SharePoint 2010 Static Web Part to read Page Properties

• Create a new page property by creating a new Site Column
• Edit the Page content type and add the new Site column
• Now all pages will have the new property to edit
• Create your web part to read the Page Property, like

try
{
    if (SPContext.Current.Fields.ContainsField("Your Page Property Name") && SPContext.Current.Item["Your Page Property Name"] != null)
        myString = SPContext.Current.Item["Your Page Property Name"].ToString();
}
catch { }

• Install and Deploy the web part on the server
• Find the public key token of your part by looking it up under c:\windows\assemblies
• Register the web part as static in your masterpage or page layout:

<%@ Register Tagprefix="Applicable" Namespace="ApplicableWebPartLib.TwitterBlock" Assembly="ApplicableWebPartLib, version=1.0.0.0,Culture=neutral,PublicKeyToken=2ee629bf628499ee" %>

• Use the web part on your page layout or master page:

<Applicable:TwitterBlock runat="server"></Applicable:TwitterBlock>
