CreatePage.aspx

I had a require the other day from a user, they wanted to remove certain page layouts from the CreatePage depending on a certain user.

We found that this couldn't be achieved with user permissions so instead I copied the CreatePage.aspx, inherited the class, and manually filtered the avaiable page layout.

If logic behind it goes, if the user belongs to a certain group then hide certain layouts from them.

The usergroup and layouts to hide come from the Web.config.

using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI.WebControls;
using Microsoft.SharePoint;

namespace Leelodharry.Sharepoint
{
public class CreateIntranetPage : Microsoft.SharePoint.Publishing.Internal.CodeBehind.CreatePagePage
{

protected override void OnLoad(EventArgs e)
{
Microsoft.SharePoint.Publishing.Internal.WebControls.DropDownListWithDetails dd = this.pageTemplatePicker;


base.OnLoad(e);

if (!IsPostBack)
{
Microsoft.SharePoint.Publishing.Internal.WebControls.DropDownListWithDetails.ItemInfo[] ItemInfoArray = dd.DataList;

string id = dd.DropDownListId;
DropDownList drop = (DropDownList)dd.Controls[0].Controls[1];


System.Collections.IDictionary stsh = (System.Collections.IDictionary)System.Configuration.ConfigurationSettings.GetConfig("PageLayoutRestriction");
string FindGroup = (string)stsh["UserGroup"];


SPUser user = SPContext.Current.Web.CurrentUser;

bool IsAMember = UserIsMemberOf(user, FindGroup);

if (!IsAMember)
{
string LayoutAttributeValue = (string)stsh["CanSeeLayouts"];
string[] RestrictedLayouts = LayoutAttributeValue.Split(',');

for (int idx = 0; idx < RestrictedLayouts.Length; idx++)
{
string RemoveLayout = RestrictedLayouts[idx].Trim();

FindAndRemove(drop, RemoveLayout);
}

}



}
