Hi Martin,
I have created a custom field in:
Development > System Tables > User Table
Now I am using the webpart called "Users Viewer" on my page with a transfomation called
community.transformations.rr-userslist (Code below). In this transformation I want to get the custom field value, that I created in "User Table"
<cms:usermenucontainer runat="server" ID="userMenuElem" MenuID="userContextMenu" Parameter='<%# Eval("UserID").ToString() %>' ContextMenuCssClass="UserContextMenu" >
<tr>
<td>
<a href="<%# HTMLEncode(GetMemberProfileUrl(Eval("UserName"))) %>" title="<%# Eval("UserName") %>">
Edit
</a>
</td>
<td>
<%# Eval("FirstName") %>
</td>
<td>
<%# Eval("UserName") %>
</td>
<td>
<%# GetDateTime("UserCreated","dd-MMM-yyyy") %>
</td>
</tr>
</cms:usermenucontainer>
