found a helper utility for grouping data in a gridview. This is help full since the other way would be nesting gridviews.

Making an ASP.NET page an Rss feed
The following code will give any page the ability to be used as an rss feed automatically
[code lang=”csharp”]
Public class BasePage : System.Web.UI.Page
{
protected override void Render(HtmlTextWriter writer)
{
if (Request.QueryString["rss"] == "true")
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
System.IO.StringWriter sw = new System.IO.StringWriter(sb);
HtmlTextWriter nw = new HtmlTextWriter(sw);
Response.Clear();
writer.Write("");
writer.Write("");
writer.Write(" ");
writer.Write(" " + this.Request.Url.AbsoluteUri.ToString() + "");
writer.Write(" ");
writer.Write(" en-us");
writer.Write(" " + DateTime.Now.ToUniversalTime().ToString() + "");
writer.Write(" " + DateTime.Now.ToUniversalTime().ToString() + "");
writer.Write(" ");
writer.Write(" Dynamic page generator");
writer.Write(" ");writer.Write(" " + this.Request.Url.AbsoluteUri.ToString() + "");
writer.Write(" ");
RenderChildren(nw);
if (sb.ToString().IndexOf(" ") > 0)
writer.Write(Util.StripHTML(sb.ToString().Substring(sb.ToString().IndexOf(""))));
else
writer.Write(Util.StripHTML(sb.ToString()));
writer.Write("");
writer.Write(" " + DateTime.Now.ToUniversalTime().ToString() + "");
Guid g = new Guid();
writer.Write(" " + g.ToString() + "");
writer.Write(" ");writer.Write(" ");
}
else
{
base.Render(writer);
}
}
}

Creating a DotNetNuke menu out of an Asp.Net menu
So I tend to use Dotnetnuke alot for my side projects and its just generaly a good portal. But the default solpartmenu was always a creative challange making it look good. And the Asp.net menu provider seems to have a lot of code in it. So i looked around and saw some free menus, but they where always quirky… and when i used reflector on them i could see why.
Which led to this posting. As you can see my code is always very simple, i hate re inventing the wheel. What this control is doing is populating the menuitemcollection.

using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI.WebControls;
namespace QuickMax.UI
{
public class DnnAspNetMenu : System.Web.UI.WebControls.Menu
{
DotNetNuke.Entities.Modules.PortalModuleBase _DnnBase;
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
_DnnBase = new DotNetNuke.Entities.Modules.PortalModuleBase();
foreach (DotNetNuke.Entities.Tabs.TabInfo tab in _DnnBase.PortalSettings.DesktopTabs)
{
if (tab.IsVisible && tab.Level == 0)
{
bool badd = false;
foreach (DotNetNuke.Security.Permissions.TabPermissionInfo tbi in tab.TabPermissions)
if (_DnnBase.UserInfo.IsInRole(tbi.RoleName))
badd = true;
if (badd)
{
MenuItem mnuItem = new MenuItem();
mnuItem.Text = tab.TabName;
mnuItem.NavigateUrl = tab.FullUrl;
mnuItem.Selected = tab.TabID.Equals(_DnnBase.PortalSettings.ActiveTab.TabID);FillChildren(ref mnuItem, tab);
this.Items.Add(mnuItem);
}
}
