This pattern is used for adding or removing user from the Site Groups.
As mentioned earlier, on form load, all the site groups corresponding to the site collection will be shown. The checked checkboxes would determine, the user is already present in the particular Site Group and vice versa.
If one wants to add a user to a particular Site Group, the corresponding checkbox should be checked. Similarly, if one wants to remove the user from the Site Group, corresponding checkbox should be unchecked.
On the click of the Save button, the user would be added to all the Site Groups that are checked and removed from the others.
The code for adding user to site group is defined in the AddUserToSelectedSiteGroups method:
XPathNavigator root = MainDataSource.CreateNavigator();
List<string> selectedGroups = new List<string>();
XPathNodeIterator iter = root.Select("//my:myFields/my:SiteGroups/my:SiteGroup", NamespaceManager);
string prevGroups = root.SelectSingleNode("/my:myFields/my:prevSiteGroups", NamespaceManager).Value;
string[] prevSitegroups = new string[] { };
string[] currSitegroups = new string[] { };
if (prevGroups.Length > 0)
{
prevSitegroups = prevGroups.Split(','); // get all previously selected site groups
}
while (iter.MoveNext())
{
string value = iter.Current.Value;
if (value != null && value != "")
{
XPathNavigator siteGroups = DataSources["SiteGroupsRestService"].CreateNavigator();
XPathNavigator nav = siteGroups.SelectSingleNode("/ns1:feed/ns1:entry/ns1:content/m:properties/ns2:Title[../ns2:Id = '" + value + "']", NamespaceManager);
if (!selectedGroups.Contains(nav.Value))
{
selectedGroups.Add(nav.Value);
}
}
if (selectedGroups.Count > 0)
{
if (prevSitegroups.Length > 0)
{
currSitegroups = selectedGroups.ToArray();
IEnumerable<string> deleteUserFromGroups = prevSitegroups.Except(currSitegroups);
IEnumerable<string> addUserToGroups = currSitegroups.Except(prevSitegroups);
AddOrRemoveUserToGroup(deleteUserFromGroups, UserOpType.RemoveUser);
AddOrRemoveUserToGroup(addUserToGroups, UserOpType.AddUser);
}
else // Add user to site groups if there is no previously selected groups
{
AddOrRemoveUserToGroup(selectedGroups, UserOpType.AddUser);
}
} // if (groups.Count > 0)
else if (prevSitegroups.Length > 0) // if enduser unselect all options, remove user from site group
{
AddOrRemoveUserToGroup(prevSitegroups, UserOpType.RemoveUser);
}
} // private void AddUserToSiteGroups()As a result the checkbox corresponding to Site Group “RajDev Owners” is checked, which means, the user would be added to that Site Group as shown in the below figure:
As mentioned earlier, on form load, all the site groups corresponding to the site collection will be shown. If one wants to add a user to a particular Site Group, the corresponding checkbox should be checked. Similarly, if one wants to remove the user from the Site Group, corresponding checkbox should be unchecked.
On the click of the Save button, the user would be added to all the Site Groups that are checked and removed from the others.
Code for adding or removing a user from site group is in the AddUserToSelectedSiteGroups JavaScript function inside the EmpViewModel JavaScript function:
self.addOrRemoveUserToOrFromSiteGroups = function () {
var addUsers = $(self.UserSiteGroups()).not(self.PreviouslySeletedSiteGroups());
for (var i = 0; i < addUsers.length; i++)
{
self.addUserToSiteGroup(addUsers[i]);
}
var deleteUsers = $(self.PreviouslySeletedSiteGroups()).not(self.UserSiteGroups());
for (var i = 0; i < deleteUsers.length; i++)
{
self.removeUserFromSiteGroup(deleteUsers[i]);
}
return true;
}; As a result the user would be added to the Site Groups corresponding to the checkboxes checked as well as removed from the Site Groups which are unchecked.
