Customize the Registration form

Hello,

My goal: Have the UserName field always default to the registered user's email address and then to hide the UserName row whenever DNN builds a related form control. I do this to accomodate the SSO solution I devised of which currently uses the email address as the login. I was able to accomplish the UserName modification but only by doing a rough hack of the DNN PropertyEditorControl.vb and the UserInfo.vb.

I would prefer to be able to access the UserName textbox and lable via the ManageUsers.ascx (of which I cloned within my own PA for the SSO fix). Is there anything anyone can suggest regarding this? I was thinking somehow of getting a reference to the User.ascx's UserEditor object and then effect the visibility property kind of how I hacked it the PropertyEditorControl.vb? I don't know, I am open to any suggestion. Anyway, what is up with this UserName field anyway. I know the Microsoft provider needs it, but there should be a clearer way to work with these "required" fields...in my opinion.

Anyway, Thanks!

<td class="SubHead" width="175">
  <dnn:label id="plUserName" runat="server" controlname="txtUsername" text="User Name:"></dnn:label></td>
<td class="NormalBold" noWrap>
  <asp:textbox id="txtUsername" tabIndex="3" runat="server" cssclass="NormalTextBox" size="25"
   maxlength="175"></asp:textbox>
  <asp:label id="lblUsernameAsterisk" runat="server">*</asp:label>
  <asp:label id="lblUsername" runat="server"></asp:label>
  <asp:requiredfieldvalidator id="valUsername" runat="server" cssclass="NormalRed" display="Dynamic" errormessage="<br>Username Is Required."
   controltovalidate="txtUsername" resourcekey="valUsername"></asp:requiredfieldvalidator></td>

Then go to the vb page and look for this.

Public Property UserName() As String
Get
UserName = txtUsername.Text
End Get
Set(ByVal Value As String)
_UserName = Value
End Set
End Property

Then just change the line UserName=txtUsername.Text to be UserName=txtEmail.Text

ANY TIME I make a small change like this in the system. I usually use some kind of unique rem statement so that I can easily do a search for things I've changed or removed. So like on the vb page mine would look like this with an extra .,. so I can find it.REM.,. UserName = txtUsername.Text
UserName = txtUsername.Text

At one time I was thinking of doing something very similar. I wanted to just have my users use their email for login. The problem is, once you start changing this type of thing you have to do all of it. So to do this in DNN I was going to do this with this methodology. First, find an existing set of registration pages that you like. So for me, I like the UCanUse User Attribute Module. This one lets me do a lot of extending of the registration like adding new items. You can also do this with the DNN registration page though. Create a new project out of it. Copy the register and user.ascx and vb pages to it and do the changes. If you're looking for a quick and simple short cut you could just edit the exiting registration module page. The control that handles the user login is user.ascx under the directory \dotnetnuke\controls\. Go in there and change the user.ascx page. First what you do is just rem out the whole username row. Either rem out or delete this area of the ascx

Re: Customize the Registration form

Now I'm really confused...

The registration form I want to change (DNN ver 3.3.6) is 'admin\users\ManageUsers.ascx' of which the user control that contains the 'UserName' object is 'admin\users\User.ascx'. It appears to me that this User.ascx holds a reference within a placeholder to 'controls\propertyeditor\PropertyEditorControl.vb' (referenced as 'UserEditor'). It seems the User.ascx.vb's 'Sub DataBind' routine is called to build the User.ascx UserName object (along with the other required registration objects e.g. Email). It appears the DataBind essentially causes the PropertyEditorControl to take the 'components\users\UserInfo.vb' class (in this case) and build the necessary objects (textboxes, labels, etc..). The PropertyEditorControl is reading attributes that decorate the class properties to determine how to handle building the UserName, ect. objects on the User.ascx control (in this case).

With that said, are you suggesting that I bypass this User.ascx and replace the reference in the ManageUsers.ascx with the 'controls\User.ascx' and then follow your instructions? If I do that it would seem I would then not have the dynamic registration field capability that the PropertyEditorControl now gives me??

And while I'm asking, possibly you or someone could tell me where/how DNN is updating the UserInfo class after the user selects register and the form postback occurs. I can not figure out how the text typed into the various textboxes i.e. UserName get hydrated into the associated UserInfo class...how is this happening, I can't find any sort of UpdateUser code that gets called in any of the User.ascx or parent classes. I see how the DataBind is called initially to build the textbox objects but where in the postback process are the textbox text values hydrated back into the UserInfo class??? A real mystery to me!

Any help on this would be very much appreciated!!
