Web Forms :: Required Field Validators Not Firing In The Page?

Feb 17, 2011

I have required field validators in my ASP.NET application form.

In the button click event of the FORM, i.e. OnClientClick(), I am calling a javascript function to validate the controls in this same page. Due to this the required field validators are not getting fired.

I need both the javascript function be fired on the button click , as well as required field validators also to work efficiently.

Web Forms :: Required Field Validators Are Being Triggered By Other Buttons On Page?

Jul 15, 2010

I have created a form with several textboxes and a dropdown list and assigned a required field validator to each of them. I also have a master page with several links to other pages, some made using <a href=..> and some linkbuttons. The problem I am having is that when I click the linkbutton links they do not redirect to the proper page, rather they trigger the validators for all textbox fields and display the validator characters next to each textbox (and the dropdown). When I fill out the form, those links redirect properly. The links created using <a href=..> do not cause this problem.

Web Forms :: Required Field Validators Not Working?

Jun 24, 2010

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.

Web Forms :: Created Some Required Field Validators And A Validation Summary Control?

Feb 24, 2011

I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.

Regular Expression And Required Field Validators Shutting Down Whole Website?

Jan 18, 2011

We are using regular expression and required field validators. They work fine, especially in out of the box environments like the log in control.

When used on other controls, e.g. a textbox, they also work, but we note that the whole site is in effect shut down until the expression is valid. I.e. the user cannot click cancel, or a link. The site only starts working again after the expression has been made valid.

How can this be fixed?

The validators should only apply to the control to validate and to the control that would cause the value of that control to be posted back to the server (e.g. a button), not the whole site.

Web Forms :: Gridview Update Not Firing With Required Field Validator?

Feb 17, 2011

I have a gridview that contains a textbox, a drop down, and a checkbox. The commandfield of the gridview has ShowEditButton="true". All of the gridview updating takes place in the "_OnRowUpdating" event. I have a Panel above the gridview with a table and some fields. Everything in the gridview works perfectly, the edit, the update etc., however, when I add a requiredfieldvalidator to the panel above the gridview, the gridview update functionality no longer works. e.g., clicking the update button does not appear to fire. If I comment out the requiredfieldvalidator, everything works fine.

Web Forms :: Field Validators Doesn't Work When Field Is Manipulated With Ajax

Sep 3, 2010

I have defined a field validator that works fine on normal behavior on a page:

<asp:RequiredFieldValidator runat="server" ErrorMessage="errroooorr" ControlToValidate="TextBoxHouseNumber" Display="Dynamic"></asp:RequiredFieldValidator>

Now if I dont insert any text in the TextBoxHouseNumber field, and push submit, the FieldValidator fires as it should. But if I now click a button that automatically fills the TextBoxHouseNumber with text from a Jquery/Ajax function, the field validator still shows. Its like "Hey, the user hasnt made any changes to the textbox, so I wont bother check it".

Web Forms :: Required Validators And Literal Text?

Jan 24, 2011

I will do my best to explain what I am trying to do. This is a form that will allow the user to change his/her password with RequiredValidators in place.Here's how to reproduce the problem that I can't seem to figure out.1. Please open up the aspx file into a browser.2. Click the "Save" button. The required validators should kick in and prompt a "Required" message.3. Key in any word in the "Change Password" textbox except for the word "pass" since I have hardcoded it into the aspx file just for example sake over here.

4. Key in anything for both the "New Password" and "Confirm New Password" textbox.5. Click the "Save" button again. You should be able to see "Your current password is incorrect." next to the "Current Password" textbox which is a Literal control.Here's the problem: How do I hide or get rid of the Literal control when I click save again? Right after the form does a post back, all the password textboxes are empty and I can't find a way to bypass the required validator controls and then screen would look like this below.I will attach my changePass.aspx file code below for reference.

Web Forms :: To Add A Required Field Validator To A Text Box On Page?

Jan 11, 2010

I need to add a Required Field Validator to a text box on my page. When I add the validator the following happens when I run the page:

When I click the submit button the page doesn't submit because the page is invalid. No error message displays despite my having set the ErronMessage. When I click inside the text box that has the Validation, then the Required error message shows. When that textbox loses focus the error message goes away. The only way I can get the page to function correctly is if I create 2 Validators for the same text box. The first validator is set to have an ErrorMessage of "" and the second one is a regular error message.

I have used these before many upon many times and never experienced this. Below you will find the Source code.

[Code]....

This code is the only way I am able to get the validation to function correctly where the ErrorMessage displays when I leave the field blank. I appreciate any help on resolving this issue. I have deleted/re-added the validation control many times. This is the only page this type of error happens on.

Web Forms :: Required Field Validator - Called From Code Behind Page?

Can a required field validator be called from the code behind page?We have several check boxes and some of them require the user to enter a date, but not all of them.(This is not a checkbox list, but individual checkboxes).Any 1 of 6 different checkboxes selected makes a txtBox visible for users to enter a date.If they don't select one of these checkBoxes which require a date - it doesn't matter, the form will still be valid.I don't think validation groups can work here so looking towards doing through .vbHere's the existing code:

Web Forms :: Validators Not Firing Off / Group Name Not Showing

Feb 4, 2010

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.

Can Manually Scroll Up To Top Of Page To See Required Field

Jan 14, 2010

I've currently got a RequiredFieldValidator added to the top 3 fields of each generated set of questions. The questions are dynamic, and what I'd love to do is pop up a red "YOU MISSED SOME FIELDS...blah blah" msg above the Submit button when the user misses those top fields. (I did do this previously with a custom validator, but I've had trouble doing this w/the dynamic fields that I've created.)Right now, if you miss a top-3 field, the page just does nothing, and the user has to manually scroll up to the top of the page to see "required field" pop up in red next to the missed field.

Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?

Apr 1, 2011

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .

I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList

<asp:DropDownList ID="DropDownList_HP" runat="server"

AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...

This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help

http://msdn.microsoft.com/en-us/library/ms366709.aspx

So I changed the ListItem in the DropDownList markup to the following:

<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"

AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...

This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.

In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.

Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

Web Forms :: Required Field Validator Not Catching Empty Field?

Feb 3, 2010

I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.

The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.

The nested ascx control is a repeater control and this may be the reason, but I am unsure.

I'm not exactly sure what question to ask, but I'll list a few below.

How do I attach the field validators up a level to the 1st ascx control?

Is it possible to put required fields into a nested ascx control?
