I have added the validations dynamically on my page.But Page is not working fine for me as its always returns true? How to fix this for dynamic validations?
my problem is that i have a dynamic controls(text boxes) that are generated depending on a dropdownlist
and upon generating the textboxes i have created a required field validator and associated it to the text box that is being generated,
when javascript is enabled in my browser, the client side validation works fine, but when i disable the javascript.. no server side validation occurs and the Page.IsValid gives true when the method Page.validate() is fired
i tried a new simple page with dynamic controls and seems to work fine, but i could not figure out whats wrong with this page.
private void generateFarmForm()
{
int numberOfFields = 9;
Label[] labels = new Label[numberOfFields];
TextBox[] farmt = new TextBox[numberOfFields];
[Code]....
also the button that submits the form back has the same validation group,,, yet no luck with this... the page is in a content tag of a master page if this has any relation to the problem
Please correct me if I am wrong, or agree with me if I am right.
1. Validator.Enabled == false;
2. Before Page.Validate(groupName) is called, BaseValidator.Validate() is called.
3. If a Validator is not being displayed, such as being in an non active View of a MultiView.I even wrote a Custom Validator that was in View.It checked if Validator.IsValid and it returned true when it wasn't.Is there any way to get around number 3?
I have a contact page with fields like E-mail Address, Name, Subject, and Message. I use a RequiredFieldValidator on each text box. They work fine when I test it with the Visual Studio built-in development server, but on IIS7, they don't work and they allow the Send button's click event to be fired.
View 6 RepliesI have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.
View 2 RepliesI've used the AJAX Slideshow Extender to create a very bare bones slideshow on the default page of my website. I have created a page function that returns an array of AjaxControlToolkit.Slide. When I manually create the array of slides, the slideshow works. However, when I use a LINQ query to build the array, the Slideshow doesn't display slides. I don't know what could be going wrong here, as there are no errors listed by Visual Studio, and the page itself loads without any reported error. Here is my code-behind. (From Devault.aspx.vb:

I have a page with GridView, one of templates of which is ascx page used like Field Template. This ascx page has a button to add some data to page, but by pressing this button "MaintainScrollPositionOnPostback" not working with main page.
Tried rather much from web, but still no result.
the buttons are created fine, when i click a button i get my javascript alert, but my labels arent updated, its like the serverside function isnt running it at all
the "SetTemplateContent" section the aspx section is at the bottom if that helps

I have a placeholder to which I programmatically add DataGrids... In the DataGrids, I programmatically add TextBoxes along with dynamic validations. Somehow, the DataGrids show up, but the dynamic validations don't work. If I set them to static, the blank space for them appears, but still, they wont work.

I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.
In the template field i am creating a dynamic javascript on RowDataBound.
I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.
I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.
I have a site when the customers can add their own style rules to their websites. The whole process works perfectly, but when they page with the dynamic stylesheet posts back, sometimes only some of the stylesheet rules load. The initial page loads all of the styles, and some postbacks it loads fine as well, but on some of the postbacks (about 60%) certain styles randomly get dropped. Is it a lifecycle issue? Its so random, I have nothing to trace. Is there a way to load the dynamically generated stylesheet and persist it throughout the session, then dismiss it?

I recently ran into some strange problems. Changes to files that are not code-behind (and not gets compiled to a DLL) should not require you to recompile the whole website, and this has never been I problem for me. These should actually get compiled dynamically when you first access the resource, e.g. the first time when browsing an updated aspx-page in the browser.
But yesterday, during development of a website, I noticed that even the smallest changes in html, javascript or anything in the .aspx-files doesn't get reflected when I save and reload the page in my browser. Rebuilding doesn't help either, actually I'll have to do a "Rebuild All" (in Visual Studio 2008) in order to see the changes. This applies to all aspx-files in my project.
I tried with minor changes on files in another web application project on the same server, and there it works as it should. Something must has happened to this particular application, but I cannot figure out what. Do you have any ideas on how to solve this?

I recently upgraded my web app to .net 4 and was surprised to see that the validator controls are no longer red. People are calling up all confused because they can't see the error messages now.Any idea how to fix this in one go? I know I can do a kludge like forecolor=red on every single validator control, but that's ugly. I don't want to go back to <pages controlRenderingCompatabilityVersion="3.5" /> because it's time to move forward, but I do want validator controls people can actually see.
View 2 RepliesI can't seem to get any sort of validator to fire when validating my DropDownList. I just want to make sure that it isn't left at "--Select--" when the user presses the Add button on the page. I've tried a range validator and required field validator and neither seem to fire at all. My DropDownList contains ID which is an int that is hidden and Name which is a string that is displayed. The ID is -1 for "--Select--". I use these all the time and can't understand why the page in this new solution is any different from other solutions I have done in the past. What have I missed?
View 18 RepliesI have a login web form with two textboxes for user name and pasword. The textboxes has a validator each and when I press the Login button everything is OK. I also have a second button which is used to redirect to a page for non logged in users. When I press that buon the form validators stops me from redirecting. How can I "use" validators for only one button and not the other?
View 5 RepliesI have a webform that contains a few textboxes with required field validators and a gridview. I'm trying to add an edit function to the gridview, but when I go to update the textbox validators fire. Is there someway to trap the edit event and disable the rfvs?

View 1 RepliesI'm attempting to create a custom control that extends the Table class. Inside of the table will be rendered a number of different controls based on a specified identifying property. On some of these controls, however, I need to specify validation for data types and requirement. To me, the most logical way of doing so is to add validators to the table and set their appropriate properties to specify which controls to validate. In doing so, however, I've discovered that none of the validators added will even render on the page in which the control is added. So is this a valid construct?
Here's an example of what I mean:

End result? No validation. So what's the move?
I am using two custom validator to validate EMAIL (should not be reused) & a captca image (text).Everything is working fine except that the displayed are not dynamic even though I set the displaystatus as DYNAMIC.

1. Enter email already registered
2. Enter invalid captcha text
both displays error. fine for now. but again.
1. Enter email NOT registered
2. Enter invalid captcha text
the error message at the email is still displayed as 'the email is arlready registered'. How can I remove the message for the email?
I have a complex page with many validators on it. When I first hit the page, if I do a postback, all the validators fire off. If I enter like half of the textbox values and then try to go to the next page, it will stop me from going to the next page, but the red text errormessage does not show up. What am I doing wrong?
[code]....
In this instance, when I first hit the page, and try to go next, it will say: "Please enter Group Name."
If I fill in a few textboxes and then try to go next, it will not allow me to go next, but the text: "Please enter Group Name." does not show.
im currently doing a web application.
user are allow to insert some events.
but if user didnt insert any fields, error message should pop out.
