TIP: How to use form labels with ASP.NET controls

Problem:

You want to use <label> to point to fields in your ASP.NET controls, but due to HTML ID mangling, you cannot.

Solution:

Walk the control tree on load and update the "for" attribute on the <label>.

For example, let's say you have the following code in your control:

<label for="UserName">User Name</label>
<asp:textbox id="UserName" runat="server" columns="30">

First, add runat="server" and an ID to your <label> like so:

<label ID="UserNameLabel" for="UserName" runat="server">
User Name</label>
<asp:textbox id="UserName" runat="server" columns="30">

The ID keeps Visual Studio happy.

Then, in your Page_Load(), call the following helper function:


private void UpdateLabelsWithClientID(Control c)
{
foreach (Control c1 in c.Controls) UpdateLabelsWithClientID(c1);
if (c is HtmlGenericControl && ((HtmlGenericControl)c).TagName == "label")
{
string controlName = ((HtmlGenericControl)c).Attributes["for"];
Control c2 = this.FindControl(controlName);
if (c2 != null) ((HtmlGenericControl)c).Attributes["for"] = c2.ClientID;
}
}

If you are in an ASP.NET control, you would call it as UpdateLabelsWithClientID(this);.

SiN 1 in SiN: Episodes

Before we started working on SiN: Episodes, one of the things we started working on to properly learn Source was a Source engine version of the original SiN ala Half-Life: Source.  A lot of the work was done by Dale Broadbent.

It didn't get very far and barely functions, but there's enough here that some Source engine modders might get a kick out of it.

What is here requires S:E1 to work. Use at your own risk. No warranties are expressed or implied.

Moving sucks.

Unpacking sucks more.

The first is done.

The second, nowhere near.

Sitefinity: Clean Up Search Results

Problem:

You are using Sitefinity 3.x and your page templates and other non-desirable parts of the pages are showing up in search results.

Reason:

Sitefinity spiders your site instead of searching the data. For the most part, this is a good thing, but it pollutes your search data.

Workaround:

Sitefinity gives us the tools to hide the template from the search spider, but they are rather hidden. To use this workaround, I am going to work under the assumption that all of your templates have a standardized naming scheme for their ContentPlaceHolder objects. For example, all of my pages have the main content in a ContentPlaceHolder named "Content," my sidebar is in a ContentPlaceHolder named "SideBarContent," and so on.

First, create a new master page that is empty except for the ContentPlaceHolder objects you want included in the search results and the header tag ContentPlaceHolder. Since I only want what is in my primary content area to appear in the search results, I have one ContentPlaceHolder in my body named "Content." Upload this into Sitefinity.

Second, if you do not have an App_Code folder in your Sitefinity project, add one to the project root.

Third, create a BasePage class. This class will inherit from InternalPage. Override the OnPreInit() function and drop in the following code...


base.OnPreInit(e);
if (CmsContext.IsCrawlerRequest)
{
this.MasterPageFile = "~/App_Master/SearchOverrideMasterPage.master";
}


...where SearchOverrideMasterPage.master is the name of the new master page you want to uploaded in step one.

Fourth, go into the Sitefinity folder and edit cmsentrypoint.aspx. Change...
Inherits="Telerik.Cms.Web.InternalPage"
...to be...
Inherits="ClassNameOfBaseClass"
...where ClassNameOfBaseClass is the name of the class you created in Step 3.

Fifth, go into your App_Data/Search folder and delete the folders contained therein to delete the current search indices and results.

Finally, go into Sitefinity's Administration tab and under Services / Search, click "Start indexing" under each search index.

Sitefinity: Making a Custom Site Map

As part of a redesign of our current website at work, we're going to be changing to Sitefinity for our CMS.

The only downside is that working sans JavaScript is still a fairly big requirement for us and some of the built-in controls rely on JavaScript to function.

So...I'm rewriting some of the controls.

Here is a simple sitemap control that works with Sitefinity. Control is written in VB.NET, set up for CSS styling, and is free for customization as you see fit.
