The update doesn't work successfully. I mean it does not reflect in database. It just according to code, redirects to the specified page. Please help me where i am going wrong.

Actually the problem is now solved. I thank all of you for your concerns.
The problem was solved by just putting if not postback condition.
if (!Page.IsPostBack)
{
if (Request.QueryString["P_Id"] != null)
{
....
}
}

asp:LinkButton - validate form field

I am completely new to C# and I am trying to figure out form validation.
More specifically, I have a webform (C#) that I've split into to parts "form-part-1" and "form-part-2".
By default "form-part-2" is hidden. Once all fields in "form-part-1" are completed, you should be able to proceed to "form-part-2" by clicking on the "Continue" linkButton.
The jQuery part works well, showing and hiding form sections as desired.
But the validation is not enforced anymore.
I have validators in place but at this point I can proceed to "form-part-2" without filling out the "form-part-1" fields.
I would like the validation to be enforced before proceeding to "form-part-2".
Any tips and suggestions how to do it would be greatly appreciated.
Thanks in advance.
Here's my code:
<script language="javascript" type="text/javascript">
$(document).ready(function () {
$("#continue").click(function (event) {
$('#form-part-1').hide();
$('#form-part-2').fadeIn();
});
});
</script>

**** EDIT:
Thanks Phx & Daniel for your feedback. Very helpful!
I got things working with one exception. The "form-part-2" fields get validated before I even get to the step 2. Any tips how to validate the username / password fields only after I get to the "form-part-2"? Thanks in advance!

As you wrote: I would like the validation to be enforced before proceeding to "form-part-2".
You need to create validations groups in order to validate first N fields and the another N Fields.
So create Validation groups for your controls:
http://msdn.microsoft.com/en-us/library/vstudio/ms227424(v=vs.100).aspx
<asp:textbox id="AgeTextBox"
runat="Server">
</asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator2"
controltovalidate="AgeTextBox"
validationgroup="PersonalInfoGroup"
errormessage="Enter your age."
runat="Server">
</asp:requiredfieldvalidator>
<!--When Button1 is clicked, only validation
controls that are a part of PersonalInfoGroup
are validated.-->
<asp:button id="Button1"
text="Validate"
causesvalidation="true"
validationgroup="PersonalInfoGroup"
runat="Server" />
<asp:textbox id="CityTextBox"
runat="Server">
</asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator3"
controltovalidate="CityTextBox"
validationgroup="LocationInfoGroup"
errormessage="Enter a city name."
runat="Server">
</asp:requiredfieldvalidator>
<!--When Button2 is clicked, only validation
controls that are a part of LocationInfoGroup
are validated.-->
<asp:button id="Button2"
text="Validate"
causesvalidation="true"
validationgroup="LocationInfoGroup"
runat="Server" />
Then use a Diferent validation summary for each group.
Perhaps you need a button for each validation but you can do the trick and use the same button for multiple validation groups:
http://www.aspsnippets.com/Articles/Validate-Multiple-Validation-Groups-with-one-Button-in-ASPNet.aspx
Another example here
http://www.codeproject.com/Tips/401611/Validate-multiple-Validation-group-both-client-and

Phx gives a partial answer. Use his suggestion to create ValidationGroups. Put all your validators in part 1 and part 2 in separate groups.
JQuery does not automatically trigger validation.
You need to call the validation manually with your JavaScript. This can be done by calling Page_ClientValidate which will validate all validators for the passed ValidationGroup.
For example:
$("#continue").click(function (event) {
if (Page_ClientValidate("group1")) {
$('#form-part-1').hide();
$('#form-part-2').fadeIn();
}
});

Retaining textbox text after postback event

I have 3 textBoxes in a page .One of the textBox takes the new Password from the user and according to the password entered by the user , a Label displays Password strength message.But after the message displayed by the Label , the textBox text is cleared.is there a way to retain the text? I have enabled the autopostback for the textbox since i need to use the Comparevalidator for it.
Here is the code snippet-
protected void NewPassEntered(object sender, EventArgs e)
{
if (txtPassword.Text.Length < 4)
{
lblPassStr.Visible = Visible;
lblPassStr.BackColor = System.Drawing.Color.OrangeRed;
lblPassStr.Text = "Password should have more than four characters";
txtPassword.Text = "";
}
else if ((txtPassword.Text.Length > 4) && (txtPassword.Text.Length < 6) && (txtPassword.Text.Contains("#")))
{
lblPassStr.Visible = Visible;
lblPassStr.BackColor = System.Drawing.Color.Green;
lblPassStr.Text = "Password Strength:Medium";
}
else if ((txtPassword.Text.Length > 4) && (txtPassword.Text.Length < 6))
{
lblPassStr.Visible = Visible;
lblPassStr.BackColor = System.Drawing.Color.Yellow;
lblPassStr.Text = "Password Strength:Weak";
}
else if ((txtPassword.Text.Length > 6) && (txtPassword.Text.Contains("#")))
{
lblPassStr.Visible = Visible;
lblPassStr.BackColor = System.Drawing.Color.Blue;
lblPassStr.Text = "Password Strength:Strong";
}
}
}
Is there a way to check multiple special characters efficiently?
The aspx code looks like this-:
<div style="width:400px; height:250px;border-color:GoldenRod ;border-style:solid;border-width:thin;padding:20px 50px 50px 20px; position:relative; margin:100px 100px; margin-left:344px">

