I have required field validation control for a radiobutton list. So if no values are selected then it gives me a error which is fine. But when i redo select something and click the button then it does't not fires the server event of the button. Once i have the validation erro then whatever i do it disable the server side event.
any ideas why is it happening my code
<div id="studysub_popul" runat="server" visible="false">
<asp:Label ID="lbl_rdb_study_popul" runat="server"
CssClass="questions"
Text="2.Select your study subjects">
</asp:Label>
<asp:RadioButtonList ID="rdb_study_popul" runat="server"
AutoPostBack="True"
OnSelectedIndexChanged="rdb_study_popul_SelectedIndexChanged">
<asp:ListItem>Individuals</asp:ListItem>
<asp:ListItem>Population</asp:ListItem>
</asp:RadioButtonList>
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server"
ControlToValidate="rdb_study_popul"
Display="Dynamic"
ErrorMessage="Study Subject is required"
ValidationGroup="StudySubject">
</asp:RequiredFieldValidator>
</div>
</td>
</tr>
<tr>
<td>
<asp:Button ID="btn_s_section" runat="server"
OnClick="btn_studysubject_section_Click"
Text="Next" ValidationGroup="StudySubject"
Visible="false" />
</td>
You should add a validating group to the RadioButtonList definition too.
<asp:RadioButtonList ID="rdb_study_popul" runat="server"
AutoPostBack="True"
OnSelectedIndexChanged="rdb_study_popul_SelectedIndexChanged"
ValidationGroup="StudySubject">

We have a page that allows users to update data using about a dozen textboxes and several dropdowns. Half of all the fields are permanently visible and the rest are hidden. If a checkbox is checked, the page reveals the rest of the fields.
When first arriving on the page, the two textboxes and dropdown in question are not visible, along with the rest of the fields not visible, unless the checkbox is checked.
However, with the update functionality (a button click) the two textboxes and dropdown appear with the other permanently visible fields. Oddly enough, the labels corresponding to the fields that should be hidden do not appear. Another point is that, if the checkbox is checked and then unchecked, the fields in question are not visible.
So it appears that the issue is with the update functionality but we haven't been able to pinpoint what the issue is. We have tried setting the visibility to false in the .ascx.cs file but that has had zero effect along with other things we've tried.
Is there anything obvious we might be missing from our code below?

I have a asp.net Listview and I have add a RequiredFieldValidator for edit operations in EditItemTemplate.
When I click "Edit" button and try to save the data with an empty CustomerNameTextBox then I get error "Please enter your name!"
This is OK
<%# Page Language="C#" UnobtrusiveValidationMode="None" AutoEventWireup="true" CodeBehind="frmMain.aspx.cs" Inherits="DB_mit_GridView.frmMain" %>
<EditItemTemplate>
<tr style="">
<td>
<asp:Button ID="UpdateButton" runat="server" CommandName="Update" Text="Update" />
<asp:Button ID="CancelButton" runat="server" CommandName="Cancel" Text="Cancel" />
</td>
<td>
<asp:Label ID="CustomerIDLabel1" runat="server" Text='<%# Eval("CustomerID") %>' />
</td>
<td>
<asp:TextBox ID="CustomerNameTextBox" runat="server" Text='<%# Bind("CustomerName") %>' />
<%-- CustomerNameTextBox must not be empty when editing an existing record
<asp:RequiredFieldValidator runat="server" id="reqName" controltovalidate="CustomerNameTextBox" errormessage="Please enter your name!" />
</td>
But I want to check for empty CustomerNameTextBox not only when editing an existing record but also when I insert a new record.
So I add RequiredFieldValidator for Insert operations in InsertItemTemplate :
<InsertItemTemplate>
<tr style="">
<td>
<asp:Button ID="InsertButton" runat="server" CommandName="Insert" Text="Insert" />
<asp:Button ID="CancelButton" runat="server" CommandName="Cancel" Text="Clear" />
</td>
<td>
<asp:TextBox ID="CustomerIDTextBox" runat="server" Text='<%# Bind("CustomerID") %>' />
</td>
<td>
<asp:TextBox ID="CustomerNameTextBox" runat="server" Text='<%# Bind("CustomerName") %>' />
<%-- CustomerNameTextBox must not be empty when insertig a new record
<asp:RequiredFieldValidator runat="server" id="reqName2" controltovalidate="CustomerNameTextBox" errormessage="Please enter your name!" />
</td
But as soon as I add RequiredFieldValidator to InsertItemTemplate I get the message "Please enter your name!" immediately after start of then page.
I have not clicked on the "Insert" button - the message just appears without any click.
So how can I make sure that certain textboxes are not empty when editing or insertig ? (I have no code behind)
You can add validation group for all textboxes and for Insert button

