Web Forms :: DropDownList Validators Not Validating
Sep 7, 2010
I 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?

i have one simple question; do I have to... or is there any need to validate value from DropDownLists that are populated from SQL Datatables. I know how to validate them, but I am just concerned about potential SQL Injection, because those DropDownLists are going to be "Input fields" for a new Datatable, and insted of using TextBoxes, user will choose values from those DDL's and Submit them (INSERT INTO) to SQL Datatable. Is there a way for a "hacker" to insert his item value into DropDownList. I hop You understand what I mean!?

I 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.

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.

I 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?

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?

We are developing an Intranet application that looks up some data for a user through hooks into Active Directory. However, our Network guys don't always enter in a users email address when creating a new user. Therefore, our user database is missing the email address for over half of our users. We have over 10,000 users, therefore asking them to enter 5000+ email addresses into each missing email address field in Active Directory isn't an option. I already know how to validate that an email address is correctly formatted using Regex. What I need is a way to lookup the email address entered in the email address textbox and see if it exists on Outlook/Exchange (or looking up the email address using the First Name/LastName would work). If it does exist then the address is valid, if it is invalid then the user typed in the wrong address. I've tried to do something with CDO, but have had no luck. We use Outlook 2003 and ASP.NET 2.0.

I have 2 textboxes in my page. One is supposed to hold the Date and the other Time. These 2 data are merged when saving into one database field having a datetime datatype. Upon retrieve, the datetime field value is split into 2 and put into the Date Textbox and Time TextBox.
Upon input, when I am trying to update, the validator always says "Invalid Time."

I 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? Will 'Mark As Answer' for replies leading to a solution.

I'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:
[Code]....
End result? No validation. So what's the move?

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.

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.