</td>
</tr>
</table>
</div>
<asp:ValidationSummary ID="ValidationSummary1" Font-Italic="true" font-size="Small" forecolor="Black" runat="server" />

Don't postback the whole page for just setting a Password strength label. Use Javascript for this. There will be 2 benefits of using javascript here.
1) The page will not be postback (By Postback whole page will be refreshed and just because of a single field whole page postback is not a good practice)
2) No need to maintain the state of textbox as there is no postback.

What about using EnableViewState =false ?
<asp:TextBox ID="txtoldpass" runat="server" EnableViewState ="False" CssClass="text" TextMode="Password"
Width="300px" Height="25" ></asp:TextBox>

What is the error in my Validation in asp.net application?

net application. With this application a user can add a guestconnection for a time. for this i have a button that open a modal dialog who a user can add a guest. the input must be a firstname,lastname,company and the time. i use the validation controls and a ValidationGroup. The Validationcontrols check if I forget a input but if I click on "add" the code doesn't run. I try this with a simple div but the same method:
Here is my aspx code:
<div id="add">
<div id="Div2" class="popupConfirmation" runat="server" style="width:350px; height:290px;">
<div class="bodycontrol">

<br />
<table>
<tr>
<td><asp:Label ID="Label10" runat="server" Text="*Bitte alle Felder ausfüllen"></asp:Label></td>
</tr>
</table>
</div>
</div>
</div>
here is my c# code:
protected void btn_GuestListViewAddDialog_YES_Click(object sender, EventArgs e)
{
if (Page.IsValid) //Here i make a breakpoit but it doesn't use this code :(
{
...//here is my code
}
}
this is in my script block if i click on the linkbutton:
WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$lw_content$LinkButton1", "", true, "valid", "", false, true))

If you want to force validation on serverside you need to call Page.Validate() before you check Page.IsValid.
protected void btn_GuestListViewAddDialog_YES_Click(object sender, EventArgs e)
{
Page.Validate();
if (Page.IsValid)
{
The LinkButton must also have a ValidationGroup, the same valid-group if you want to validate this group if the link-button was clicked or a different group if you don't want to trigger validation.
Edit: However, Page.Validate should be redundant since CausesValidation is true by default for a LinkButton and you have specified also a ValidationGroup for it. So i'm at a loss.

Controls does not exist in current context in ASP.Net CreateUserWizard

I am working on a project in Microsoft Visual Studio using an ASP.NET web application with code behind in C#. I added a CreateUserWizard and customized the form in step 1. From the events handler I put a CreatedUser handler into the codebehind to update database tables.
I want to pull the data values for the handler from the form, but the codebehind file can't see them for some reason. Help!

I get these errors at compile time:
Error 1 The name 'FName' does not exist in the current context C:\MV_Training\Jan2013\C#Projects\AcmePresentation\AcmePresentation\Register.aspx.cs 20 41 AcmePresentation

Error 3 The name 'RoleSelector' does not exist in the current context C:\MV_Training\Jan2013\C#Projects\AcmePresentation\AcmePresentation\Register.aspx.cs 20 65 AcmePresentation
and this from the browser:

Thanks,

You want to cast controls explicitly something like this -
public void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
var fNameTextBox = (TextBox)CreateUserWizardStep1
.ContentTemplateContainer.FindControl("FName");
var lNameTextBox = (TextBox)CreateUserWizardStep1
.ContentTemplateContainer.FindControl("LName");
var usernameTextBox = (TextBox)CreateUserWizardStep1
.ContentTemplateContainer.FindControl("UserName");
MembershipUser user = Membership.GetUser(usernameTextBox.Text);
Guid userId = (Guid)user.ProviderUserKey;
}
