Web Forms :: Dropdown Validation Not Working When Add Validation Control In Code Behind
Mar 19, 2010
I am creating dropdown controls in code behind. in some conditions I need to add validation control to dropdowlist. But Validation not firing when I submit button.
If mQuestion.RequiredToAnswer = True Then
Dim mValidator As New RequiredFieldValidator
mValidator.ControlToValidate = mDDL.ID
mValidator.InitialValue = mDDL.Items(0).Text
mValidator.Display = ValidatorDisplay.Dynamic
mValidator.ErrorMessage = "* Required!"
mTableCell.Controls.Add(mValidator)
End If
I have other dropdown controls on aspx page with validation comtrols. Those are working fine. Only when I ddl and validations from code not working?

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.

jQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.

In my Website I have header control (header.ascx) and footer control (footer.ascx).In header.ascx one textbox and one button is there. Textbox meant for accepting search string.
In footer.ascx one textbox and one button is there. Textbox meant for accepting Email-Id.
Now in validation of header.ascx I had done blank checking by JavaScript. And in validation of footer.ascx I had done blank-checking and e-mail checking by javascript.
In both the control the textbox and the button both resides under Panel control whose
DefaultButton property set to the respective button ids. So that if User write write something and press ENTER key from keyboard then it should do whatever respective Button_Clicks will do.
Now My problem is suppose I place the mouse cursor in footer.ascx's textbox and press the ENTER key it validates properly but after that if I place the cursor inheader.ascx's textbox and press the ENTER then it is not working. Again If I do the opposite then also first one will fire but in case of second it is not firing .......

I am facing an interesting issue related to user control validation. I have a strongly typed user control with address entity. I have also created the address entity metadata class with validation definitions. This user control is basically to search and get the address based on the pincode user input. Pincode field is part of the user control and I have defined the required field and regexp validator for pincode field in the address metatdata class.
Now the user control is partially rendered in the customer page where I want to validate the pincode field in the customer page when the user clicks the search button in the user control.But the strange thing is the validation is not working as expected when I click the search button but when I bind the form collection to the entity using update module, I am getting an error. Can anyone help me what all I need to consider in the control ascx page and in the customer aspx page and in the controller?

I have a text box that is intended for an Email address. I am using a Regular eExppression validation control to validate the email address. When I place the following lines of code in a blank web Form, the validator works properly.
<asp:TextBox ID="Email" runat="server" CssClass="DefaultTextBox TextboxWidth" MaxLength="80"></asp:TextBox>
<asp:RegularExpressionValidator ID="valEmail" runat="server" ControlToValidate="Email" ErrorMessage="Invalid Email address" SetFocusOnError="True" ToolTip="Invalid Email address" ValidationExpression="w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*">*</asp:RegularExpressionValidator`>
However, when I use the validation control within a CreateUserWizard control, it does not seem to fire but other validation controls (Required and Custom validators) do fire, but not the regular expression validator above for validating the address. The following is my complete web page. The two controls above appear unchanged in the code below, they are simply embedded into the wizard control mentioned.
<%@ Page Title="" Language="VB" MasterPageFile="~/Master Pages/MasterPage.master" AutoEventWireup="false" CodeFile="Login.aspx.vb" Inherits="Login" %>
<%@ MasterType VirtualPath="~/Master Pages/MasterPage.master" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">

{

}
.Heading
{
font-weight: bold;
font-size: 12pt;
color: rgb(44, 68, 105);
}
.StdFrameWidth...............

i have a form which asks for date of birth. find below the code.
<asp:DropDownList ID="ddlDay" runat="server">
</asp:DropDownList>
<asp:DropDownList ID="ddlMonth" runat="server">
[Code]....
The dropdownlist is populated in code behind. The client and server validation code is,
function valDate_ClientValidate(source, args) {
var dd_id = document.getElementById("<%=ddlDay.ClientID %>");
var mm_id = document.getElementById("<%=ddlMonth.ClientID %>");
[Code]....
When i open this page and select the dropdown DD, an asterisk appears showing the error message. But i dont need this one,as the error should appear only when the form is submitted.

I have a dropdown list control which I populate at run time with the first item being like "-- Select an Item --", for example. I need the user to select an item from the list apart from the first item displayed. I tried using required field validators and setting the InitialValue property to "-- Select an Item --". But this does not seem to work. dropdown list is programmtically populated based on certain decisions presented to the user.
