Web Forms :: Buttons Not Working Having RequiredFieldValidator / RegularExpressionValidator Working
Feb 5, 2010
i do have a form. inside specific asp:textboxes are "secured" by RequiredFieldValidator and RegularExpressionValidator running. in another div-element i do have buttons, which are expected to load different pages of my website. the problem is: when i click on either of these buttons it is not working as my validation-controls are fired prior to the onclick-button-events.

My implementation is simple. I have a public static variable in a class called EmailHelper containing my regular expression as follows:
[Code]....
I then have the following web controls on my page:

The problem is that doesn't matter what regular expression I define as the value of my static public variable bound to the <asp:RegularExpressionValidator />, I always get an error (i.e. it aways says "invalid email")...

I create a new website in VS 2010 (VB .Net). I add a table, within it i add a textbox, a button and a RequiedFieldValidator. I set the RFV ControlTValidate property to the textbox. When i move(click or tab) away from the textbox, the RFV doesnt kick in the error message that i have set.
The RFV code is
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="txtEnterName" ErrorMessage="RequiredFieldValidator"
InitialValue="0" ForeColor="#FF3300"></asp:RequiredFieldValidator>
Texbox
<asp:TextBox ID="txtEnterName" runat="server" Width="221px"></asp:TextBox>

The above control is firing the error message -- even when a valid email address is entered. Any idea what I am doing wrong?

I have a 'City' TextBox on one of my web pages but people from many European countries sometimes prefix the city name with the postcode instead of putting it in my dedicated 'Postcode/ZIP' TextBox. I have therefore just added a new RegularExpressionValidator to this TextBox. Its purpose is to prevent the user from entering any numeric characters but allow everything else. After browsing for a suitable regex (I am not a regex expert), I found the following code that was claimed to do what I want.
ValidationExpression="^D$"
Unfortunately, the RegularExpressionValidator does not work as expected. Instead of just rejecting numeric characters it appears to reject everything! Where might I be going wrong?

I have the following code:
<asp:RadioButtonList
ID="rbltest"
RepeatDirection="Horizontal"
RepeatLayout="Flow"
[Code]....
If the user submits this form, and they have not selected a option , I'd expect the validator to catch it but it's not.
How can I get my validator to ensure that one of the option radio buttons are selected?

I've recently finished building one of my first websites (and CMS) in ASP.NET but have came across a problem where a RequiredFieldValidator isn't working as it should do? I originally created the admin page to not require the RequiredFieldValidator, but now that I do need it the page won't acknowledge it's there. I have even set the field in the database to not accept nulls, but the query will still insert a null value into the database (SQL Server 2008 Express).
The TextBox that I'm referring to is "txtSectionTitle"

Does the RegularExpressionValidator always need a RequiredFieldValidator?I see that when there is no input the RegularExpressionValidator is not working. Correct?

I have a FormView in which I have placed RequiredFieldValidators on some of the input controls in EditItemTemplate. But the validators all don't work when I hit the submit button.
I've tried FormView1.FindControl("RequiredFieldValidator1").Enabled = true but the compiler complains that 'System.Web.UI.Control' does not contain a definition for 'Enabled'.
See my code below:

I have a dropdown list, where when I select OPTION value a Textbox appears. The issue is that when, I submit directly the required filed errors gives me message for both ie for dropdown and Textbox. It should only give error for dropdown.
Second thing,
The textbox validation is not firing when submitted without any value in it.
see the code for your reference:
<asp:DropDownList ID="ddlGraduation" runat="server" CssClass="txtfld-popup_drp1">
</asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqGraduation" runat="server" ControlToValidate="ddlGraduation" ErrorMessage="Please select

I use 2 requiredfiledvalidator for 2 selects, one is working but the second one (the one I need) isnt
<asp:dropdownlist id="ddlMod" runat="server" Width="235px" AutoPostBack="True" Font-Names="Arial" Font-Size="XX-Small">
</asp:dropdownlist>
<asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server" Font-Names="Arial" Font-Size="XX-Small"
ErrorMessage="Select Mod" InitialValue="00" Display="Dynamic" ControlToValidate="ddlMod">
</asp:requiredfieldvalidator>
<asp:dropdownlist id="ddlInd" runat="server" Width="235px" AutoPostBack="True" Font-Size="XX-Small">
</asp:dropdownlist>
<asp:requiredfieldvalidator id="RequiredFieldValidator2" runat="server" Font-Names="Arial" Font-Size="XX-Small"
ErrorMessage="Select Ind" InitialValue="0" Display="Dynamic" ControlToValidate="ddlInd">
</asp:requiredfieldvalidator>
If i select the 2nd one I can see the error message for the 1st one, but I can't see any message if I dont select any or if I select the 1st one.

As the title says. What could be amiss?
I have a regular TextBox on my page - <asp:TextBox ID="tb" runat="server" />
The following works:
<asp:RequiredFieldValidator ID="r" runat="server" ControlToValidate="tb" ErrorMessage="error" />
The following does not work:
RequiredFieldValidator rfv = new RequiredFieldValidator();
rfv.ID = "rfv";
rfv.ControlToValidate = tb.ID;
rfv.ErrorMessage = "error";

I have a WebForms app that uses a field validator on a dropdownlist. It works in IE but not FireFox. This is pretty straightforward stuff I'm doing. Here are the setups for the dropdown and validator:
<asp:DropDownList ID ="dmbFileActNo" runat="server" CssClass="DROPDOWN_MEDIUM" AutoPostBack="True"></asp:DropDownList>
<asp:requiredfieldvalidator EnableClientScript="true" id="rfvFileActNo" Display="None" ControlToValidate="dmbFileActNo" Runat="server" InitialValue="-1"></asp:requiredfieldvalidator>
I'm running ASP.Net 2.0 on the web server. Javascript is enabled on the FireFox browser-- this problem happens on all FF browsers I've tested, on multiple everyday machines, so I don't believe it's due to a locked down install.

m new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button,
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

I have problem with the buttons Edit and Delete in Gridview for very long time and i really need about it. So the when i click edit i get in edit mode and when click update the values in the row i was changing disappear but only in the gridview. When check in the Database nothing happens. The delete button not works at all, i mean when click on it only refresh the table.

I've implemented group and grand totals on a gridview as per [URL].
My problem is that the last few link buttons does not function correctly (in this case ID 11 and 12) when I click on them. I am thinking that it could be because of the manual rows being added and then throwing out the links for the other rows, but I honestly don't know what is causing it.
So if you look at my example clicking on the link buttons for IDs 1 through 10 they all redirect correctly as for example detailsPage.aspx?q=4 when I click on ID 4, but when I click on link button 11 or 12 it just reloads the page removes with totals removed and some blank rows in between.