I'm just wondering if there's a way to add a new checkbox item to an existing asp:checkboxlist control, when another checkbox is checked, without having to do a full postback of the page. Whether it's with javascript, jquery, ajax. Just wondering how (if at all) I can do something like this.
I've been doing some research and it appears I can do a partial postback using an asp:UpdatePanel. I've never used one of these before. Does anyone have an example of how they can be used? Here's what I have, but it's still doing a full postback
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<tr>
<td width="50%">
<asp:CheckBox runat="server" ID="chkEnglish" Font-Bold="true" TextAlign="Right" Text=" English" />
</td>
<asp:Panel runat="server" ID="pnlTopLanguages">
<td rowspan="3" valign="top">
<asp:CheckBoxList ID="chkTopLanguages" CssClass="cb chkTopLangs" TextAlign="Right" runat="server" />
<asp:TextBox runat="server" ID="txtOtherLanguages" onkeyup="SetButtonStatus(this)" onclick="return clearLanguageSearchText()" Text="Other Languages..."></asp:TextBox>
<asp:Button runat="server" ID="btnAddLang" Text="Add" OnClientClick="return CopyOtherLangs()" Enabled="false" /><br /><br />
<asp:CheckBox runat="server" ID="chkManyOtherLanguages" CssClass="cb" Font-Bold="true" Text="Many other languages" />
<cc3:AutoCompleteExtender ID="aceSearch" runat="server" MinimumPrefixLength="1" TargetControlID="txtOtherLanguages"
ServicePath="~/controls/wsCommunity.asmx" ServiceMethod="GetLanguageCompletionList"></cc3:AutoCompleteExtender>
</td>
</asp:Panel>
</tr>
</ContentTemplate>
</asp:UpdatePanel>
Building off Adils answer...to add a checkbox on check of another one, you can use:
$(".classOfCheckboxList").change(function() {
$(this).append("<input type='checkbox' id='newbox' class='currentclass' value='someval' />");
});
As Adil said, this new dynamically added box wont be accessible in the code-behind.
This is my first question in stackoverflow.com.
I am working on a school project which I have to validate the input from the user. Everytime the page load, it give the server error message. Please see the codes, and the error message after.
<div>
<table>
<td>
<asp:RadioButton ID="RadioButton1" runat="server"></asp:RadioButton>
<asp:RequiredFieldValidator ID="validateCheck" runat="server" ControlToValidate="RadioButton1" ErrorMessage="Please Enter" Display="Dynamic"></asp:RequiredFieldValidator>
</td>
</table>
</div>
Server Error in '/' Application.
Control 'RadioButton1' referenced by the ControlToValidate property of 'validateCheck' cannot be validated.
The RequiredFieldValidator does not validate a RadioButton. However, you can use the RadioButtonList control instead (validated by RequiredFieldValidator).
The asp:RadioButton do not support validation, instead of RadioButton use a RadioButtonList:'
<form id="form1" runat="server">
<div>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ErrorMessage="RequiredFieldValidator" ControlToValidate="RadioButtonList1"></asp:RequiredFieldValidator>
</div>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
<asp:RadioButtonList ID="RadioButtonList1" runat="server">
<asp:ListItem>One</asp:ListItem>
<asp:ListItem>Two</asp:ListItem>
</asp:RadioButtonList>
</form>
In my asp.net application, I've tried to use validation summary in my web page.I've controls like
<td>First Name *</td>
<td>
<asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox>
<div>
<asp:RequiredFieldValidator ID="reqValStaffFirstName" runat="server"
ErrorMessage="Enter FirstName" Text="*"
ControlToValidate="txtFirstName" Display="Dynamic"
ValidationGroup="valGrpStaffGeneral">
</asp:RequiredFieldValidator>
</div>
</td>
<td>Last Name *</td>
<td>
<asp:TextBox ID="txtLastName" runat="server"></asp:TextBox>
<div>
<asp:RequiredFieldValidator ID="reqValStaffLastName" runat="server"
ErrorMessage="Enter LastName" Text="*"
ControlToValidate="txtLastName" Display="Dynamic"
ValidationGroup="valGrpStaffGeneral">
</asp:RequiredFieldValidator>
</div>
</td>
<td>
<asp:Button Id="btnSave" runat="server" ValidationGroup="valGrpStaffGeneral">
<td>
and my validationsummary script is
<asp:ValidationSummary ID="summary1" ShowSummary="true" runat="server"
ValidationGroup="valGrpStaffGeneral" DisplayMode="BulletList" />
If I click on save button without filling anything in textbox1 and textbox2 its showing validation errors in my validation summary area. If I fill anything in my textboxes and press tab the error(*) disappears automatically, but the error in the validation summary not changing automatically and its displaying until I click on save button, what should I do to make the validation summary change the fixed errors automatically.
This might be of help - look at the EnableClientScript property of the ValidationSummary control.
