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!

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;
}

I am trying to clear the form on cancel button click with a function clearForm() that uses String.Empty with each field of the form but this is not working. I am neither getting any error nor getting the expected result.

Here's my code-behind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Globalization;
public partial class AddEmployee : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn_ClearForm(object sender, EventArgs e) //to clear form on IsPostBack or on press of cancel button
{
if (!IsPostBack)
{
clearForm();
}
}
#region public functions
public void clearForm()
{
txtName.Text = String.Empty;
txtAddress.Text = String.Empty;
txtDoB.Text = String.Empty;
txtDesig.Text = String.Empty;
txtSal.Text = String.Empty;
txtEmail.Text = String.Empty;
txtUser.Text = String.Empty;
txtPass.Text = String.Empty;
txtConfPass.Text = String.Empty;
GenderList.Items[0].Selected = true;
GenderList.Items[1].Selected = false;
}
#endregion
}
There is nothing wrong with string.Empty. But you do not need condition in btn_ClearForm as btn_ClearForm handler will always called on postback and you put the condition if !IsPostBack
// if (!IsPostBack)
//{
clearForm();
// }
Your code would be
protected void btn_ClearForm(object sender, EventArgs e)
{
clearForm();
}
Got the fix!
Just use CausesValidation="false" on the cancel button so as to disable validation upon cancel button click event.
Because when you have used validation on your controls without using CausesValidation="false" on the cancel button, your controls will be forced to pass through validation conditions given to them and since the cancel button is meant to clear your form regardless of checking the validity of the data in form fields, the form will get stuck.
So whenever you have used validation conditions on your controls, just make sure you don't get them fired on the click of Cancel/clear/reset button.
Thanks

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)
{
....
}
}
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!
here's my most recent version:
www.smithy.somee.com
and the code:
<script language="javascript" type="text/javascript">
$(document).ready(function () {
if (Page_ClientValidate("personalGroup")) {
$('#form-part-1').hide();
$('#form-part-2').fadeIn();
}
if (Page_ClientValidate("accountGroup")) {
$('#form-part-2').hide();
}
});
</script>
<form id="signup" runat="server">
<div>
<table id="validators">

<td>
<asp:ValidationSummary ID="personalGroupSummary" runat="server" ValidationGroup="personalGroup" />
<asp:ValidationSummary ID="accountGroupSummary" runat="server" ValidationGroup="accountGroup" />
</td>
</tr>
</table>
<table id="form-part-1">
<tr>
<td>First Name:</td>
<td><asp:TextBox ID="txtFname" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td>Last Name:</td>
<td><asp:TextBox ID="txtLname" runat="server"></asp:TextBox></td>
</tr>
<tr>

<td>
<asp:Button ID="continue" runat="server" causesvalidation="true" validationgroup="personalGroup" Text="Continue" />

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();
}
});
I have added DropDownList1 in Default.aspx page my ASP.Net project, and I have the below code in Default.cs:
if(DropDownList1.SelectedItem.ToString()=="")
I got this error:
Error 2 The name 'DropDownList1' does not exist in the current context
Edit:
In *.cs:
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
string username = Login1.UserName;
string pwd = Login1.Password;
var connstring = ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString; ;
var conn = new SqlConnection(connstring);
conn.Open();
SqlCommand command;
if(DropDownList1.SelectedItem.ToString()=="")
command = new SqlCommand("Select [ID] from [Inspector] WHERE [ID] =" + username + " AND [Password] ='" + pwd + "';", conn);
SqlDataReader dr = command.ExecuteReader();
if (dr.Read())
{
if (dr[0].ToString() == username)
{
Session["UserAuthentication"] = username;
Session.Timeout = 1;
Response.Redirect("MainInspector.aspx");
}
else
{
Session["UserAuthentication"] = "";
}
}
}

You need to check your markup to confirm that the ID matches i.e.
<asp:DropDownList id="DropDownList1".....
If it is a web application the designer.cs file could be messed up as this has the reference within it.
Something like this:
protected global::System.Web.UI.WebControls.DropDownList DropDownList1;
If it is missing try adding the above.
Such errors might appear when the markup in the .aspx page (or .ascx control) is not well formed. In cases where the markup is bad, when you add a new control its declaration is not added in the designer file and leads to this error.
If this is the case, one common trick to fix this is to cut and paste the markup of the control. This way you re-add the control and make Visual Studio to re-add the declaration of the control in the designer file.
DropDownList1 does not exist in the current context
The solution for me was to place the DropDownList outside of of the LoginView.
Try moving the DropDownList to another section of your page and see if this works.
I am adding some regex with the register user steps, they are working because the '*' is being displayed but the Wizard will still let me create an account with errors of regex.
I tried to redo the wizard
Changing some features but nothing

Assuming your Create Use wizard looks like this
<asp:CreateUserWizard ID="CreateUserWizard1" runat="server" OnCreatedUser="CreateUserWizard1_CreatedUser"
DisableCreatedUser="true" EmailRegularExpression="^((?:(?:(?:\w[\.\-\+]?)*)\w)+)\#((?:(?:(?:\w[\.\-\+]?){0,62})\w)+)\.(\w{2,4})$"

<ValidatorTextStyle Font-Size="Small" />
<WizardSteps>
<asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
</asp:CreateUserWizardStep>
<asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server">
</asp:CompleteWizardStep>
</WizardSteps>
</asp:CreateUserWizard>
You can access the validators as follows:
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("UserNameRequired")
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("PasswordRequired")
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("ConfirmPasswordRequired")
(RequiredFieldValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("EmailRequired")
(CompareValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("PasswordCompare")
(RegularExpressionValidator)((CreateUserWizardStep)CreateUserWizard1.FindControl("CreateUserWizardStep1")).ContentTemplateContainer.FindControl("EmailRegExp")
Hope this helps
Thank You :)
Use the correct ID for ValidationGroup.
Should be "RegisterUser" instead of "CreateUserWizard1"