In the above example, the checkbox corresponding to Site Group “Excel Services Viewers” is checked, which means, the user would be added to that Site Group as shown in the below figure:
As mentioned earlier, on form load, all the site groups corresponding to the site collection will be shown. If one wants to add a user to a particular Site Group, the corresponding checkbox should be checked. Similarly, if one wants to remove the user from the Site Group, corresponding checkbox should be unchecked.
On the click of the Save button, the user would be added to all the Site Groups that are checked and removed from the others.
The code to adding the user to the selected Site Group is in the EmployeeController inside method AddUserToSelectedSiteGroups:
List<int> selectedGroups = new List<int>();
int[] newGroups = new int[] { };
int[] prevGroups = model.PreviouslySelectedSiteGroups;
foreach (SiteGroup grp in model.SiteGroups)
{
if (grp.Checked)
{
selectedGroups.Add(grp.Id);
}
}
if (selectedGroups.Count > 0)
{
if (prevGroups != null && prevGroups.Length > 0)
{
newGroups = selectedGroups.ToArray();
IEnumerable<int> deleteUserFromGroups = prevGroups.Except(newGroups);
IEnumerable<int> addUserToGroups = newGroups.Except(prevGroups);
AddOrRemoveUserToGroup(deleteUserFromGroups, UserOpType.RemoveUser, clientContext, userID);
AddOrRemoveUserToGroup(addUserToGroups, UserOpType.AddUser, clientContext, userID);
}
else // Add user to site groups if there is no previously selected groups
{
AddOrRemoveUserToGroup(selectedGroups, UserOpType.AddUser, clientContext, userID);
}
} // if (groups.Count > 0)
else if (prevGroups != null && prevGroups.Length > 0) // if enduser unselect all options, remove user from site group
{
AddOrRemoveUserToGroup(prevGroups, UserOpType.RemoveUser, clientContext, userID);
}
else if (prevGroups != null && prevGroups.Length > 0) // if enduser unselect all options, remove user from site group
{
AddOrRemoveUserToGroup(prevGroups, UserOpType.RemoveUser, clientContext);
}As a result the user would be added to the Site Groups corresponding to the checkboxes checked as well as removed from the Site Groups which are unchecked.
In the above example, the checkbox corresponding to Site Group “Excel Services Viewers” is checked, which means, the user would be added to that Site Group as shown in the below figure:

In Default.aspx.cs there the method AddUserToSelectedSiteGroups that implements the logic to add user to selected Site Group:
List<string> selectedGroups = new List<string>();
string[] newGroups = new string[] { };
string[] prevGroups = hdnPreviouslySelectedSiteGroups.Value.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
foreach (System.Web.UI.WebControls.ListItem grp in cblSiteGroups.Items)
{
if (grp.Selected)
{
selectedGroups.Add(grp.Value);
}
}
if (selectedGroups.Count > 0)
{
if (prevGroups != null && prevGroups.Length > 0)
{
newGroups = selectedGroups.ToArray();
IEnumerable<string> deleteUserFromGroups = prevGroups.Except(newGroups);
IEnumerable<string> addUserToGroups = newGroups.Except(prevGroups);
AddOrRemoveUserToGroup(deleteUserFromGroups, UserOpType.RemoveUser, clientContext);
AddOrRemoveUserToGroup(addUserToGroups, UserOpType.AddUser, clientContext);
}
else // Add user to site groups if there is no previously selected groups
{
AddOrRemoveUserToGroup(selectedGroups, UserOpType.AddUser, clientContext);
}
} // if (groups.Count > 0)
else if (prevGroups != null && prevGroups.Length > 0) // if enduser unselect all options, remove user from site group
{
AddOrRemoveUserToGroup(prevGroups, UserOpType.RemoveUser, clientContext);
}
}As a result the user would be added to the Site Groups corresponding to the checkboxes checked as well as removed from the Site Groups which are unchecked.
In the above example, the checkbox corresponding to Site Group “Excel Services Viewers” is checked, which means, the user would be added to that Site Group as shown in the below figure:
