                                <asp:Literal ID="ErrorMessage" runat="server" EnableViewState="False"></asp:Literal>
                    <table border="0" cellspacing="5" style="width:100%;height:100%;">
                        <tr align="right">
                            <td align="left" colspan="0">
                                <asp:Button ID="StepNextButton" CssClass="buttonStyle" runat="server" CommandName="MoveNext" 
                                    Text="Create User" ValidationGroup="CreateUserWizard1" />


protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
        TextBox Category = DropDownList1.SelectedValue;

        // Get the UserId of the just-added user
        MembershipUser newUser = Membership.GetUser(CreateUserWizard1.UserName);
        Guid newUserId = (Guid)newUser.ProviderUserKey;

        // Insert a new record into UserProfiles
        string connectionString =
        string insertSql = "INSERT INTO UserDetails(UserId, FirstName, MiddleName, LastName, HomeTown, Category) VALUES(@UserId, @FirstName, @MiddleNAme, @LastName, @HomeTown, @Category)";

        using (SqlConnection myConnection = new SqlConnection(connectionString))
            SqlCommand myCommand = new SqlCommand(insertSql, myConnection);
            myCommand.Parameters.AddWithValue("@UserId", newUserId);
            myCommand.Parameters.AddWithValue("@FirstName", DBNull.Value);
            myCommand.Parameters.AddWithValue("@MiddleName", DBNull.Value);
            myCommand.Parameters.AddWithValue("@LastName", DBNull.Value);
            myCommand.Parameters.AddWithValue("@HomeTown", DBNull.Value);
            myCommand.Parameters.AddWithValue("@Category", Category.Text.Trim());

Error: DropList1 doesn't exist in this context.

ok I seem to have finally found a solution but don't know about its validity.

DropDownList category = (DropDownList)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("DropDownList1");
Please sir look into it and can i use it for further usage.

Hi there,

yes, this is the right approach to find a control in an editable control.
