How do I go about accessing the text input from a textbox within a content template in my C# code behind file?

Question

I have used a few variations of accessing the text from StreetNbrtxt including

1) Directly: Profile.StreetNbr = StreetNbrtxt.Text; (Didn't work)
2) Using FindControl: Profile.StreetNbr = ((TextBox)RegisterUserWizardStep.FindControl("StreetNbrtxt")).Text; ('Not a instantiated class' Error message)

Further, I have not been able to see the values that I added in the text boxes that were added to the pre-coded files that were in the Account folder in Visual Studio Express 2012.

The code I have from the Register.aspx is as follows:

    <asp:CreateUserWizard runat="server" ID="RegisterUser" ViewStateMode="Disabled" OnCreatedUser="RegisterUser_CreatedUser" ActiveStepIndex="0">
    <LayoutTemplate>
        <asp:PlaceHolder runat="server" ID="wizardStepPlaceholder" />
        <asp:PlaceHolder runat="server" ID="navigationPlaceholder" />
    </LayoutTemplate>
    <WizardSteps>
        <asp:CreateUserWizardStep runat="server" ID="RegisterUserWizardStep">
            <ContentTemplate>
                <p class="message-info">
                    Passwords are required to be a minimum of <%: Membership.MinRequiredPasswordLength %> characters in length.
                </p>

                <p class="validation-summary-errors">
                    <asp:Literal runat="server" ID="ErrorMessage" />
                </p>

                <fieldset>
                    <legend>Registration Form</legend>
                    <ol>
                        <p>
                            <asp:Label runat="server" AssociatedControlID="UserName">User name</asp:Label>
                            <asp:TextBox runat="server" ID="UserName" />
                            <asp:RequiredFieldValidator runat="server" ControlToValidate="UserName"
                                CssClass="field-validation-error" ErrorMessage="The user name field is required." />
                        </p>
            :
            :
            :
            :
            :
                        <p>
                            <asp:Label ID="StreetNumberlbl" runat="server" AssociatedControlID="StreetNbrtxt">Street Number:</asp:Label>
                            <asp:TextBox ID="StreetNbrtxt" runat="server" CssClass="style11"></asp:TextBox>
                            <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="StreetNbrtxt"
                                CssClass="failureNotification" ErrorMessage="A street address number is required" ToolTip="Please insert your home address number"
                                ValidationGroup="RegisterUserValidationGroup">*</asp:RequiredFieldValidator>
                        </p>    
                    </ol>               
        <asp:Button runat="server" CommandName="MoveNext" Text="Register" />
         </fieldset>
            </ContentTemplate>

Any Idea of how I should access the Street Number from the user input textbox?

Answer 1

CreateUserWizard Control is based on Wizard control, which has steps. So you need to find the control inside the step. In your case, it is in the first step. You can access the control like this.

TextBox StreetNbrtxt = 
(TextBox)RegisterUser.WizardSteps[0].
FindControl("CreateUserStepContainer").FindControl("StreetNbrtxt");

You can see how it works. I hope this works for you too, as it is working for me for a long time. Thanks!
