Till here it works fine. But when I select any other option, still it gives me validator errors. It should not happen. It should only give me required field error when the user doesn't fills the textbox on select of OTHER option. Please see the code.
Dropdown and Textbox code:-
<asp:DropDownList ID="ddlGraduation" runat="server" CssClass="txtfld-popup_drp"></asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqGraduation" runat="server" ControlToValidate="ddlGraduation"
ErrorMessage="Please select graduation details" InitialValue="--Select--" SetFocusOnError="true"></asp:RequiredFieldValidator>
<asp:TextBox ID="txtOther" runat="server" CssClass="txtfld-popup_p"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqOther" runat="server" ControlToValidate="txtOther" ErrorMessage="Please specify your qualification"></asp:RequiredFieldValidator>
JS code for hiding and show the textbox when user select and deselect the OTHER option from dropdown list:-
<script language="javascript" type="text/javascript">
function pageLoad() {
$('#ctl00_ContentPlaceHolder1_txtOther').hide();
$('#ctl00_ContentPlaceHolder1_ddlGraduation').change(function () {
if ($(this).val() === "Other") {
[Code] .....
How to achieve this...
my question is very simple. I had read through many post include this: http://blog.anasghanem.com/post/How-to-get-the-readonly-textbox-value-on-the-server-.aspxI have a calender extender and the date was target to a texbox. This textbox, i had set it to readonly and it is validate by a required field validator. so mean this texbox must have a value inside. my prob is, i bind the textbox to database and if data is NULL or empty i can't save it because the required field validator was validate textbox as empty value at cllient side. If i remove the required field validator everthing fine. But this is not i want. I have try to set the textbox to javascript onCopy,onPaste,onkeyup. but user also can delete and paste into the textbox.i have think to disable the requried field validtor at server side when data is inserted.
View 16 RepliesIn my web page I have a Checkbox (datatype = tinyint/boolean) and 2 Required field validator (whose visibility is false). I want that when I check(tick) the checkbox, then required field validator visible = true, else not.For this I tried this code on Page_Load as well as on save button click, but it is not working:
protected void Page_Load(object sender, EventArgs e) {
if (ChkComplexPass.Checked) {
Regex4.Visible = true;
Regex.Visible = true;

I want to disable a ASP.NET RequiredFieldValidator with JavaScript. Actually I'm using the following code:
function doSomething()
{
var myVal = document.getElementById('myValidatorClientID');
ValidatorEnable(myVal, false);
}
This disables the validator. But my problem is, that I'm using a ValidationSummary. And this summary shows the validation message, even if I disable the validator.
how to disable the validator in the ValidationSummary too?
I have the need to remove my custom field validators on the clientside based on certain conditions
View 1 Repliestrying to set up a form where the user has to either fill out a textbox or check the check box provided. is the a way around the Required field validator as as far as i know it can only work with one item to validate. Not been doing asp for long so not sure on what other options there are.
i need to check , client side, if both email and phone number are empty .The textboxes are template columns of a detailview. I've added a custom validator for each textbox (one inside edit template, one inside insert template, etc . . ) each custom validator call the same javascript function . So the problem is : the custom valiator is activated only when at least a charachter is put into a textbox and i want to check if both textbox are empty .
View 3 RepliesI have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
imgLV.Attributes.Add("onclick", "document.getElementById('ctl00$MainHeaderContent$txtType').value='LV';return true;");
imgGV.Attributes.Add("onclick", "document.getElementById(('ctl00$MainHeaderContent$txtType')).value='GV';return true;");
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden();
t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType");
if (t.Value=="GV") {
assign one template}
else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.
I'm having a registration form with textboxes that have more than one validator, e.g. a requiredfieldvalidator and a comparevalidator. I want the error message to show up on the right side of the textbox, but because I use more than one error message, one of them is not neatly next to the textbox, but further away from it.
View 2 RepliesI have a couple of textboxes (actually a set of pairs of textboxes) where users can either enter a value or a percentage of a value but cannot use both. So in any given time some of these textboxes are disabled depending on which option the user chose.
For the textboxes representing percentages, there is a range validator to make sure only values from 0 to 100 are entered. If user selectes to enter datanot in percentage form, the percentage textbox gets filled automatically based on the value user enters. So if the total is something like 8 and user enters 2, the corresponding percentage textbox gets filled with 25% (minus the % sign).
However, the vaidation fails as if there is nothing there, persumably because the textbox is disabled. How do I get around this?

I have a form that contains several textboxes and each one paired with a required validator. Each box reads a value from a dataset, and on submit click, update the database with the new value. For some reason, one of the validator always returns the error message even if I enter a value in the textbox. My code is something like this.

I've been working on a task to add a validator to compare the values of two text fields in a ASP.NET 1.1 application.
It uses validators already, so the best approached seemed to involve a CustomValidator. I was inspired by the following example:

I got the server side validation working - now I'm trying to add some client-side validation but I'm having a strange issue.
When I click in either of the two text fields, the value of the txtFinalGrade field is overridden to either "true" or "false". I've been having a tough time tracking down the code that's causing this. I tried using the IE Developer Toolbar to trace the script - as well as FireBug in Firefox (though this is an IE-only app) and I'm still trying to figure out what's causing this to happen.
Since I think this is a JavaScript issue, I'm posting that part of my code:
